eukaryotes & prokaryotes
where are prokaryotic cells found in?
bacteria / single celled organisms
eukaryotes & prokaryotes
name the 3 subcellular structures that all eukaryotic cells contain.
nucleus
cytoplasm
cell membrane
eukaryotes & prokaryotes
name the 2 subcellular structures that all prokaryotic cells contain.
a single dna loop
plasmids
eukaryotes & prokaryotes
name the subcellular structures that all prokaryotic cells do NOT contain.
mitrochondia
nucleus
chloroplasts
eukaryotes & prokaryotes
what are plasmids? what do they do?
small rings of dna.
they move between cells to share genetic information.
eukaryotes & prokaryotes
which subcellular structure in prokaryotes cab replicate?
plasmids
eukaryotes & prokaryotes
which type of cell are unicellular, prokaryotes or eukaryotes?
prokaryotes
eukaryotes & prokaryotes
which one is bigger, eukaryotes or prokaryotes?
eukaryotes
microscopy
what are the 2 variables that matter the most when using microscopes?
resolution & magnification
microscopy
what does magnification tell us?
how many times an image is seen through a microscope compared to the actual object
microscopy
what does resolution tell us?
tell apart 2 or more objects that are close together
microscopy
what are the 2 types of microscopes?
light microscope & electron microscope
microscopy
what is the equation for magnification?
magnification= image size / object size
microscopy
what is the light microscope used to see?
cells
microscopy
what is the electron microscope used to see?
cells
subcelular structures & functions
