Topic 2A - Cell Structure And Division

Question 1

Mitosis

Answer 1

A parent cell divides to produce two genetically identical daughter cells.
They contain an exact copy of the DNA of the parent cell.

Question 2

Importance of mitosis

Answer 2

Needed for growth and for repeating damaged tissues

Question 3

G1 phase

Answer 3

Cell grows and new organelles and proteins are made

Question 4

S phase

Answer 4

Cell replicates it’s DNA, ready to divide by mitosis

Question 5

G2 phase

Answer 5

Cells keep growing and proteins needed for cell division are made

Question 6

Interphase

Answer 6

The cell carries out normal functions but also prepares to divide. The cells DNA is unravelled and replicated to double its genetic content.
The organelles are also replicated so it has spare ones, and its ATP content is increased.
