stores genetic information, controls the activities of a cell.
what is cytoplasm & the function
jelly-like substance, composed of water and dissolves solutes. supports the internal cell, site of many chemical reactions e.g anaerobic respiration
what is the function of mitochondria
site of aerobic respiration.
do cells with high rates of metabolism have significantly higher or lower numbers of mitochondria
higher
what is the function of ribosomes & where are they found
site of protein synthesis, found in the cytoplasm
what is the function of the cell membrane
holds the cell together, controls what substances goes in and out of the cell, separates the inside of the cell from the outside
name the 8 sub-cellular structures in a plant
nucleus, mitochondria, permanent vacuole, ribosomes, cytoplasm, chloroplasts, cell wall, cell membrane
what is the function of a cell wall (2)
provides support and protection for the cell, helps regulate the exchange of materials between the cells and it’s environment
what is the function of chloroplasts
site of photosynthesis, which is required to make glucose for energy for the plant
what is the function of the permanent vacuole
filled with cell sap to keep the cell turgid, filled with water
