|
plasma membrane
|
outer boundary composed of phospholipids, cholesterol and protein that encloses cytoplasm; Guards; communicates; identifies
|
|
|
cytoplasm
|
lies between plasma membrane and nucleus; internal living material of cells; contains numerous structures of cell as well as the fluid as the internal environment
|
|
|
nucleus
|
double membraned spherical envelope containing DNA that dictates protein synthesis; ATP, metabolism, growth, and heredity
|
|
|
interstitial fluid
|
fluid located in microscopic spaces between cells
|
|
|
tissue fluid
|
a dilute salt water solution that bathes every cellular body
|
|
|
organelle
|
cell organ
|
|
|
phospholipid
|
phosphate containing fat molecule; doubled up forms the plasma membrane
|
|
|
ribosomes
|
"protein facory"; synthesises protein inside the cytoplasm of the cell
|
|
|
endosplasmic reticulum
|
absorbd proteins from Ribosomes to carry to areas that processes them chemically; manufactures fats, proteins and carbs to make cellular mebrane; rough- recieves and transports proteins, smooth- synthesises lipids and carbs
|
|
|
golgi apparatus
|
tiny flattened sacs stacked on top of one another close to nucleus; fuse with protein containing vesicles from smooth ER, chemically processes it, packages in other vesicles, breaks off and sends out to and through plasma membrane; "Chemical processings and packaging center"
|
|
|
mitochondria
|
2 membranous sacs; "power plants"; contain enzymes to use oxygen for breaking down glucose and other nutrients
|
|
|
lysosomes
|
contain enzymes to digest food compounds; "Digestive bags"; Protect cells against destruction
|
|
|
centrioles
|
paired rod shaped structures that lie at right angles to eachother; plays important role in cellular division
|
|
|
cilia
|
extremely fine hairlike extensions on exposed/ free surface on some cells; move together in wavelike motion; ex. propels mucus upward over cells that line respiratory tract
|
|
|
flagella
|
single long projection extending from cell surface used for movement; only one in body is sperm cells "tail"
|
