cell structures and functions Flashcards
a unicellular organism has
1 single cell
a multicellular organism is
made up of many cells
the ultrastructure of a cell is
its fine structure revealed at high magnification
the ultrastructure of an animal cell includes
cell membrane, nucleus, cytoplasm, mitochondrion and ribosomes
the ultrastructure of a plant cell includes
cell wall, cell membrane, nucleus, cytoplasm, vacuole, chloroplasts, mitochondrion and ribosomes
the ultrastructure of a fungal cell includes
cell wall, cell membrane, nucleus, cytoplasm, vacuole, mitochondrion and ribosomes
the ultrastructure of a bacterial cell includes
cell wall, cell membrane, cytoplasm, plasmids and ribosomes
the nucleus contains
genetic material
the nucleus controls
the cell’s activities
the cell membrane controls
what enters/exits the cell
cell organelles are
compartments found in the cytoplasm and are the site of chemical reactions
cell organelles include
nuclei, mitochondrion and chloroplasts
…….. cells don’t contain organelles
bacterial
the cell wall is for
support and prevents cells from bursting
plant cell walls are made of
cellulose
fungal and bacterial cell walls are made of
different materials
the vacuole stores
a watery solution of salts and sugars (cell sap) and helps support the cell
chloroplasts contain
chlorophyll
chloroplasts are the
site of photosynthesis
mitochondria are the
site of aerobic respiration
ribosomes are the
site of protein synthesis
in bacterial cells, plasmids hold
some of the genetic material (DNA) of the cell
cells can be magnified using
a microscope
bacterial cells can be cultures using
petri dishes
