4. What are living things made of? Cells work together to carry out the seven life processes that are needed for an organism to stay alive. Other organisms are multicellular – they are made up of many types of cells. Can you think of some examples of unicellular and multicellular organisms? Some organisms are unicellular – they are made up of only one cell. Cells are the building blocks of life – they come in all shapes and sizes.

7. What is a cell? Animal and plant cells come in different shapes and sizes, but they all have three basic features. Plant cells also have some extra features that make them different to animal cells. cell membrane cytoplasm nucleus animal cell plant cell Most cells have three basic parts: the nucleus, cytoplasm and cell membrane. They may also contain other small structures or organelles, that perform specific jobs.

11. Functions of the organelles OrganelleFunction Cell surface membrane Controls what goes in and out of the cell. Keeps the cell together. CytoplasmJelly-like substance. Where the cell’s chemical reactions take place. NucleusContains the DNA. Controls the cell. Cell wallSupports the cell. Made out of cellulose. Cell vacuoleContains cell sap. Helps support the cell ChloroplastContain chlorophyll, a green pigment. Make the plants’ food by photosynthesis.
