Biology

Cells are too small to see with the naked eye. Using a light microscope helps us to see and draw cells.

Animal and plant cells share some features but not others.

Different parts of animal and plant cells have different functions.

Controls what enters and leaves the cell.

Place where lots of chemical reactions (photosynthesis) take place.

Stores information (in DNA) and controls what happens in the cell.

Release energy from food (glucose) by aerobic respiration.

Made from cellulose and gives rigid support to the cell.

Inflates the cell like air pumped into a tyre and provides support to the cell.

Contains green chlorophyll that changes sunlight energy into glucose food energy.

Diffusion is one of the ways that substances enter and leave cells.

Unicellular organisms have just one cell.

Bone cells in the skeletal system.

Blood cells in the transport system.

Nerve cells in the nervous system.

Sperm cells in the reproductive system.

Sexual reproduction in humans involves males and females.

Males produce sperm cells in the testes. Females produce egg cells in the ovary.

Females have a menstrual cycle lasting for about 28 days. This is called menstruation.

Gestation is the process of the embryo developing in the womb.

Some flowers are insect pollinated e.g. a rose
