BIO 105 EXAM 2 MOCK TEST WITH ANSWER
RATIONALES 2026
◉ Eukaryotic.
Answer: A cell characterized by the presence of a nucleus and other
membrane-bound organelles. Eukaryotes can be unicellular
(protists) or multicellular (fungi, plants and animals).
◉ microvilli function.
Answer: increase surface area for absorption and secretion
◉ microvilli structure.
Answer: tubular extensions of the plasma membrane; contain a
bundle of actin filaments
◉ microvilli location.
Answer: projections of the plasma membrane
◉ cell wall function.
Answer: provides support and protection
◉ cell wall structure.
,Answer: cellulose
◉ cell wall location.
Answer: outside the cell membrane
◉ Plasma membrane function.
Answer: encloses cell contents; regulates movement of materials in
and out of cell; helps maintain cell shape; communicates with other
cells (also present in prokaryotes)
◉ Plasma membrane structure.
Answer: phospholipid bilayer
◉ plasma membrane location.
Answer: External boundary of the cell
◉ Cytoplasm function.
Answer: Where the organelles reside
◉ cytoplasm structure.
Answer: the clear, gelatinous fluid inside a cell
, ◉ cytoplasm location.
Answer: between the cell membrane and the nucleus
◉ nucleoplasm function.
Answer: circulates materials through the nucleus
◉ nucleoplasm structure.
Answer: gel-like fluid consisting of water, nucleic acids, and proteins
◉ nucleoplasm location.
Answer: contained within the nuclear envelope
◉ Nucleus function.
Answer: Information in DNA is transcribed in RNA synthesis;
specifies cell proteins
◉ nucleus structure.
Answer: Largest organelle. Surrounded by the nuclear envelope;
contains fluid nucleoplasm, nucleoli, and chromatin. CELLS DNA
◉ nucleus location.
Answer: center of the cell
