Cell division

Introduction to mitosis and meiosis

Intro to mitosis vs. meiosis

The cell division process that produces body cells is called mitosis. 

The cell division process that produces sex cells is called meiosis.

Which process makes your hair and fingernails grow?

1. mitosis
2. meiosis

Cell division with the purpose of creating sperm cells. This is an example of:

1. Mitosis
2. Meiosis

In a plant, which process produces the pollen grains?

1. mitosis
2. meiosis

If you cut yourself, which process heals the wound?

1. mitosis
2. meiosis

Haploid vs. diploid

Human cells have 46 chromosomes - that's 23 homologous (matching) pairs. 

This total number of chromosomes is called the diploid number (2n).

Gametes (sex cells) have half the diploid number. This is called the haploid number, shown as (n).

So human sperm cells and egg cells will have 23 chromosomes.

A human liver cell is...

1. haploid (n)
2. diploid (n)
3. diploid (2n)
4. can be either haploid or diploid

Why do you think that mitosis is a suitable type of cell division for repairing tissues but meiosis is not?

At the end of mitosis you end up with:

1. 2 genetically identical daughter cells
2. 4 genetically identical daughter cells
3. 2 genetically different daughter cells
4. 4 genetically different daughter cells

Please order the four stages of mitosis

Prophase

Metaphase

Anaphase

Telophase

Interphase

DNA replication occurs during ...

1. telophase
2. interphase
3. anaphase
4. metaphase

Transcription and translation occur during ...

1. telophase
2. interphase
3. anaphase
4. metaphase

The part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells is called ...

1. cytokinesis
2. mitosis
3. metaphase
4. nuclear division

Which is NOT a function of mitosis?

1. Repair
2. Growth
3. Asexual reproduction
4. Sexual reproduction

Mitosis produces:

1. 2 haploid cells with 23 chromosomes each
2. 2 diploid cells with 23 chromosomes each
3. 2 diploid cells with 46 chromosomes each
4. 2 haploid cells with 46 chromosomes each
