After fertilization
The cell or the zygote divides through mitosis in which each cell is doubles by dividing itself into two.
The zygote then travels through the fallopian tube to the uterus for next process.
The zygote is pushed into to lining of uterus through cilia in order to get nutrition by the process called implantation.
Then it draws nutrition from there any grows further to survive.
Then it grows and finally all the body organs are formed.
The first organ formed is heart.
The baby is joined to the mother womb through fallopian tube.

Animal Development Explain the role of fertilization in the process of axis formation in amphibians.
After fertilization but before an embryo implants, it undergoes a period of cell division without an increase in size. What is the name of this process and where is the embryo when it occurs? …. Is it mitosis? And why

describe double fertilization in angiosperms. include the following points in your response. - which cell in pollen grain produces the sperm cells? what does each sperm cell join with, and in each case what develops after the sperm cell joins with another cell or nuclei ?
Lymphocyte Development 1. B cell development in the bone marrow shares may features with T cell development in the thymus. A) Discuss the two major goals of lymphocyte development? B) Compare and contrast the ordered steps of receptor rearrangement in B and T cells. C) What cell surface molecules make up the pre-B cell receptor and the pre-T cell receptor and are they only required for development?
