Multicellular Organisms - Production new cells, Mitosis

Question 1

• What is Mitosis?
• Give 2 points describing its function

Answer 1

The division of cells
- Provides new cells for growth and repair
- Maintains the diploid chromosome complement of new cells.

Question 2

Define a diploid cell and a haploid cell

Answer 2

Diploid cell - cell with two copies of each chromosome
Haploid cell - cell with one set of chromosomes

Total num of chromosomes in diploid cells? → 2ⁿ

n being the number of haploid (one side of the “Y”) cells present

Question 3

• Define the Equator of a cell
• Define Spindle fibers

Answer 3

Equator - Middle of the cell where chromatids line up

Spindle fibers - Strands of protein that cell uses to separate the chromatid pairs

Question 4

Explain how the diploid chromosome complement is maintained during mitosis

Answer 4

The parent cell divides to produce the daughter cells, ensuring no genetic info is lost so the cell can function properly.
