Exam Questions and Correct Answers |
New Update
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.
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
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.
