Differences in the shape, size, and structures of cells are adaptations.

A specialised cell has adaptations that allow it to carry out a specific function.

The function of a cell is its job or its role within an organism.

Specialised cells are adapted for their functions

Science

The common processes of all living organisms

Observing cells with a light microscope

Preparing and observing a microscope slide

Animal cell structures and their functions

Plant cell structures and their functions

Multicellular and unicellular organisms

Pupils will learn about bones and muscles as examples of tissues made of cells.

In Y2 of primary science, pupils learned about some processes that happen in all living things (and do not happen in things that are dead or have never been alive).

This unit explores cell structures, their functions, and differences between plant and animal cells. It includes adaptations of unicellular organisms and the organisation of multicellular organisms. Skills in using safe techniques, recording data, and evaluating methods in lab work are developed.

Cells

Cells can vary in shape and the structures they contain. These differences are called {{}}.

Which of the following adaptations would help a muscle cell carry out its function?

Elongated shape, to give a large area, to absorb water.

Many chloroplasts to trap light, to make the plant's food.

Match each cell type to the correct description of its adaptation.

How are red blood cells adapted to carry oxygen?

Which word best describes a cell that is adapted to carry out its job?

A {{}} organism is made up of many different cells.

Starting with the smallest, put these in size order to describe the organisation in a multicellular organism.

Choose the organs that are found in plants.

Which of these types of tissue could be found in some animal organs?

Multicellular organisms have organs that are made up of more than one type of {{}}.

Unicellular organisms are adapted to live as single cells, and can have different structures to help them {{}} in their surroundings.
