BIOL 1201 EXAM 1 (GREGG) QUESTIONS
AND ANSWERS 2026 VERIFIED.
Plasma membrane - ANS The membrane at the boundary of every cell that acts as a selective
barrier, thereby regulating the cell's chemical composition.
Ribosomes - ANS complexes that make proteins; free in cytosol or bound to rough ER or
nuclear envelope
Golgi apparatus - ANS active in synthesis, modification, sorting, and secretion of cell products
Lysosome - ANS digestive organelle where macromolecules are hydrolyzed, and autophagy
Mitachondrion - ANS organelle where cellular respiration occurs and most ATP is generated
Cytoskeleton - ANS reinforces cell's shape; functions in cell movement; components are
made of protein. Includes: Microfilaments, Intermediate filaments, Microtubules.
Endoplasmic Reticulum - ANS 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 - ANS protein synthesis
Smooth ER - ANS lipid synthesis
calcium ion storage
poison detoxification
Nucleolus - ANS nonmembranous structure involved in production of ribosomes; a nucleus
has one or more nucleoli
Chromatin - ANS material consisting of DNA and proteins; visible in a dividing cell as
individual condensed chromosomes
cell wall - ANS outer layer that maintains cell's shape and protects cell from mechanical
damage; made of cellulose, other polysaccharides, and protein
Chloroplast - ANS photosynthetic organelle; converts energy of sunlight to chemical energy
stored in sugar molecules
central vacuole - ANS prominent organelle in older plant cells; storage, breakdown of waste
products, hydrolysis of macromolecules; enlargement of vacuole major mechanism of plant
growth.
Part complete
The innermost electron shell of an atom can hold up to _____ electrons. - ANS 2
Which of these relationships is true of an uncharged atom? - ANS The number of protons is
equal to the number of electrons
