Question

B.
Answer the following questions :
1. What is photosynthesis?
2. Name two plants whose modified stem can store food.
3. Name the various types of leaf venation.
4. What type of root a plant of wheat has?​

Answer 1

Answer:

1) the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

2) Plants whose stems are modified to store food are potato, ginger, turmeric, Colocasia and Zaminkand.

3) The arrangement of veins and veinlets on the lamina of a leaf is called venation. There are two types of venation, reticulate and parallel venation.

4) The wheat plant has two types of roots, the seminal (seed) roots and roots that initiate after germination, the nodal (crown or adventitious) roots.
