|
Flagellum
|
Locomotion organelle present in some animal cells; composed of a cluster of microtubules within an extension of the plasma membrane
|
|
Centrosome
|
Region where the cell's microtubules are initiated; contains a pair of centrioles (function unknown)
|
|
Cytoskeleton
|
Reinforces cell's shape, functions in cell movement; components are made of protein.
includes microfilaments, intermediate filaments, microtubules
|
|
Microvilli
|
Projections that increase the cell's surface area
|
|
Peroxisome
|
Organelle with various specialized metabolic functions; produces hydrogen peroxide as a by-product, then converts it to water
|
|
Mitochondrion
|
Organelle where cellular repsiration occurs and most ATP is generated
|
|
Lysosome
|
Digestive organelle where macromolecules are hydrolyzed
|
|
Golgi apparatus
|
Organelle active in synthesis, modification, sorting, and secretion of cell products
|
|
Ribosomes
|
Complexes (small brown dots) that make proteins; free in cytosol or bound to rough ER or nuclear envelope
|
|
Plasma membrane
|
Membrane enclosing the cell
|
|
Endoplasmic reticulum (ER)
|
Active in membrane synthesis and other synthetic and metabolic processes; has rough (ribosome-studded) and smooth regions
|
|
Nuclear envelope
|
Double membrane enclosing the nucleus; perforated by pores; continuous with the ER
|
|
Nucleolus
|
Nonmembranous organelle involved in production of ribosomes; a nucleus has one or more nucleoli
|
|
Chromatin
|
Material consisting of DNA and proteins; visible as individual chromosomes in a dividing cell
|
|
Central vacuole
|
(plant cell) functions include storage, breakdown of waste products, hydrolysis of macromolecules; enlargement is a major mechanism of plant growth
