THE endosperm is usually a triploid tissue which supports the growth and germination of the embryo, and stores reserve food materials in mature seeds.

When hybrid seeds fail to develop, the reason often lies in the endosperm—a tissue in plant seeds that provides nutrients to the growing embryo, much like the placenta nourishes mammalian embryos.

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo ...

Inside the seed is something called an embryo, a tiny little plant surrounded by stuff that feeds it. This is called the endosperm. The outside of the seed has a coat which surrounds the embryo to ...

When hybrid seeds fail to develop, the reason often lies in the endosperm—a tissue in plant seeds that provides nutrients to the growing embryo, much like the placenta nourishes mammalian embryos.

Then, one of the sperm cells is fertilized with the egg cell to develop into the embryo, while the other is fertilized with the central cell to develop into endosperm. Professor Higashiyama and his ...
