Functions of Parts of the cell
All living things are made up of cells. The structures of different types of cells are related to their functions.
Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant and algal cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Bacterial and yeast cells have different structures to animal and plant cells.
Dissolved substances pass into and out of cells by diffusion.
Function of cells which animal and plant cells have in common
|Nucleus||Contains genetic material, which controls the activities of the cell|
|Cytoplasm||Most chemical processes take place here, controlled by enzymes|
|Cell membrane||Controls the movement of substances into and out of the cell|
|Mitochondria||Most energy is released by respiration here|
|Ribosomes||Protein synthesis happens here|
Plant cells also have extra parts:
Extra parts of plant cells
|Cell wall||Strengthens the cell|
|Chloroplasts||Contain chlorophyll, which absorbs light energy for photosynthesis|
|Permanent vacuole||Filled with cell sap to help keep the cell [turgid: Having turgor; enlarged and swollen with water ]|
