mitochondria
site of ATP production; often called the powerhouse of the cell. Mitochondria and chloroplasts are the organelles that convert energy to forms that cells can use for work.
Mitochondria are the sites of cellular respiration, generating ATP from the catabolism of sugars, fats, and other fuels in the presence of oxygen
centrioles
during mitosis, forms the spindle and asters; forms bases of cilia & flagella
site of lipid and steroid synthesis; lipid metabolism; drug detoxification
smooth ER
makes (processes) all proteins secreted from the cell; it also makes (processes) proteins and phospholipids destined for the plasma membrane
rough ER
intermediate filaments
stable cytoskeletal elements which resist mechanical forces
Golgi apparatus
modifies and then packages substances into vesicles for transport to their final destination (either elsewhere in the cell or to the plasmamembrane.The Golgi apparatus finishes, sorts, and ships cell products
Many transport vesicles from the ER travel to the Golgi apparatus for modification of their contents.
The Golgi is a center of manufacturing, warehousing, sorting, and shipping.

flagella
propel cells. The cilium or flagellum is anchored in the cell by a basal body, whose structure is identical to a centriole.
Proteins that are secreted by the cell via the endoplasmic reticulum.
secretory protein
A tiny membranous sac in a cell's cytoplasm carrying molecules produced by the cell.
transport vesicle
A type of intercellular junction in animal cells that prevents the leakage of material between cells.
tight junction
A long surface projection that propels a prokaryotic cell through its liquid environment; totally different from the flagellum of a eukaryotic cell
prokaryotic flagellum
A surface appendage in certain bacteria that functions in adherence and the transfer of DNA during conjugation.
pilus (plural, pili)
A fairly rigid, chemically complex structure that exists outside the plasma membrane of most prokaryotes.
prokaryotic cell wall
The region in a prokaryotic cell consisting of a concentrated mass of DNA.
Nucleoid region
The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles.
endomembrane system
The cell's cytoskeleton are.
1. To provide support and stucture.
2. Cell movement (celia, flagella)
3. chromosome movement in cell division.
4. transmit impulses
Name the 3 organelles that make up the cytomembrane system (start at teh nucleus)
1. endoplasmic reticulum (ER)
2. golgi body
3. nuclear membrane
What 3 features ae found in plants that are completely lacking in animal?
Cell walls
central vacuole
plastids
What are the 2 generalizations of the cell theory of 1850?
1.All organism are composed of cells.
2.Smallest unit of life.
3.All cells arise from pre-existing cells.
What two structures aid in cell movement?
Cytoskeleton and microtubules help aid in cell movement.
