1. cell membrane phospholipid bilayer that surrounds all cells and regulates what enters and leaves
(plasma mem- the cell
brane)
2. eukaryote A cell that contains a nucleus and membrane bound organelles
3. nucleoid A non-membrane-bounded region in a prokaryotic cell where the DNA is concen-
trated.
4. nucleus A part of the cell containing DNA and RNA and responsible for growth and
reproduction
, BIOL 204 Athabasca U- Midterm
5. prokaryote A unicellular organism that lacks a nucleus and membrane bound organelles
6. amyloplast Unpigmented plasids that store starch grains, abundent in cells of stems, tubers,
and seeds
7. anchoring junc- mechanically attaches adjacent cells to each other or to the basement membrane
tion
8. bacterial flagel- A ropelike structure built from actin proteins that, through rotary movements,
lum propels a bacterium through fluid.
9. 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.
, BIOL 204 Athabasca U- Midterm
10. cell wall A rigid layer of nonliving material that surrounds the cells of plants and some
other organisms.
11. centrosome A structure in animal cells containing centrioles from which the spindle fibers
develop.
12. chloroplast An organelle found in plant and algae cells where photosynthesis occurs
13. chromoplast a colored plastid other than a chloroplast, typically containing a yellow or orange
pigment.
, BIOL 204 Athabasca U- Midterm
14. crista (pl. cristae) the folds of the inner membrane of mitochondria. The site of the electron transport
chain
15. cytoskeleton A network of fibers that holds the cell together, helps the cell to keep its shape,
and aids in movement
16. endoplasmic extensive interconnected network of membranous channels called cisternae,
reticulum (rough some have ribosomes covering it and others don't.
or smooth)
