functions of the parts of a cell

cell wall

-extra barrier made of cellulose
-outside of plant cell
-support

vacuole-

-large and central storage of water

chloroplast

-green cause of chlorophyll
-energy from sun is turned into sugar

microfilaments and microtubules

-form the cytoskeleton (framework) of the animal cell

microfilaments

rod like and provide movement

microtubules

long slender tubes of protiens that provide framework for cell

cilia

short hair like for movement
-made of microtubles

flagella

-long whip like for movement
-made of microtubles
-ony human cell with this is the sperm cell

cell membrane

-semipermeable
-phospholipid bylayar embeded w/ proteins
-protiens act as channels
-contain ID tags
-fluid mosaic model

nucleus

-big large round structure
-surrounded by nuclear envelope
-stains purple usually
-contains nucleus and chromosones
-control center for cell

nucleolus

-small inside nucleus
-makes ribsomes
-has nucleolus plasma (jelly like material)

chromatin

-dna of cell
-function involved with heditary
-blueprint of cell
-chromoson: shortened/condensed/replicated

cytoplasm

-everything in cell membrane beside nucleus
-cytosol: jelly surronding organelle
-organelles are suspended in glytosol
-chemical reaction take place

mitochondria

-bean shaped
-food is converted to energy
-crista: where ATP takes place

ribsome

-smallest, most important
-spherical organelles where protein is synthesized
-located throughout cell rough er
-made of ribosomal rna

rough endoplasmic reticulum

-elongated canal like membrane
-connects nuclear envelope or outside of nucleus
-transports proteins

smooth endoplasmic reticulum

-branching network of tubules
-no ribosomes
-usually connected to rer
-transports lipids
--detoxification of drugs

golgi apparatus

-stacks like pancakes
-secretes and packages

lysosome

-cleans cellular debris
-pinch of golgi
-attach to bacteria cells
-dygestive enzymes
