General Biology- Cell Structure and
Function Questions with complete
solution 2025/2026
Mitochondria - correct answer ✔Powerhouse of the cell; site of ATP
Microtubules - correct answer ✔Support the shape of an entire cell; make up cilia, flagella, and
centrioles
Cell membrane - correct answer ✔Also called the plasma membrane; semipermeable barrier made of
two layers of phospholipids
Lysosomes - correct answer ✔Bags of enzymes used to digest particles and bacteria; "garbage men" of
the cell; they work in conjunction with vacuoles
Nucleus - correct answer ✔Control center of the cell; contains nucleolus and DNA; location where
ribosomes are formed
Rough Endoplasmic Reticulum - correct answer ✔External surface is studded with ribosomes;
membranous structure that synthesizes protein; acts as a transport system for newly formed proteins
Vacuoles - correct answer ✔Form from a piece of membrane breaking loose from cell membrane; store
substances; storage sacs; plant cells have a single large one; Animals have many smaller ones
Chloroplasts - correct answer ✔Sites for photosynthesis; found only in plant cells; contain chlorophyll;
location where photosynthesis occurs
Cilia and Flagella - correct answer ✔Locomotive structures made up of microtubules
