20 Cards in this Set
- Front
- Back
|
cell membrane
|
-inside cell shells
-tube like, lies around cell -phospholipid bilayer--keeps things in or out |
|
cell wall
|
-outside membrane
-made of cellulose -provides protection from injury and skeletal support |
|
nucleus
|
-center of the cell
-has nuclear pores -communicates with cytosool, makes proteins and other mollecules, command center |
|
nucleolus
|
-on the nucleus
-dense spehere -where ribosomes are produced |
|
nuclear envelope
|
-surrounds nucleus
-nuclear pores [hollow dots], 2 membranes -lets material move in+out of nucleus--such as messeges |
|
chromosomes
|
-spread thru out nucleus
-thread like lumps -contain genetic info passed btwn cell generations |
|
cytoplasm
|
-outside nucleus
-jelly like, made of cytosoll -fills cells. organelles are suspended + held together by fatty membrane. "molecular group" |
|
mitochondria
|
-inside cytoplasm
-double membrane w/folds [cristae] -provides energy - move, divide, contract. and converts chem energy stored in food into compounds for chem use |
|
chloroplast
|
-inside membrane
-2 membranes surround it, large stack of membranes -capture energy from sun + convert to chem energy by photosynthesis |
|
ribosomes
|
-turuout the cytoplasm
-small particles [RNA], bumpy and roughk, protein inside -makes proteins |
|
ER
|
-internal membrane
-membranes - smooth and rough -where lipid components of cell membrane are assembled w/proteins and others exported from cell |
|
golgi apparatus
|
-near cytoplasm
-stack of membranes, wavyish -modify, sort, package proteins for storage/secretion |
|
lysosomes
|
-inside S. E R, cytoplasm
-round, orange, small -filled w/enzymes, needed for intercellular digestion, kill and eat bacteria |
|
vacuoles [leucoplast]
|
-membrane wall, nucleus, cytoplasm
-sac-like, one is large and central -stores life - water, salt, protein, carbs |
|
plastids
|
-inside membrane
-surrounded by double membrane -store specific things - starch, molecules |
|
cytoskeleton
|
-inside membrane
-fillaments of protein; network of many parts -helps support cell, maintain its shape, help move |
|
microtubules
|
-part of cytoskeleton
-tube strips, long -form networks and produce cell framework and help cells move, cell division |
|
cilia
|
-outside cell
-small, hair like -help cell move |
|
flagella
|
-outside celll
-cylindrical lines of fillaments -move liquid past cell's surface |
|
centrioles NOT IN PLANT CELLS
|
-near nucleus
-ring of 9 groups of microtubules -cell division |
