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
