Biol 1201 Exam 1 (gregg) Questions and
Answers 100% Pass
plasma membrane - ✔✔The membrane at the boundary of every cell that acts as a
selective barrier, thereby regulating the cell's chemical composition.
Ribosomes - ✔✔complexes that make proteins; free in cytosol or bound to rough ER or
nuclear envelope
Golgi apparatus - ✔✔active in synthesis, modification, sorting, and secretion of cell
products
Lysosome - ✔✔digestive organelle where macromolecules are hydrolyzed, and
autophagy
Mitachondrion - ✔✔organelle where cellular respiration occurs and most ATP is
generated
Cytoskeleton - ✔✔reinforces cell's shape; functions in cell movement; components are
made of protein. Includes: Microfilaments, Intermediate filaments, Microtubules.

, Endoplasmic Reticulum - ✔✔network of membranous sacs and tubes; active in
membrane synthesis and other synthetic and metabolic processes; has rough (ribosome-
studded) and smooth regions
Rough ER - ✔✔protein synthesis
Smooth ER - ✔✔lipid synthesis
calcium ion storage
poison detoxification
Nucleolus - ✔✔nonmembranous structure involved in production of ribosomes; a
nucleus has one or more nucleoli
Chromatin - ✔✔material consisting of DNA and proteins; visible in a dividing cell as
individual condensed chromosomes
cell wall - ✔✔outer layer that maintains cell's shape and protects cell from mechanical
damage; made of cellulose, other polysaccharides, and protein
Chloroplast - ✔✔photosynthetic organelle; converts energy of sunlight to chemical
energy stored in sugar molecules
central vacuole - ✔✔prominent organelle in older plant cells; storage, breakdown of
waste products, hydrolysis of macromolecules; enlargement of vacuole major
mechanism of plant growth.
