V. Morphology of Flowering Plants Short Answer Questions (4 Marks)
Question 1.
Explain different regions of root with neat labelled diagram.
Answer:
The root is divided into distinct regions that perform specific functions to facilitate growth and nutrient absorption. A typical young root shows 4 regions :
- Region of root cap
- Region of meristamatic activity
- Region of elongation
- Region of maturation
Region of Root Cap :
- A thimble-like structure at the apex of the root called the root cap.
- It protects the tender root tip as it grows through the soil.
Region of Meristematic Activity :
- Just above the root cap, this region consists of small, thin-walled cells with dense protoplasm that divide repeatedly.
- These cells are responsible for the continuous growth of the root.
Region of Elongation :
- Located above the meristematic region, this area contains cells that elongate and enlarge.
- This elongation is responsible for the root’s growth in length.
4. Region of Maturation:
- Above the elongation region, cells undergo differentiation and mature.
- It is in this region that root hairs form from epidermal cells.
- These root hairs are vital for absorbing water and minerals from the soil.
These regions work together to help the root grow, absorb nutrients, and protect the root tip from damage as it moves through the soil.
Question 2.
Explain different types of phyllotaxy with examples.
Answer:
Phyllotaxy is the arrangement of leaves on the stem or branch. It plays an essential role in maximizing light capture for photosynthesis. There are three main types of phyllotaxy. They are : 1. Alternate Phyllotaxy, 2. Opposite Phyllotaxy and 3. Whorled Phyllotaxy
1. Alternate Phyllotaxy : In this type, a single leaf arises at each node in an alternate manner on the stem.
Examples : China rose, Mustard, Sunflower.
2. Opposite Phyllotaxy : In this type, a pair of leaves arise at each node and lie opposite to each other.
Examples : Guava, Calotropis.
3. Whorled Phyllotaxy : When more than two leaves arise from a single node and form a whorl, the arrangement is called whorled. Example : Alstonia.
Question 3.
Describe the arrangement of floral members in relation to their insertion on thalamus.
Answer:
The arrangement of floral members ( sepals, petals, stamens, and carpels ) on the thalamus (the flower’s base) is based on their position relative to the ovary. There are three types:
1. Hypogynous Flower
2. Perigynous Flower
3. Epigynous Flower.
1. Hypogynous flower:
- Thalamus is convex or cone-shaped.
- Gynoecium occupies the highest position on the thalamus.
- Other floral parts of the flower are situated below the gynoecium.
- Position of the ovary is superior.
Ex: Mustard, China rose, Brinjal.
2. Perigynous flower:
- Thalamus is saucer or shallow cup-shaped.
- Gynoecium is situated in the centre of the thalamus.
- Other floral parts of the flower are located on the rim of the thalamus almost at the same level.
- Position of the ovary is half inferior / half superior.
Ex: Plum, Rose, Peach.
3. Epigynous flower:
- Thalamus is deep cup shaped.
- The margins of the thalamus grow upward enclosing the ovary completely.
- Thalamus gets fused with the ovary wall.
- Other floral parts of the flower arise above the ovary from the margin of the thalamus.
- Position of the ovary is inferior.
Ex : Guava, Cucumber, Ray and disc florets of sunflower.
Question 4.
‘The flowers of many angiospermic plants which show sepals and petals, differ with respect to the arrangement of sepals and petals in respective whorls’. Explain.
Answer:
Yes, in many angiospermic (flowering) plants, sepals and petals may differ in how they are arranged within their whorls. This arrangement is called aestivation, and it varies among species. It is of 4 types:
1. Valvate
2. Twisted
3. Imbricate
4. Vexillary
1. Valvate Aestivation : Sepals or petals just touch each other at the margins, without overlapping.
Example: Calotropis.
2. Twisted Aestivation : One edge of a sepal or petal overlaps the next, and the other edge is overlapped by the previous one. Example: China rose, cotton.
