Stamens are the male part of the flower. They produce pollen grains which house the male gametes of a plant.

Leaves can be of two types - simple leaves and compound leaves.
A simple leaf is a single leaf with an undivided lamina.
A compound leaf is a leaf which has its lamina divided into a number of leaflets.

Based on the mode of nutrition, plants can be classified into two - autotrophs and heterotrophs.
Example of an autotrophic plant is neem tree (any green plant).
Example of a heterotrophic plant is Cuscuta (a parasitic plant).

Answer: Option A. ->
:
Each function: 1 Mark
[Mention any two]
1. Stem helps in transportation of absorbed water and nutrients through vascular tissue from roots to leaves.
2. Stem also transports food from the leaves to different storage organs.
3. Sometimes stem can store food which is mostly underground.
4. Stem can store water by becoming fleshy as in desert plants.
5. Green stem can perform photosynthesis when leaves are reduced or absent as in desert plants.

Answer: Option A. ->
:

Root modification + Example:1 Mark each
[Mention any three] 

1. Storage roots are the roots modified to store food in them. E.g. Carrot, turnip, radish, sweet potato, etc.
2. Respiratory roots are the roots modified for respiration.
E.g. Roots of mangrove plants. 
3. Parasitic roots are the roots which arise from the stem and absorb nourishment from the host plant. E.g. Cuscuta.
4. Climbing roots are the roots which help the plant to climb and cling onto a support. E.g. Money plant, betel.
5. Reproductive roots are the roots which help in the process of producing the offspring. E.g. sweet potato.
6. Prop roots are the roots which offer support to the huge structure of the tree. E.g. Banyan tree

Each category: 1 Mark
 

There are 5 categories of plants - herbs, shrubs, trees, creepers and climbers.
1. Herbs are non-woody plants that have green and tender stems with few branches.
2. Shrubs are taller than herbs and have stems branching out at the base.
3. Trees are tall, woody plants that have many branches on a single stem.
4. Creepers are the plants with weak stems that grow along the ground by slowly spreading themselves out.
5. Climbers are the plants that need support from other structures and they climb on them.

Naming the parts: 1 Mark
Definition: 1 Mark each 
The flower is made of sepals, petals, stamens, and pistil. 
1. Sepals are green, leaf-like structures around the base of a flower. They protect the bud before it blooms into a flower.
2. Petals are brightly coloured portions of a flower. The petals are collectively called the corolla.
3. Stamens are the male reproductive parts of a flower. Stamen is made up of a filament and anther. The anthers bear pollen grains which carry the male gametes of a plant.
4. Pistil is the female reproductive part of a flower. It is made up of the stigma, the style and the ovary. Ovules are present inside the ovary. The female gamete or egg cell is present inside the ovule.

Each part: 1 Mark
The different parts of a plant are - leaf, stem, roots, fruits, and flowers.
1. Leaves are the structures which develop on branches. These are green in colour due to the presence of a pigment called chlorophyll. They are considered to be food factories of the plant because photosynthesis occurs in the leaves. 
2. The stem is the part of the plant seen above the ground. It bears the leaves, flowers and fruits. It is almost green or woody. It grows towards sunlight.
3. The roots of a plant are mostly seen underground and appear brown in colour. Root bear tiny thread-like structures over called root hairs. Roots absorb water.
4. The flower is the reproductive structure of the plant. Flower helps the plant to give rise to new plants by the process of sexual reproduction.
5. Fruits are produced by flowers after fertilisation. Fruit is the fertilised ovary. The fruit contains seeds inside them.
