Chapter 2- Cell Growth & Reproduction

Question 1

List the Phases in Sequence

Answer 1

1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Question 2

What happens in Prophase

Answer 2

Chromosomes become visible 
The nucleolus disappears 
Mitotic spindle forms
Nuclear envelope disappears 
Chromosomes become more coiled and can be seen under a light microscope

Question 3

What happens in Metaphase?

Answer 3

All DNA lines up, usually forms a black line

Question 4

What happens in Anaphase?

Answer 4

DNA pulls apart to opposite polls of the cell

Question 5

What happens in Telophase?

Answer 5

Pinching into Two. DNA is reorganizing

Question 6

What happens when Sequence is disturbed?

Answer 6

Cancer occurs when the normal “checkpoints” regulating mitosis are ignored or overridden by a cancer cell resulting in uncontrolled cell division

Question 7

What is Meiosis?

Answer 7

A type of cell division that results in 4 daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores

Question 8

Distinguish between Meiosis and Mitosis

Answer 8

Meiosis involves 2 cell divisions

Meiosis leads to production of germ cells (which are cells that give rise to gametes) (sex cells)

Question 9

What is Mitosis

Answer 9

The division of Nucleus in which the duplicated DNA is Distributed to New Daughter Cells