3. Imbricate Aestivation : The margins of sepals/petals overlap irregularly, not in any fixed pattern.
Example : Cassia, gulmohar.
4. Vexillary Aestivation (also called Papilionaceous) :
- It is commonly found in Fabaceae.
- Corolla has 5 petals.
- It is a special type where the largest petal (standard) overlaps the two lateral petals (wings), which in turn overlap the two smallest petals (keel). Example: Pea, bean.
Question 5.
Describe any four types of placentations found in flowering plants.
Answer:
Placentation is the arrangement of ovules within the ovary of flowering plants. Five common types are:
- Marginal Placentation
- Axile Placentation
- Parietal Placentation
- Free Central Placentation
- Basal placentation
Marginal Placentation :
- The placenta forms a ridge along the ventral suture, and ovules are arranged in two rows.
- It is found in monocarpellary ovaries. E.g. : Pea
Axile Placentation: The placenta is on a central axis in a multilocular ovary, with ovules attached to this axis.
E.g.: China rose, Tomato, and Lemon.
Parietal Placentation: Ovules develop on the inner wall of a unilocular ovary, which may appear two-chambered due to a false septum. E.g.: Mustard and Argemone.
Free Central Placentation: Ovules are attached to a central axis, but the ovary remains unilocular as there are no septa.
E.g.: Dianthus and Primrose.
Basal placentation: The Placenta develops at the base of the ovary, single ovule is attached to the placenta.
E.g. : Sunflower, Marigold.
Question 6.
Write a brief note on semi technical description of a typical flowering plant.
Answer:
1. In a semi-technical description, the flowering plant is described briefly using simple scientific language in a proper sequence.
2. The description starts with the habit of the plant, followed by vegetative characters like root, stem, and leaves, and then the floral characters including inflorescence and flower parts.
3. The floral formula is a symbolic representation of the structure of a flower.
Common symbols include:
- K : Calyx, C : Corolla, P : Perianth, A : Androecium, G : Gynoecium
- Symbols for gender: ♂(male), ♀(female),☿(bisexual)
- Symmetry : ⊕ for actinomorphic (radial), % for zygomorphic (bilateral)
- Ovary position : underline (G) for superior, overline (G) for inferior
- Br for bracteate flowers, Ebr for ebracteate (bracts absent), Brl for bracteolate, Ebrl for ebracteolate (bracteoles are absent)
- Fusion is shown by brackets (e.g.: C(5)), and adhesion by lines above parts (e.g. : C)
4. Floral formula also indicates the number of free or united (within brackets) members of the corresponding whorl as subscript of the respective symbol. It also shows cohesion (union among similar members) and adhesion (union between dissimilar members).
5. A floral diagram provides information about the number of parts of a flower, their arrangement and the relation they have with one another.
6. The mother axis represents the posterior side of the flower and is indicated as a dot or a circle at the top of the floral diagram.
7. Calyx, corolla, androecium and gynoecium are drawn in successive whorls, calyx being the outermost and the gynoecium being in the centre represented by a diagram of T.S. of ovary.
8. The bract represents the anterior side of the flower and is indicated at the bottom of the floral diagram.
Question 7.
Give an account of floral diagram.
Answer:
- A floral diagram is a visual representation of the structure of a flower, showing the arrangement, number, and position of floral parts such as sepals, petals, stamens, and carpels. It helps in understanding the floral morphology in a clear and scientific way.
- The diagram starts with a dot at the top to indicate the mother axis (the position of the stem). Floral parts are shown in concentric circles : calyx on the outermost side, followed by corolla, androecium, and gynoecium in the center.
- Fusion of floral parts is shown using brackets (for cohesion) and lines (for adhesion). The diagram also reflects flower symmetry – actinomorphic (radial) or zygomorphic (bilateral), and indicates ovary position (superior or inferior).
- Floral diagrams are essential in plant identification and classification, offering a quick overview of floral structure.

