Growth and Development

Human cells, most animal cells and plant cells have the following parts:

Cytoplasm - where most chemical reactions take place.

Nucleus - Contains genetic information

Ribsomes - Where protein synthesis takes place

A cell membrane - controls movement into and out of the cell.

Plant cells also have the following parts:

A cell wall - stengthens the cell

A permanent vacuole - helps support the cell

Chloroplasts - absorb light energy to make food.

Mitosis is the division of the body cells to produce new cells. Each new cell has...

Identical sets of chromosomes as the parent cell

The same number of chromosomes as the parent cell

The same genes as the parent cell

Mitosis occurs...

For growth

For repair

To replace old tissues.

To enable mitosis to take place, cells go through a cycle of growth and then division
