The place where a plant or animal lives is called its habitat.

Front 23

Herbivore:

Back 23

n animal that eats only plants.

Front 24

Haemoglobin:

Front 25

Herbivore:

Back 25

An animal that eats only plants.

Front 26

Implantation:

Back 26

The iris controls the amount of light entering the eye.

Front 29

Ligaments:

Back 29

Fibres that connect bone to bone.

Front 30

Front 33

Omnivore:

Back 33

An animal that eats plants and animals.

Front 34

Organ:

Back 34

A group of tissues working together e.g. heart.

Front 35

Ovulation:

Back 35

This is the release of an egg from an ovary.

Front 36

Phloem:

Back 36

This is a plant transport tissue. It transports food from where it is made to other parts of the plant.

Front 37

Photosynthesis:

Back 37

This is the process in which green plants make food.

Front 38

Phototropism:

Back 38

The growth of a plant in response to light.

Front 39

Placenta:

Back 39

The structure that binds the developing baby to the wall of the womb. It allows nutrients and waste to be exchanged.

Front 40

Pollination:

Back 40

This is the transfer of pollen from the anther of the stamen to the stigma of the carpel.

Front 41

Pollination:

Back 41

This is the transfer of pollen from the anther of the stamen to the stigma of the carpel.

Front 42

Pollution:

Back 42

This is where things such as oil, sewage, slurry, sulphur dioxide, nitrogen oxides and litter damage the environment.

Front 43

Back 43

A piece of equipment used to collect small animals.

Front 44
