VERIFIED ANSWERS RATED 100%
CORRECT
Three cell parts found in all cells? - correct answer ✔✔DNA, plasma membrane, and cytoplasm
or ribosomes
What is the cell theory? - correct 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: - correct answer ✔✔prokaryotes
DNA in bacterial/prokaryotic cells forms a: - correct answer ✔✔circle
DNA in eukaryotic cells are: - correct answer ✔✔linear
Why are cells small? - correct 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? - correct answer ✔✔cell wall, chloroplasts,
and the large/central vacuole
What is Endosymbiosis? - correct 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? -
correct answer ✔✔Mitochondria
What do you call the site of PROTEIN and LIPID SYNTHESIS in eukaryotic cells is an
ENDOMEMBRANE SYSTEM? - correct answer ✔✔the Endoplasmic Reticulum
What can you find in the nucleus? - correct answer ✔✔the nucleolus and DNA
How can you distinguish between the ROUGH E.R. and the SMOOTH E.R.? - correct answer
✔✔the presence of RIBOSOMES in the rough E.R.
What are the three structures that enable cells to move? - correct answer ✔✔cilia, flagella, and
psuedopods
What is found within the CHLOROPLASTS and is the site of PHOTOSYNTHESIS? - correct answer
✔✔thylakoids
What are the folds within the MITOCHONDRIA called? - correct answer ✔✔cristae
Which organelle contains DIGESTIVE ENZYMES? - correct answer ✔✔the lysosome
What are cytoplasmic bridges found between PLANT cells? (holes in the CELL WALL) - correct
answer ✔✔plasmodesmata
What are the cytoplasmic bridges found between ANIMAL cells? (openings in the CELL
MEMBRANES) - correct answer ✔✔gap junctions
The lysosome is produced by the pinching off of portions of the membranes of the: - correct
answer ✔✔Golgi bodies/apparatus
