biology cell cycle ,mitosis, meiosis

Question 1

what are the three stages of the cell cycle?

Answer 1

1.Growth
2.Dna replication+mitosis
3. division (cytokinesis)

Question 2

what happens in the first stage of cell cycle?

Answer 2

Cell grows and increases number of sub-cellular structures inside( mitochondria and ribosomes)

Question 3

what happens in the second stage of the cell cycle?

Answer 3

DNA is duplicated so two new cells each have a full set of DNA.

Question 4

what happens in the third stage of the cell cycle?

Answer 4

The cell membrane and cytoplasm pull apart forming two daughter cells, each having the same amount of DNA which can now contribute to Growth, development or repair. And process of cell cycle repeats again.

Question 5

What is a haploid cell?

Answer 5

A cell that contains half the genetic material of a normal cell.

Question 6

what is a diploid cell?

Answer 6

A cell that contains two sets of genetic information.

Question 7

how many divisions are there in meiosis?

Answer 7

2 divisions

Question 8

how many copies of a gamete is made by meiosis?

Answer 8

4 genetically unique copies are made because all the chromosomes shuffle up during meiosis to form haploid cells.

Question 9

what is a male and female gamete called?

Answer 9

male= sperm(produced in testis)
female= ova( produced in ovaries)
