Function of Cell Membrane?
found in animal and plant cells
Controls what substances can get in and out of the cell
Function of a Cytoplasm?
found in plant and animal cells
Jelly-like substance, where chemical reactions happen. In plant cells there’s a thin lining, whereas in animal cells most of the cell is cytoplasm.
Function of a Nucleus?
found in plant and animal cells
Contains genetic material, which controls the activities of the cell
Function of Mitochondria?
found in plant and animal cells
Most energy is released by respiration here
Function of Ribosomes?
found in plant and animal cells
Protein synthesis happens here
Function of cell wall?
found in plant cells
Strengthens the cell
Function of Chloroplasts?
found in plant cells
Contains chlorophyll, which absorbs light energy for photosynthesis
Function of Vacuole?
found in plant cells
Filled with cell sap to help keep the cell turgid
What is the order of organisation?
