Mitosis And Meiosis

Question 1

What are the 5 stages of MITOSIS? State what happens in each stage.

Answer 1

Interphase - Chromosomes double up
Prophase - Double chromosomes are visible
Metaphase - Chromosones line up in the middle
Anaphase - Cells split
Telophase - Chromosones separate to the two cells as half of each type of chromosome

Question 2

True/False:

Mitosis is a controlled process.

Answer 2

True

Question 3

How does cancer occur?

Answer 3

When mitosis starts dividing uncontrollably

Question 4

Where does mitosis happen?

Answer 4

In all cells except the gametes

Question 5

Why does mitosis happen? Name 5 reasons.

Answer 5

To replace damaged cells
Repair damaged tissues
Growth areas such as the growing tip of a plant root or shoot
Asexual reproduction
Vegetative propagation

Question 6

What is meiosis?

Answer 6

Process that takes place in the reproductive organs
Similar to mitosis but the “daughter” cells have HALF the number of chromosomes as the original cells - HAPLOID
From 1 “parent” cell 4 “daughter” cells are produced

Question 7

Name 3 differences between MITOSIS and MEIOSIS.

Answer 7

Mitosis produces 2 daughter cells while meiosis produces 4
Mitosis daughter cells are identical to the parent cell while meiosis daughter cells are not
Mitosis daughter cells are diploid while meiosis daughter cells are haploid
