|
Ribosomes
|
create proteins and have coded intructions from nucleus. pa
|
|
|
vacuole
|
stores everything a cell needs to survive. examples are water, food, salts, and protein. It is surrounded by a membrane and filled with liquid. pa
|
|
|
nucleus
|
control center for the cell.contains dna that has codes to create proteins and other molecules. pa
|
|
|
cell membrane
|
outside layer for animal cells and just inside cell wall for plant cell. has pours that allow certain things to enter and exit the cell. pa
|
|
|
nuclear membrane
|
outer layer of nucleus. controls what comes in and out of nucleus. pa
|
|
|
cytoplasm
|
jerlly like liquid that fills up space between nucleus and cell membrane. pa
|
|
|
nucleolus
|
organelle in nucleus that creates ribosomes. pa
|
|
|
mitochondrion
|
bean shpaed orgenelle that breaks down sugar and releases energy for the cell. pa
|
|
|
smooth ER
|
breaking down lipid soluable toxins in liver cells and the control of calcium in muscle cells. pa
|
|
|
rough ER
|
looks pebbled because it has ribosomes on it. ribosomes create proteins which go to the rough ER for transport. PA
|
|
|
golgi
|
stack of mebrane bound vessels that transport macromolecules through out the cell. pa
|
|
|
cytoskeleton
|
maintains shape of cell and is network of protein fillaments. involved in movement of cell. pa
|
|
|
chromotin
|
granular material seen in nucleus. contains dna bound for protein. pa
|
|
|
plant cells
|
eukaryotic and have a few similar points to animal cells
|
|
|
cell wall
|
outer layer of cell. rigid nonliving and made of cellulose. oxygen, water, carbon dioxide. p
|
|
|
chloroplast
|
oval shaped structure filled with chlorophyll which is a green pigment. uses suns rays to create food which is called photosynthesis. p
|
|
|
lysossome
|
digestive jobs breaking down large food molecules in to smaller ones and digesting old cell parts. a
|
|
|
centrioles/micro tubles
|
used in cell division which is the process mitosis and miosis.
|
|
|
cell
|
basic unit of life
|
|
|
cell theory
|
-all living things are composed of cells
-cells are basic units of structure and function in living things -new cells are produced from existing cells |
|
|
eukaryote
|
cell that contains nuclei
|
|
|
prokaryote
|
do not contain nuclei
|
|
|
what structure do all cells have
|
have 2 things
all surrounded by cell membrane some point in lives contain molecule that contains biological info(dna) |
|
|
diffusion
|
high consentration to low concentraition. all things
|
|
|
equilibrium
|
when concentraition of cell is equal.
|
|
|
osmosis
|
diffusion of water through permeable membrane. water only.
|
|
|
isotonic
|
same strength
|
|
|
hypertonic
|
above strength
|
|
|
hypotonic
|
below strength
|
