Phili
attachment strucures on the surface of some prokaryotes
Nucleoid
region where the cell's DNA is located) not enclosed by a membrane
ribosomes
organelles that synthesize proteins
cell wall
rigid structure outside teh plasma membrane
plasma membrane
membrane enclosing the cytoplasm
capsule
jelly-lke outer coating of many prokaryotes
flagella
locomotion organelles of some bacteria
nuclear envelope
double membrane enclosing the nucleus,
nucleolus
nonmembranous organelle involved in production of ribosomes; a nucleus has one or more nucleoli
chromatin
material consisting of DNA and proteins; visible as individuals chromosomes in a dividing cell.
nucleus
inludes nuclear envelope, nucleolus, and chromatin
plasma membrane
membrane enclosing the cell
ribosomes
nonmembranous organelles (small brown dots) that make proteins free in cytoplasm or boun dto rough ER or nuclear envelope.
golgi apparaturs
organelle active in synthesis, modification, sorting and secretion of cell products.
lysosome
digestive organelle where macromolecules are hydrolyzed
mitochondrion
organelle where cellular respiration occurs and most ATP is generated
peroxisome
organelle with various specialized metabolic function; produces hydrogen peroxide
microvilli
projecctions that increase the cell's surface area
cytoskeleton
reinforces cell's shape, function in cell movement; components are made of protein
centrosome
region where the cell's microtubles where initiated in an animal cell, contains a pair of centrioles
flagellum
locomotion organelle present in some animal cells; composed of membrane enclosed microtubies
endoplasmic reticulum
rough ER and Smoooth ER
central vacuole
prominent organelle in older plant cells, functin include storage, breakdown of waste product, hydrolysis of macromolecules; enlargement of vacuole is a major mechanism of plant growth
tonoplast
membrane enclosing the central vacuole
cell wall
outer layer that maintains cells' shape
