nucleus control center; contains DNA
nuclear membranea two-layered envelope around the nucleus
nuclear pores large openings in the nuclear membrane
mitochondria powerhouse of the cell; produces ATP aerobically
cytoplasm gel-like substance that supports cell parts
lysosome suicide sac of the cell
endo. retic. contains ribosomes to make proteins
vacuole storage area in cell
centriole involved in cell division of a cell
nucleolus produces RNA; a part of the nucleus
cell membrane also called plasma membrane; determines what gets into a cell
Golgi complex chemically processes and secretes materials
cell basic unit of life
cell theory all life made of cells/cells unit of life/cells come from cells
cell wall strong supporting structure outside membrane; found in plants
eukaryote organism with cell(s) with a nucleus and cell parts
prokaryote organism with cell(s) with no nucleus and few cell parts
chromosome structure made of DNA & some proteins seene when cell divides
chromatin structure made of proteins and DNA in an active form
organelle a cell part
plastid a plant cell part like the chloroplast
chloroplast plant cell part that does photosynthesis; contains chlorophyll
prokaryote a cell that has nucleus - such as a bacterium
eukaryote a cell with a nucleus
ribosome structure where proteins are manufactured
vacuole may store water proteins lipids salts
cytoskeleton an internal cell framework made of tubules and filaments
microtubules pipe-like structures that make up cilia and flagella
microfilamnets thread-like structures that help things to move in a cell
diffusion movement of a substance from high to low concentration
isotonic concentration of solutes is the same inside and outside cell
hypotonic concentration of solutes is lower outside the cell than inside
hypertonic concentration of solutes is higher outside the cell than inside
plasmolysis shrinking of a cell due to loss of water
permeability ability to allow substances through a membrane
osmosis diffusion of water through a membrane
carrier molecul.molecules in the cell membrane that help substances to pass in/out
active transportuse of cell energy to move substances from low to high conc.
passive transprtmoving substances from high to low concentration - no cell energy used
phagocytosis cell taking in large food particles by active transport
pinocytosis cell taking in liquid material by active transport
specialization some cells do one job while other cells do other jobs
tissue a group of similar cells that do a particular function
organ several tissues working together to do a particular function
organ system several organs working together to do a particular function
facilitated a type of diffusion which is assisted by carrier molecules
