Nucleus
Larger membrane-bound, spherical prooplasmic structure within living cell; brains of cell
Organelles
differentiated structure within a cell such as mitochondrion, vacuolee or chloroplast; have specific function
Nucleolus
small, round grandular body composed of proteins and RNA in the nucleus, involved in RNA synthesis and ribosome formation
Ribosome
a minute round praticle composed of RNA and protein that is ofund in the cytoplasm of living cells and serves as the assembly site of polypeptides encoded by messenger RNA
Smooth Endoplasmic Reticulum
internal membrane structure of eukaryotic cell; lacks ribosome binding function of rough ER
Rough Endoplasmic Reticulum
membrane organelle of eukaryotes that forms sheets and tubules
Golgi Apparatus
network of stacked membranous vesicles present in most cells that functions in the formation of secretion within the cell
Lysosomes
organelle in the cyoplasm of cells containing various hydrolytic enzymes that function in intracellular digestion
Vacuoles
small cavity in cytoplasm of cell, bound by a single membrane containing water, food, or metabolic waste
Mitochondria
organelle in cytoplasm in eukaryotic cells, contains genetic material and many enzymes important for cell metabolism, coverts food to energy
Chloroplasts
chlorophyll-containing plastid found in Plants
cytoskeleton
internal framework of a cell composed largely of actin filaments and microtubules
Microvilli
minute harilike structure projecting from the surface of certain types of epithelial cells; small intestine
Flagella
long threadlike appendage very whip like used for locomotion
Cilium
microscopic hairlike process extending from surface of a cell; rhythmical motion, moves cell or it's surroundings
Prokaryotic Cell
organism of the kingdom Monera, mainly bacteria, charracterized by the absence of membrane bound nucleus or organelles, and DNA not organized into chromosomes
Eukaryotic Cell
cells contain a distinct membrane bound nucleus
Homeostasis
the ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes
Meiosis
process of cell division; chromosomes go from diploid to haploid; produce gamates in animals and spores in plants
