Spermotgenisis

Question 1

What is the first step in spermatogenisis 1/5

Answer 1

The diploid primoridal germ cell divides several times by mitosis to form diploid spermatogonia

Question 2

spermatogenisis 2/5

Answer 2

the spermatognoia then grow without further division until they are big enough to be called primary spematocytes

Question 3

spermatogenisis 3/5

Answer 3

The spermatocytes undergo meiosis. The first meiotic division results in 2 haploid cells called secondary spermatocytes

Question 4

spermatogenisis 4/5

Answer 4

The second meiotic division results in 4 haploid cells called spermatids

Question 5

spermatogenisis 5/5

Answer 5

The spermatids then differentiate into the tubules of the testes to from spermatozoa the active gametes capable of fertilising an ovum

Question 6

How are primary spermatocytes form

Answer 6

The spermatognia then grow without further divison until they are big enough

Question 7

How are spermatids formed

Answer 7

Spermatocytes undergo meiosis . The first meiotic division results in 2 haploids cells called secondary spermatocytes

The second meiotic division results in 4 haploid cells called spermatids

Question 8

How is spermatozoa formed

Answer 8

The spermatids then differentiate in the tubules of the testes to form spermatozoa
