Question

Explain the process of embryogenesis.​

Answer 1

Embryogenesis

• Multicellular structure developed from the zygote is called embryo.

• Embryo is the most important part of the seed, it is diploid.

• In angiosperms the zygote is divided by a transverse wall form an upper and lower cell.

• The upper cell is seen towards the micropylar and the lower cell towards the chalazal end.

• Upper cell also called hypobasal or basal cell lower cell is called epibasal or terminal cell.

• This two celled stage is called two celled pro embryo.

• The lower terminal cell divides and redivides to form embryo proper.

• Embryo proper form the multicellular embryo.

Answer 2

the process of development of zygote into an embryo is called embryogenesis.
