cell biology Flashcards
what can you see on light microscope
the outline of the cell, sometimes the nucleus
what can you see on electron microscope
allow you to visualise finer details- organelles.
due to there greater RESOLVING POWER and HIGHER RESOLUTION
what is the equation for magnification
MAGNIFICATION= image size/ object cell size (cm or mm)
how big are cells
a few MICROMETERS (μm)long
how do you convert μm to mm
by dividing by 1000
how do you get from mm to μm
by multiplying by 1000
what type of cell is a animal cell
eukaryotic cell
what type of cell is bacteria
prokaryotic cell
where are prokaryotic’s DNA found
in the plasmid
functions of cell membrane in plant and animal
semi-permeable, controls what enters and leaves-
function of cell wall in plant cell
the cell wall (cellulose) provides rigid structure
function of mitochondria
the mitochondria is where respiration takes place
function of nucleus
contains DNA
function of ribosomes
where protein synthesis
what organelle does plant cell have that animal cell doesn’t
chloroplast, cell wall , permanent vacuole ( stores sap)
