Seed germination is the sprouting of a seed and growth of the embryo present inside the seed into a seedling or young plant capable of independent existence. Refer the given figure showing seed germination and mark the incorrect option. (A) Cotyledons are brought out of the soil by the greater growth of hypocotyl (B) Cotyledons become green and functional as first leaves of the seedling (C) The hypocotyl does not elongate much, instead the epicotyl grows and takes the plumule above the soil (D) This kind of germination is found in seeds of beans

Given figure illustrates epigeal seed germination which occurs in bean seeds. In this type of seed germination, cotyledons are pushed out of the soil by greater growth of hypocotyl. Hypocotyl grows actively and becomes curved to protect the plumule and cotyledons from friction of soil. After coming out of the soil surface, the hypocotyl straightens. The loosened seed coats fall down, cotyledons turn green and become photosynthetic to function as first leaves of the seedling.

Cotyledons are brought out of the soil by the greater growth of hypocotyl

Cotyledons become green and functional as first leaves of the seedling

The hypocotyl does not elongate much, instead the epicotyl grows and takes the plumule above the soil

This kind of germination is found in seeds of beans
