BIOL 204 Athabasca U- Midterm
with complete verified solutions
already graded A+
cell membrane (plasma membrane)
phospholipid bilayer that surrounds all cells and regulates what enters
and leaves the cell
eukaryote
A cell that contains a nucleus and membrane bound organelles
nucleoid
A non-membrane-bounded region in a prokaryotic cell where the DNA is
concentrated.
nucleus
A part of the cell containing DNA and RNA and responsible for growth and
reproduction
,prokaryote
A unicellular organism that lacks a nucleus and membrane bound
organelles
amyloplast
Unpigmented plasids that store starch grains, abundent in cells of stems,
tubers, and seeds
anchoring junction
mechanically attaches adjacent cells to each other or to the basement
membrane
bacterial flagellum
A ropelike structure built from actin proteins that, through rotary
movements, propels a bacterium through fluid.
capsule
A sticky layer that surrounds the cell walls of some bacteria, protecting
the cell surface and sometimes helping to glue the cell to surfaces.
, cell wall
A rigid layer of nonliving material that surrounds the cells of plants and
some other organisms.
centrosome
A structure in animal cells containing centrioles from which the spindle
fibers develop.
chloroplast
An organelle found in plant and algae cells where photosynthesis occurs
chromoplast
a colored plastid other than a chloroplast, typically containing a yellow or
orange pigment.
