Answer 1

Answer:

I) The radicle gives rise to the roots, the hypocotyl to the lower stem, and the epicotyl to the leaves and upper stem. In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells

II) (a) Radicle: The radicle is the embryonic root of the plant,and grows downward in the soil. It is the first thing to emerge from a seed and down into the ground to allow the seed to suck up water and send out its leaves so that it starts photosynthesizing.

(b) Cotyledons: Cotyledons are the first part of a plant to emerge from the seed. They are formed within the seed along with the endosperm.
