Biology Flashcards
what is a cell membranes function in a animal cell?
the cell membrane separates the interior of the cell from the environment outside. the membrane is selectively permeable. this means that it has control over which substances enter and exit the cell.
what is the nucleus function in a animal cell?
the nucleus is the control centre of the cell. it contains chromosomes, which contain the cells genetic material.
what is the ribosomes function in a animal cell?
ribosome are responsible for synthesising (making) proteins.
what is the function of mitochondria in a animal cell?
mitochondria are the organelles where aerobic respiration happens.
what is aerobic respiration?
aerobic respiration is a process that uses sugar and oxygen to release energy.
what is cytoplasms function in a animal cell?
cytoplasm is a jelly like fluid that fills the cell. cytoplasm is where most of the cells chemical reactions take place.
what is the permanent vacuoles function in a plant cell?
a permanent vacuole is a fluid filled sac that stores water. it is enclosed in a membrane. it makes up as much as 90% of the plant cells volume.
what is the function of chloroplasts in a plant cell?
chloroplasts contain chlorophyll, which is needed for the process of photosynthesis.
what’s the cell walls function in a plant cell?
the cell wall surrounds the cell and is made of cellulose. the cell wall increases the structural strength of the cell.
