The process forming the neural tube and plate via the intercalation of cells along the medial-lateral axis and extension along the anterior-posterior axis occurs is called? a. neurulation b. embryogenesis c. convergent extension d. morphogenesis
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
|
a. neurulation
|
||
|
b. embryogenesis
|
||
|
c. convergent extension
|

|
d. morphogenesis
|
The fusion and fertilization of parental sex gametes give rise to a zygote. A zygote is the first diploid single-celled structure formed in sexual reproduction. This zygote undergoes a series of cleavage (cell divisions) to form a multicellular structure called an embryo that undergoes further energy development and maturation and is called a fetus till its birth as a baby.
