BIO 101 EXAM 2 ASSESSMENT 2026 FULL
QUESTIONS AND CORRECT ANSWERS
GRADED A+
◉ 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?
