Life is not possible without plants. We should save plants. Plants give us oxygen which is essential for life. They provide us raw materials for various purposes. They are the house of many birds and animals.

He will be able to pull out grass more easily as compared to rose plant because fibrous roots are found in grass which do not go down much deep in soil.

No, it is not a herb because sapling is a stage in the growth of the plant. A mango sapling would grow into a tree.

These are two parts of leaf :
Petiole is the part of the leaf or small stalk by which the leaf is attached to the stem.
Lamina is the flat, thin and broad part with conspicuous system of veins and veinlets.

Plants are classified into herbs, shrubs, trees, climbers and creepers on the basis of their height, type of stem and the mode of branching.

The basic parts of a flower are sepals, petals, stamens and pistil.

(i) The stem carries water and minerals from the roots to·the different parts of the plant.
(ii) The stem provides support to the branches, leaves, flowers and fruits.

Herbs are comparatively smaller plants, have green stem whereas shrubs have distinct and harder stem with branching from near the ground.

Arrangement of veins on the lamina of leaf is called venation. They are of two types:
(a)Reticulate venation
(b) Parallel venation

Sweet potato is a modified root, meant for the storage of food material.

A plant with tap root system has reticulate venation while a plant with fibrous roots has parallel venation.

No, all the leaves do not have petioles. Leaves without petiole are called sessile.

From the given characteristics, it can be concluded that the given plant is a tree.

A large number of linear structures that spread to all parts of the leaf are called veins. Whereas, the main vein (thick vein) in the middle of the leaf is called midrib.

The herb has weak green stem and it is a small plant. Shrub has thicker strong stem and the plant is bigger than the herb.

Roots help in holding the soil together. In this way, roots prevent the soil from being blown away by wind or washed away by water and help in the conservation of soil.

Banyan tree has well developed root system inside the soil. It also develops roots from its branches which grow downwards and reach the ground and grow in soil as well.

Yes, in cactus the stem is green and performs photosynthesis, to prepare food for plants.

No, all plants are of different sizes. According to their size, they are classified as herb, shrub and trees.

The leaf generally performs the function of photosynthesis.
