AP Biology - Cell Organelle Flashcards
Terms in this set (36)
The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
nuclear envelope/membrane with pores
(nucleus) The double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells.
(nucleus) Thread-like structures located inside the nucleus of animal and plant cells. Passed form parents to offspring.
(nucleus) A complex of DNA and protein that forms chromosomes within the nucleus of eukaryotic cells.
(nucleus) The nuclear subdomain that assembles ribosomal subunits in eukaryotic cells.
Includes the nuclear membrane, the endoplasmic reticulum, the golgi apparatus, lysosomes, vesicles, endosomes, and the cell membrane.
(endomembrane) A small structure consisting of fluid enclosed by a lipid bilayer membrane.
rough endoplasmic reticulum
(endomembrane) A network of tubular membranes within the cytoplasm of the cell with a surface studded with ribosomes.
smooth endoplasmic reticulum
(endomembrane) A network of tubular membranes within the cytoplasm of the cell with a smooth surface.
(endomembrane) A complex of vesicles and folded membranes involved in secretion and intracellular transport.
(endomembrane) Organelle containing degradative enzymes enclosed in a membrane.
(endomembrane) A vacuole with a digestive function in the protoplasm of protozoan.
(endomembrane) A vacuole in some protozoans that expels excess liquid on contraction.
(endomembrane) Organelle found in plant cells, surrounded by a membrane, that holds materials and waste.
cell membrane/plasma membrane
(endomembrane) The semipermeable membrane surrounding the cytoplasm of a cell.
Structure that helps cells maintain their shape and internal organization.
(cytoskeleton) A microscopic tubular structure acting as conveyer belts inside the cell.
(cytoskeleton) The thinnest filaments of the cytoskeleton, that when linked together can provide stiffness and shape to a membrane.
(cytoskeleton) Provides support for the plasma membrane where it comes into contact with the other cells.
(specialized microtubules) (cytoskeleton) Form the network of microtubules that participate in making the cytoskeleton.
(specialized microtubules) (cytoskeleton) Help with cell division of animal cells. Help form spindle fibers.
(specialized microtubules) (cytoskeleton) Move a cell, or form a barricade in the lungs of humans to stop harmful particles from entering.
(specialized microtubules) (cytoskeleton) Function as locomotion or sensory organelle.
Responsible for the production of proteins.
An organelle that performs cellular respiration. The "power house" of the cell.
Organelles that work to convert light energy into sugars.
Organelle that detoxifies alcohol, breaks down fatty acids, is bound by a single membrane, found in kidney and liver cells
A rigid layer of polysaccharides outside the plasma membrane of plant, fungi, and bacteria cells.
double phospholipid membrane with the polar hydrophilic heads forming the outer faces and the nonpolar hydrophobic tails pointing toward the inside of the membrane
provides mechanical support and helps bind adjacent cells together
anchor cells to one another or to provide a passageway for cellular exchange
tightly stitched seam between animal cells that prevents the passage of materials between the cells
narrow channels that are responsible for material exchange
a type of intercellar junction in animal cells that functions as a rivet, fastening cells together, such as in muscle
Cell wall of cellulose
Desmosomes, tight, and gap junctions
Extracellular matrix (ECM)
