All animals and plants are made of cells. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Note that cells may be specialised to carry out a particular function.

Dissolved substances pass into and out of cells by diffusion. Water passes into and out of cells by osmosis.

Animal and plant cells

Function of cells which animal and plant cells have in common

partfunction
nucleuscontains genetic material, which controls the activities of the cell
cytoplasmmost chemical processes take place here, controlled by enzymes
cell membranecontrols the movement of substances into and out of the cell
mitochondriamost energy is released by respiration here
ribosomesprotein synthesis happens here

Plant cells also have extra parts:

Extra parts of plant cells

partfunction
cell wallstrengthens the cell
chloroplastscontain chlorophyll, which absorbs light energy for photosynthesis
permanent vacuolefilled with cell sap to help keep the cell turgid [turgid: Having turgor; enlarged and swollen with water ]

Make sure you can label diagrams of animal and plant cells, like these:

both cells have a membrane on the outside, and cytoplasm and a nucleus inside. In the plant only are the cell wall, vacuole, and chloroplast.
