We classify living things into different groups .
We identify similarities and group similar things together
ANIMALS
Feed on other living things
Can move
Can be oviparous or viviparos
Have senses
Plants Produce their own food. Can't move from one place to another, but can move towards light or water. Plants are born from seeds or Spores
Fungi Feed on other living things that are decomposing. Can't move. One example is mould. More similar to animals than plants.
Other organisms Algae produce their own food but have different parts to plants. One example is Seaweed Bacteria are very small organisms. We can only see them under a microscope.
EXERCISE 3
Classify these living things: toadstool, grass, potato, butterfly, salmonella. You can use the internet to help you
EXERCISE 4
what grows on food when we leave it for a long time? How do we classify it?
All living things carry out these life processes: nutrition. reproduction and interaction. Let's have a look at how plants and animals carry out these life processes.
Living things obtain nutrient from food.nutrients help them to grow and function properly. Animals do not Make Their own food. Some eat meat, eat some plants and some eat meat and plants. Plants use sunlight water and nutrients from the soil to Make Their own food.
Reproduction Living things reproduce. Reproduction means making new living things. Some animals give birth to live young and others lay eggs. Most plants reproduce by making seeds that grow into new plants. Some produce spores.
Interaction Living things interact. Moving, touching and communicating are examples of interaction. Animals move, communicate and react to the world around them. Some animals live in groups and some animals live alone. Plants also react to their environment. They grow towards the light and their roots grow towards water. Some plants open and close, and some plants can climb
Plants have similarities and differences Living things from the same group have similarities and differences. Identifying these helps us to classify living things from the same group into different subgroups One way of classifying plants is by looking at their stems. This helps us to classify them into three subgroups: grasses, bushes and trees.
Grasses have a soft stem They are thin, flexible and usually short. Wheat is a grass. It has a long stem and many kernels at the end of each stem. We make bread from wheat.
Bushes have woody stems with low branches. They are taller than grasses and live longer. The blackberry bush has lots of long branches. These branches have thorns. The fruit is called the blackberry.
Trees have a thick, woody stem called a trunk. The branches grow out from the trunk, high above the ground. Deciduous trees lose all their leaves in autumn. Oak trees are deciduous. Evergreen trees produce leaves all year round. Pine trees are evergreen.
Amazing changes The first living things appeared on our planet over 2000 million Can you imagine what these living things looked like? years ago! over time living things have changed and evolved. This has created the variety of life on our planet today. Look at the incredible plants and animals in the pictures below. Read about how they have changed over time to adapt to their environment.
Brown bears have adapted to low temperatures by hibernating during the coldest months of the year.
Cactuses have adapted to have thick skin so they don't lose water in hot and dry environments
Stick insects have adapted to look like their environment so other animals can't see them.
