How endosperm cells are formed What does endosperm develop from

It is proliferated and differentiated into endosperm cells by a fertilized polar nucleus, and then the endosperm is formed.

The fertilized polar nucleus is formed by one sperm nucleus and two polar nuclei, so the chromosome composition is generally triploid but different organisms are different.

After a flower has undergone pollination and fertilization, the ovary is grand.

The developmental status is:

It can be seen that the embryo and endosperm of corn are developed from the fertilized egg and the fertilized polar nucleus respectively

Question 1: What do the germ, hypocotyl, radicle and cotyledons develop into The germ develops into stems and leaves, the hypocotyl develops into the junction between the stem and the root, the radicle develops into the root, the cotyledons store nutrients, and the sea fruit has the endosperm, and the nutrients are in the endosperm.

Question 2: What will the endosperm develop into The germ develops into stems and leaves, the hypocotyl develops into the junction between the stem and the root, the radicle develops into the root, and the cotyledons store nutrients, and if there is an endosperm, the nutrients are in the endosperm.

The endosperm is generally absorbed during development.

Question 3: What are the young leaves, germ, radicle, endosperm, bud axis, cotyledons, etc., which develop into young leaves.

Germ stems and leaves.

Radicle root.

The endosperm is a part of the seed that provides energy for the germination of the seed's terrestrial state, and cannot develop.

Bud shaft stem.

Cotyledons do not develop.

Question 4: What does the endosperm develop from after fertilization The endosperm is developed from fertilization.

Question 5: What is the role of germ, hypocotyl, radicle, endosperm, and cotyledons Radicles are the first to break through the seed coat and grow into roots. The hypocotyl elongates, and the germ breaks through the seed coat and grows on its back to develop into stems and leaves.

The endosperm functions as a reservoir of nutrients. cotyledons; (monocots): transports the organic matter in the endosperm to the germ, hypocotyl, and radicle; (Dicotyledons):

Store nutrients.

This is my hard work, there is no copy, choose me

Question 6: What is the origin of "peanuts"? ( A endosperm b ovule c ovary d ovary peanut belongs to the fruit, is developed from the ovary, peanut rice is a seed, is developed from the ovule, so choose b.)

Problem 7: I'm dizzy. What exactly is the development of seeds, embryos, and endosperms? The entire ovule develops into seeds.

The ovules contain:

Bead quilt, developed into seed coat.

A fertilized egg, which develops into an embryo.

Fertilizes the polar nucleus and develops into the endosperm.

The seed coat, embryo, and early endosperm are all components of the harvest.

Question 8: What do the germ, hypocotyl, radicle and cotyledons develop into The germ develops into stems and leaves, the hypocotyl develops into the junction between the stem and the root, the radicle develops into the root, the cotyledons store nutrients, and the sea fruit has endosperm, and the nutrients are in the endosperm.

Question 9: What will the endosperm develop into The germ develops into stems and leaves, the hypocotyl develops into the junction between stem and root, the radicle develops into roots, and the cotyledons store nutrients, and if there is endosperm, the nutrients are in the endosperm.

The endosperm is generally absorbed during development.

Question 10: What are the young leaves, germ, radicle, endosperm, bud axis, cotyledons, etc., which develop into young leaves.

Germ stems and leaves.

Radicle root.

The endosperm is a part of the seed that quietly provides energy for the germination of the seed and cannot develop.

Bud shaft stem.

Cotyledons do not develop.

Look at the chromosomes. Endosperm cells have three sets of chromosomes (1 3 from the father and 2 3 from the mother) while ploidy normal somatic cells are two sets of chromosomes. So it's not.

Biology!

First, figure out what it's called.

Somatic cells"Then, figure out how endosperm cells are formed.

In the end, the problem is solved!

I think so. Reason: According to secondary school textbooks, for plants, their constituent cells can be broadly divided.

Somatic cells and germ cells are divided by the function of the cell. The function of endosperm cells is to provide nutrients for the developing embryo and is not involved in reproductive activities, so endosperm cells should belong to somatic cells.

Therefore, "the number of chromosomes in endosperm cells is multiple that of somatic cells."

It should be "The number of chromosomes in endosperm cells is multiple that of (normal) somatic cells."
