cell structure Flashcards
What is the function of the cell membrane?
controls what enters and leaves the cell
what is the function of the cytoplasm?
site of chemical reactions in the cell
what is the function of the nucleus in an animal cell?
controls the cells activities
where in an animal cell does protein synthesis occur?
Ribosomes
what is the function of vacuole in a plant cell?
stores cell sap and maintains cell shape
what is the function of the cell wall in plant, bacterial and fungal cells?
provides support and gives structure to the cell
where in the cell does aerobic respiration occur?
Mitochondria
which cell structure is the site of photosynthesis?
chloroplast
give three structures that are found in both plant and animal cells
nucleus cell membrane ribosomes cytoplasm mitochondria
give two structural differences between plant and animal cells
plant cells have a cell wall whereas animal cells do not
plant cells have a cytoplasm whereas animal cells do not
plant cells have a vacuole whereas animal cells do not
give two differences between an animal and a bacterial cell
bacterial cell has a plasmid which an animal cell does not
bacterial cell has a cell wall which an animal cell does not
bacterial cell has circular chromosomes which animal cells do not have
give a difference between a plant and fungal cell
plant cell wall is made of cellulose and fungal cells cell wall isn’t made of cellulose
what substance is the main component of pant cell walls?
cellulose
why do scientists use a stain when viewing cells under a microscope?
as stains enable us to see organelles more clearly when viewing under a microscope
what would the overall magnification be if the…
a) x40 objective lens was used to view cells?
b) x10 objective lens was used to view cells?
a) 400
b) 100
