QUIZ #3 - Anatomy and Physiology

Phospholipid bilayer; selectively allows molecules into and out of a cell.

plasma membrane

Region that produces subunits of ribosomes

nucleolus

large central structure that functions as the control center of the cell.

nucleus

Structure that maintains the cell shape and assists movement of cell parts

cytoskeleton

short cylinders of microtubules that aid in cell division

centrioles

particles that carry out protein synthesis

ribosomes

vacuole that digests macromolecules and cell parts

lysosomes

Double membrane that encloses the nucleus

nuclear envelope

semi-fluid matrix outside the nucleus that contains the organelles

cytoplasm

membrane bond sac that stores and transports substances

vesicle

organelle that carries out cellular respiration producing ATP molecules for energy

mitochondria

Tubules that transport substances in the cell covered with ribosomes

rough endoplasmic reticulum

defuse threads containing DNA and protein found in the nucleus

chromatic

processes, packages, and secretes modified cell products

golgi apparatus

tubules that transport materials through a cell which lack ribosomes and synthesize lipids

smooth endoplasmic reticulum

short hair-like projections that move materials along the surfaces of cells

cilia

Cylinders of protein molecules present in the cytoplasm that move organelles and cells

microtubules
