Question

3
In the given figure of Cotyledon the parts labelled as A and B respectively
are
(A)* fruit, shoot
(B) - primary shoot, primary root
(C) secondary root, primary shoot
(D) bud, leaf.​

Answer 1

The parts labeled as A and B are primary shoot and primary root.

Option (b) is correct.

Explanation:

• In cotyledon plants, the stage of primary growth occurs as a result of cell division when the cells divide rapidly.
• The rapid division of cells takes place in the meristem cells which are located at the tips of the root and shoot.
• Water enters the plant through the roots and the plant absorbs sunlight from the upper tips known as "shoot" for photosynthesis.
