Three cell parts found in all cells? - ANSWER DNA, plasma membrane, and cytoplasm or ribosomes
What is the cell theory? - ANSWER The cell is the basic unit of life, all living things are made up of one or
more cells, and all cells come from the reproduction of other cells
Cells that do not have a nucleus are: - ANSWER prokaryotes
DNA in bacterial/prokaryotic cells forms a: - ANSWER circle
DNA in eukaryotic cells are: - ANSWER linear
Why are cells small? - ANSWER Cells do not get very large because the surface area to volume ratio must
be high to allow for the ready exchange of materials in and out of the cell
What three cell parts are found ONLY in plant cells? - ANSWER cell wall, chloroplasts, and the
large/central vacuole
What is Endosymbiosis? - ANSWER The theory that some prokaryotic cells engulfed other prokaryotic
cells thus forming membrane-bound structures (like mitochondria or chloroplasts) and ultimately giving
rise to eukaryotic cells
What is the organelle site of the reaction called CELLULAR RESPIRATION in eukaryotic cells? - ANSWER
Mitochondria
What do you call the site of PROTEIN and LIPID SYNTHESIS in eukaryotic cells is an ENDOMEMBRANE
SYSTEM? - ANSWER the Endoplasmic Reticulum

What can you find in the nucleus? - ANSWER the nucleolus and DNA
How can you distinguish between the ROUGH E.R. and the SMOOTH E.R.? - ANSWER the presence of
RIBOSOMES in the rough E.R.
What are the three structures that enable cells to move? - ANSWER cilia, flagella, and psuedopods
What is found within the CHLOROPLASTS and is the site of PHOTOSYNTHESIS? - ANSWER thylakoids
What are the folds within the MITOCHONDRIA called? - ANSWER cristae
What are cytoplasmic bridges found between PLANT cells? (holes in the CELL WALL) - ANSWER
plasmodesmata
What are the cytoplasmic bridges found between ANIMAL cells? (openings in the CELL MEMBRANES) -
ANSWER gap junctions
Which organelle contains DIGESTIVE ENZYMES? - ANSWER the lysosome
The lysosome is produced by the pinching off of portions of the membranes of the: - ANSWER Golgi
bodies/apparatus
What is the site of PROTEIN SYNTHESIS? - ANSWER Ribosomes
What is the largest CYTOSKELETON component? - ANSWER the microtubules
What are the structures involved in CELL MOVEMENT that are made up of "9+2" microtubules? -
ANSWER Cilia and Flagella
