The cell membrane surrounds the cell and controls what substances enter and leave the cell.

The cytoplasm is the jelly-like substance inside a cell where the chemical reactions of the cell take place.

The nucleus contains DNA, which stores information that controls the activities of the cell.

Mitochondria use food and oxygen as fuel to provide energy for the cell in a process called cellular respiration.

Scientists use models as simpler representations of complex things and ideas.

Animal cell structures and their functions

Science

The common processes of all living organisms

Observing cells with a light microscope

Preparing and observing a microscope slide

Plant cell structures and their functions

Multicellular and unicellular organisms

Specialised cells are adapted for their functions

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.
