Gen Biology
Cells Study Guide – (Ch 7)
Be able to
identify cell organelle structure and
function, including:
Ribosomes,
Rough ER, Smooth ER, Golgi Apparatus, Mitochondria,
Vacuoles, Centrioles, Lysosomes,
Peroxisomes, Vesicles, Nucleus, nucleoid region, Chloroplast,
Mitochondria, Flagella, Cillia, Cell Wall, Pili, Capsule, Cytoskeleton, etc.
For all of
these you should be able to distinguish between animal, plant and prokaryotic
cells (which possess which structures).
Be able to
trace the path of a protein through its production in the different organelles.
I mean the idea of nucleus->mRNA->Ribosome,
etc
You should
know what the fluid mosaic model is and be able to describe the cell membrane
components. What can travel through a phospholipid bilayer? What can’t?
Important processes:
You should
be able to distinguish and compare simple diffusion, osmosis, facilitated
diffusion, active transport and endo/exocytosis. How
are these processes similar to one another? How do they differ? When would one
be more appropriate than another?
You should
understand the effects of solute concentrations on cells. For example what
happens when a cell is placed in distilled water verses in salty water? How is
this different for different cell types?
Other Stuff:
By now you
should be familiar with the “rechargeable battery” analogy of ATP and ADP.
You should
be familiar with limitations on cell size as well as knowing the approximate
size ranges of the three domains. Be familiar with the “pizza guy” and "Interstate
vs streets" analogy for transport and how shape is important to cell area.
Be able to discuss surface area
and how
those measurements relate to cell size.
