BIOS251 Exam 2 Review Cell
Theory and Tissue Types 2026
Exam Questions and Correct
Answers | New Update
Principles of Cell Theory - 🧠 ANSWER ✔✔The smallest structure capable
of carrying out life processes; every organism is made up of one or more
cells; cells can only form from pre-existing cells.
Prokaryotic cells - 🧠 ANSWER ✔✔Cells without an organized nucleus.
,Eukaryotic cells - 🧠 ANSWER ✔✔Cells with an organized and well defined
nucleus.
Plasma (cell) membrane - 🧠 ANSWER ✔✔Separates internal and external
environments.
DNA - 🧠 ANSWER ✔✔Genetic material that controls an organism's
composition and replicates the cell.
Cytoplasm - 🧠 ANSWER ✔✔All the fluid and components between the
nucleus and the cell membrane, including the cytosol and cytoskeleton.
Cytosol - 🧠 ANSWER ✔✔The liquid portion of the cytoplasm.
Organelles - 🧠 ANSWER ✔✔Specialized structures within a cell that
perform distinct processes.
Ribosomes - 🧠 ANSWER ✔✔The site of protein synthesis.
Cytoskeleton - 🧠 ANSWER ✔✔Intracellular support used in cell movement
and moves organelles.
Gamete cells - 🧠 ANSWER ✔✔Cells used for reproduction (sperm and
ovum) that replicate via meiosis.
, Somatic cells - 🧠 ANSWER ✔✔All other cells in the body that replicate via
mitosis.
Functions of the cell membrane - 🧠 ANSWER ✔✔Serves as a barrier,
anchors the cytoskeleton, shapes the cell, allows communication, moves
essential molecules in, and removes waste.
Phospholipid bilayer - 🧠 ANSWER ✔✔The structure that makes up the cell
membrane, consisting of hydrophilic heads and hydrophobic tails.
Transmembrane proteins - 🧠 ANSWER ✔✔Proteins that cross the width of
the membrane touching both internal and external surfaces.
Peripheral proteins - 🧠 ANSWER ✔✔Proteins only found on one surface of
the membrane.
Cholesterol - 🧠 ANSWER ✔✔Creates the fluid mosaic model that gives the
cell both structure and flexibility.
Integral proteins - 🧠 ANSWER ✔✔Proteins that travel the entire width of the
membrane touching both internal and external surfaces.
Channel proteins - 🧠 ANSWER ✔✔Proteins that allow ions to cross the
membrane from one side to another.
