RBSE Class 6 Science Chapter 7 Notes Getting to Know Plants

→ A variety of plants exists all around us.

→ On the basis of height, nature of stem and branches, mc|)st plants can be classified into three categories : herbs, shrubs and trees.

→ There are creepers and climbers also, which are different from herbs, shrubs and trees.

→ The stem helps in upward movement of water, the water and minerals go to leaves and other plant parts attached to the stem. It also conducts food from leaves to other parts of the plant.

→ Leaf usually has a petiole and lamina.

→ The pattern of veins on the leaf is called Venation. It can be reticulate or parallel.

→ The leaves prepare food. This food travels through the stem and is stored in different parts of plant.

→ The leaf uses water to make food, the leaves also lose water through transpiration.

→ Roots hold the plant firmly in the soil.

→ Roots are mainly of two types : taproot and fibrous root.

→ Roots absorb water and minerals from the soil.

→ We eat some of these roots, like carrot, radish, sweet potato, turnip and tapisca. We also eat many other parts of a plant where food is stored.

→ Plants having leaves with reticulate venation have tap roots while plants having leaves with parallel venation have fibrous roots.

→ The different parts of flower are - sepals, petals, stamen and pistil.

→ The number of sepals, petals, stamens and pistils may also be different in different flowers. Some of these parts may even be absent at times.
