BIOLOGY 101, EXAM 2
QUESTIONS WITH COMPLETE
AND ACCURATE ANSWERS.
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 pseudopods
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
