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

Endoplasmic Reticulum - ANSWERS-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 - ANSWERS-protein synthesis
Smooth ER - ANSWERS-lipid synthesis
calcium ion storage
poison detoxification
Nucleolus - ANSWERS-nonmembranous structure involved in
production of ribosomes; a nucleus has one or more nucleoli
Chromatin - ANSWERS-material consisting of DNA and proteins;
visible in a dividing cell as individual condensed chromosomes
cell wall - ANSWERS-outer layer that maintains cell's shape and
protects cell from mechanical damage; made of cellulose, other
polysaccharides, and protein

Chloroplast - ANSWERS-photosynthetic organelle; converts energy of
sunlight to chemical energy stored in sugar molecules
central vacuole - ANSWERS-prominent organelle in older plant cells;
storage, breakdown of waste products, hydrolysis of macromolecules;
enlargement of vacuole major mechanism of plant growth.
