Question

What is endosperm? what is endosperm? the female portion of a flowering plant the male portion of a flowering plant the leaves that are a part of the embryo tissue that develops into a protective seed coat surrounding the embryo via cotyledons, a source of food for the embryo?

Answer 1

Endosperm is a nutritive tissue in angiosperm seeds that provides food to the developing embryo, formed from a second fertilization event, and may eventually be absorbed by the cotyledons.

Step-by-step explanation:

Endosperm is a tissue found in the seeds of angiosperms that serves as a source of food for the embryo. This nutritive tissue is the result of a second fertilization event that occurs besides the one that creates the zygote. Initially, the endosperm develops in a 'free-nuclear' pattern and may later form cell walls to become a more structured tissue.

In many angiosperms, the endosperm provides nutrients to the embryo as it develops. Eventually, in some plants, the endosperm is absorbed and the nutrients are transferred to the cotyledons, which further nourish the growing embryo. The seed also consists of a protective seed coat and the embryo that will develop into a new plant.

Answer 2

The endosperm is via cotyledons. It is a source of food for the embryo. The endosperm provides nutrition for the developing embryo and this results in increasing survival rates.
The endosperm has allowed the angiosperms to become the most numerous and diverse plant group.
