plasma membrane - (ANSWER)The membrane at the boundary of every cell that
acts as a selective barrier, thereby regulating the cell's chemical composition.
Ribosomes - (ANSWER)complexes that make proteins; free in cytosol or bound to
rough ER or nuclear envelope
Golgi apparatus - (ANSWER)active in synthesis, modification, sorting, and
secretion of cell products
Lysosome - (ANSWER)digestive organelle where macromolecules are hydrolyzed,
and autophagy
Mitachondrion - (ANSWER)organelle where cellular respiration occurs and most
ATP is generated
Cytoskeleton - (ANSWER)reinforces cell's shape; functions in cell movement;
components are made of protein. Includes: Microfilaments, Intermediate
filaments, Microtubules.
, 2
Endoplasmic Reticulum - (ANSWER)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 - (ANSWER)protein synthesis
Smooth ER - (ANSWER)lipid synthesis
calcium ion storage
poison detoxification
Nucleolus - (ANSWER)nonmembranous structure involved in production of
ribosomes; a nucleus has one or more nucleoli
Chromatin - (ANSWER)material consisting of DNA and proteins; visible in a
dividing cell as individual condensed chromosomes
cell wall - (ANSWER)outer layer that maintains cell's shape and protects cell from
mechanical damage; made of cellulose, other polysaccharides, and protein
Chloroplast - (ANSWER)photosynthetic organelle; converts energy of sunlight to
chemical energy stored in sugar molecules
, 3
central vacuole - (ANSWER)prominent organelle in older plant cells; storage,
breakdown of waste products, hydrolysis of macromolecules; enlargement of
vacuole major mechanism of plant growth.
