Question

difference between embryosac and endosperm

Answer 1

Cotyledon and Endosperm.Endosperm, unlike the cotyledon, originates by the union of male nuclei and polar nuclei of embryo sac.

Differences:
• In dicots, endosperm is digested completely before the seed germinates, whereas cotyledon remains until the seedling is capable of photosynthesis.
In monocots, cotyledon is important in food absorption, whereas endosperm serves as a food storage tissue.
• Usually, in mature seeds of dicots, cotyledon is present while endosperm is absent.
• Endosperm, unlike the cotyledon, originates by the union of male nuclei and polar nuclei of embryo sac.
• In dicots, endosperm is digested completely before the seed germinates, whereas cotyledon remains until the seedling is capable of photosynthesis.
• In dicots, cotyledon completely absorbs the food stored in endosperm.
