1. cell structure Flashcards
what are the 4 types of cells?
plant, animal, fungus, bacteria
what organelles are found in a plant cell?
cytoplasm, cell membrane, cell wall, ribosomes, nucleus, mitochondria, vacuole, chloroplasts
what organelles are found in an animal cell?
cytoplasm, cell membrane, nucleus, ribosomes, mitochondria,
what organelles are found in a fungal cell?
cytoplasm, cell membrane, cell wall, nucleus, ribosomes, mitochondria, vacuole
what organelles are found in a bacterium cell?
cytoplasm, cell membrane, bacteria DNA, ribosomes, cell wall, plasmid
what is the function of the cytoplasm?
site of cell reactions
what is the function of the cell membrane?
controls entry and exit of molecules to cells
what is the function of the nucleus?
contains genetic information/DNA controls cell activities
what is the function of ribosomes?
sites of protein synthesis
what is the function of the mitochondria?
site of aerobic respiration
what is the function of the cell wall?
gives the cell structure and support
what is the function of the vacuole?
contains cell sap
what is the function of the chloroplasts?
contains chlorophyll - traps light for photosynthesis
what is the function of plasmids?
additional rings of DNA
what are plant cell walls made of?
cellulose fibers - they are strong, rigid and slightly elastic to resist the uptake of water, maintain the shape and support the cell.