Answer:
VI. Morphology of Flowering Plants Long Type Questions (8 Marks)
Question 1.
What is a flower? Describe the parts of a typical angiosperm flower.
Answer:
A flower is the reproductive unit of angiosperms and is meant for sexual reproduction. It develops on the thalamus or receptacle and typically has four whorls: calyx, corolla, androeciurn, and gynoecium. Calyx and corolla are accessory parts, while androecium (male) and gynoeciurn (female) are reproductive. Flowers may be bisexual or unisexual, and can be actinomorphic (radial symmetry), zygomorphic (bilateral), or asymmetric. Based on ovary position, flowers are hypogynous (superior ovary), perigynous (half-inferior), or epigynous (inferior ovary).
Parts of a Typical Flower:
1. Calyx:
- It is usually green in colour, leaf-like and protects the flower in the bud condition.
- It is the outer most whorl of a flower. It is made up of units called sepals.
- The calyx may be gamosepalous (fused) or polysepalous (free).
2. Corolla: It is made of colourful petals to attract pollinators. It may be gamopetalous or polypetalous.
Aestivation types include:
- Valvate – Just touching (e.g. : Calotropis)
- Twisted – Overlapping in one direction (e.g. : China rose)
- Imbricate – Irregular overlap (e.g.: Cassia)
- Vexillary – Standard, wings, keel (e.g. : Pea)
3. Androecium :
- It is the whorl present next to the corolla.
- The androecium mainly consists of stamens which are the male reproductive unit of a flower.
- A stamen is composed of two parts i.e., anther and filament.
- The anther is the bilobed structure and each lobe has two chambers called pollen sacs.
- The stalk of the stamen is called a filament. Inside the anther, pollen grains are formed. A sterile stamen is called staminode.
- Stamens of a flower may be united with other floral parts.
- When stamens are attached to petals, they are Epipetalous (Brinjal), when attached to the perianth, they are called Epiphyllous (Lily).
- The stamens in a flower may be free (Polyandrous) themselves or may be united among.
- They may be
1. Monadelphous the filaments of all the stamens may be united into one bundle (China rose).
2. Diadelphous- into two bundles (Pea).
3. Polyadelphous- into more than two bundles (Citrus). - In Salvia- Didynamous stamens are seen meaning two longer and two shorter stamens in a flower.
- In mustard- Tetradynamous stamens are seen, meaning four are longer and two are shorter.
4. Gynoecium:
- The innermost whorl and female reproductive part of a flower is called gynoecium.
- It consists of carpels. A carpel is composed of three parts: stigma, style and ovary.
- Ovary is the enlarged basal part on which lies the style.
- The style connects the ovary to the stigma.
- The stigma is the receptive surface for pollen grains.
- Each ovary bears one or more ovules attached to a flattened cushion like placenta,
- When more than one carpel is present, they may be free (Lotus, Rose) and are called apocarpous or fused they are syncarpous (Mustard, Tomato).
- After fertilization, the ovary develops into fruit and ovules develop into seeds.
Question 2.
Write about the key characteristics of Solanaceae ?
Answer:
Key Characteristics of Solanaceae (Potato Family) :
1. Habitat and Habit:
- Mostly herbs, shrubs, and rarely small trees.
- Found in tropical, subtropical, and temperate regions.
2. Vegetative Features:
- Stem : Herbaceous or rarely woody, erect, branched, solid or hollow; hairy or glabrous. Underground stem in potato.
- Leaves: Alternate, simple, rarely pinnately compound, exstipulate, with reticulate venation.
3. Floral Characteristics :
- Inflorescence : Solitary, axillary or cymose (e.g. : Solanum).
- Flowers : Bisexual, actinomorphic (radial symmetry), pentamerous, hypogynous.
- Calyx : 5 sepals, gamosepalous, persistent, with valvate aestivation.
- Corolla : 5 petals, gamosepalous, with valvate aestivation.
