Organelles Quiz I

Terms of organelles for anatomy and physiology quiz

QuestionAnswer
Cell The basic biological unit of living organisms, containing a nucleus and a variety of organelles enclosed by a limiting membrane
Centrioles A minute body found near the nucleus of the cell; active in cell division
Chromatin The structures in the nucleus that carry the hereditary factors or genes
Chromosomes Barlike bodies of tightly coiled chromatin; visible during cell division
Cillia Tiny, hairlike projections on cell surfaces that move in a wavelike manner
Cytoplasm The substance of a cell other than that of the nucleus
Cytoskeleton Cellular skeleton contained within a cell's cytoplasm
Cytosol Liquid found inside the cell
DNA Nucleic acid found in all living cells; carries the organism's hereditary information
Flagella Long, whiplike extensions of the cell membrane of some bacteria and sperm that are used to propel the cell
Golgi Apparatus Stack of membranous sacs associated with swarms of tiny vesicles, it is the traffic director for cellular proteins
Inclusion Chemical substances that may or may not be present depending on cell type; non-functioning
Interstitial fluid Fluid between the cells
Lysosomes Organelles that originate from the Golgi Apparatus and contain strong digestive enzymes
Microvilli The tiny projections on the free surfaces of some epitelial cells; increase surface area for absorption
Mitochondria The rod-like cytoplasmic organelles responsible for ATP generation for cellular activities
Nuclear membrane Also known as the nuclear envelope, this is a double lipid bilayer that surrounds the genetic material and nucleolus
Nucleoli Small spherical bodies in the cell nucleus; function in ribosome synthesis
Nucleoplasm the substance of a cell nucleus
Nucleus A dense central body in most cells containing the genetic material of the cell
Organelles Specialized structures in a cell that perform specific metabolic functions
Perixosomes Membranous sacs containing powerful oxidase enzymes that use molecular oxygen to detoxify a number of harmful or poisonous susbtances
Plasma (cell) Membrane Membrane that encloses cell contents
Ribosomes Cytoplasmic organelles at which proteins are synthesized
Rough ER Studded with ribosomes, essentially all building materials of cellular membranes are formed either in it or on it
Smooth ER Functions in cholesterol synthesis and breakdown, fat metabolism, and detoxification of drugs
