Cell type

The rat has animal eukaryotic cells. The palm tree has plant eukaryotic cells.

NUTRITION FUNCTION OF RAT

Nutrition function of the rat

Obtaining nutrients: They obtain nutrients with a mouth with teeth and tongue. They have a complex digestive tract.

Breathing: They take oxygen from the air by the lungs.

Circulation and excretion: They have a closed circulatory system with a heart. They use the kidneys and the anus.

NUTRITION FUNCTION OF RATS

Interaction function of the rat

Interaction with the environment: The rat goes to the rubbish in search of food.

Perception of information: They perceive the information by the eyes, ears, mouth, nose and skin.

Processing and coordination: When they perceive information, it´s carried on

through the nerves to the brain. Execution of responses: The information

is carried on to the muscles to produce reactions.

REPRODUCTION FUNCTION OF PALM TREE

Reproduction function of the rat The rats have a sexual reproduction. The sperm enters in the ovule.

NUTRITION FUNCTION OF PALM TREE

Nutrition of the palm tree

Obtaining nutrients: They perform the photosynthesis.

Respiration: They absorb oxygen through the stomata to get energy by the mitochondria

Substance distribution: They distribute the phloem sap throughout the plant.

Eliminating waste matter: They keep the waste substances in old leaves.

Interaction function of the palm tree

Interaction function of the palm tree

They move towards the sun to obtain solar energy. They move very slowly. This is a nastic movement called photonasty.

It also perform tropism. For example, the roots grow towards the earth using geotropism

Reproduction function of the

palm tree

Reproduction function of the palm tree

They have asexual reproduction. They reproduce through pollen.

Conclusion

Rats and palm trees are living things and they perform the three vital functions.

It is more evident when animals are performing the 3 vital functions than when plants are.
