Q

What are the two types of cell division? What do they entail?

A

Sexual - Containing 2 organisms

Asexual - Contains only 1 organism that splits itself into 2 after growth

Q

How many divisions take place in mitosis?

Q

How many divisions are their amongst the cells?

A

2 as the diploid cell needs to grow, split, then split into 2(4) gamete sex cells

Q

Describe the process of Mitosis…

A

It is an asexual process that only contains one organism and is needed to produce genetically identical cells that replicate the parents genes and DNA

The DNA from a diploid (containing 2 sets of chromosomes) body cell of the organism is copied, and the cell grows larger

This diploid body cell then splits into two daughter cells that are both diploid and contain two sets of chromosomes

This process repeats and repeats

Q

What is cell division useful for?

A

Growth

Repair

Reproduction

17
Q

Why is mitosis needed?

A

Growth
Repair
Reproduction
Multicellular organisms to exist

18
Q

Does mitosis contain 1 or 2 organisms? Is it a sexual or asexual process?

A

Asexual - 1 organism

19
Q

Describe the process of meiosis…

A

It is a sexual process that is needed to produce haploid gametes (sex cells) that are genetically different

This process takes place in the testes and ovaries

The diploid egg/sperm cell copies its DNA and then divides into two separate cells

These diploid gametes then split that DNA into 2 sets of chromosomes amongst 2 different cells resulting in 4 haploid gamete cells

20
Q

How many daughter cells are produced in mitosis?

Are they diploid(2 set) or haploid(1 set)?

A

2 diploid
