Question

Give two differences in each of the following pairs :
(a) Epigeal germination and hypogeal germination
(b) Coleorhiza and coleoptile.
(c) Bean seed and maize grain.​

Answer 1

Answer:

hope it will be helpful to you.

Explanation:

in epigeal germination the cotyledons are brought on the surface with the shoot during germination. this germination is mainly due to the quick elongation and curved shape of the hypocotyl.

whereas

in hypogeal germination the terminal remains below the soil surface during germination

also, the terminal part of the epicotyl is curved in order to reduce damage to the plumule from friction caused because of soil particles.

b. in coleoptile there (1) is a protective sheath. also (2) sheath covers only the plumule.

whereas

in coleorhiza there is (1) an undifferentiated sheath.

(2) this sheath covers only radicle and root cap.
