Living things Where plants and animals align

What’s alive We are surrounded by living and non-

living things. All animals and plants are living things

and biology is the study of these living things.

A cat playing with a ball is obviously living.

You think of some living and non living characteristics…

Respiration It is the release of energy by a chemical

reaction All living things exchange gases with

their environment. Animals take in oxygen and breathe out

carbon dioxide. Plants take in _________ and release __________ .

Nutrition Taking in food: Nutrition gives living things the energy and materials they need to move and make new cells( to grow, reproduce and repair).

What is our nutrition?

Excretion Waste body chemicals are poisonous

and the body must get rid of them.

Growth & Development Living things get bigger and more

complex with time.

Sensitivity Living things react to changes around

them. We react to touch, light, heat, cold and sound, as do other living things.

Just in case you thought plants don’t move think again! Watch to the movie below.

(They are sensitive to sunlight)

Reproduction All living things produce young. Humans make babies, cats produce

kittens and pigeons lay eggs. Plants also reproduce. Many make seeds

which can germinate and grow into new plants.

Movement All living organisms show movement of one

kind or another. All living organisms have internal movement,

which means that they have the ability of moving substances from one part of their body to another.

Some living organisms show external movement as well - they can move from place to place by walking, flying or swimming

Now to the difference between plants and animals… One of the main difference

between plants and animals is FOOD.

Plants are different from animals because they can make their own food through the process of PHOTOSYNTHESIS.

Therefore the internal structure of plants are different to those of animals.

What other differences can you think of?

Further classification… Classification does not stop there. We

have seen plants and animals have some distinct differences, however we are considered animals so does that mean we have the exact same features of a cat? NO, so plants and animals are further

classified…

Homework Task Research at least 4 differences between

plants and animals. Animals are further classified into

reptiles, mammal and what other groups?

Give 3 reasons why we can not live without plants.
