Chapter 4- parts of the cell

Rough Endoplasmic Reticulum

synthesis of proteins (translation)

Ribosomes

free floating

synthesize proteins that stay in the cell

Smooth Endoplasmic Reticulum

does not have ribosomes

production/synthesis of lipids

Golgi body - apparatus 

accepts vesicles with molecules inside, and sends them elsewhere

can modify molecules

mitochondrion

single form

allows cell to generate/synthesize most of the adenosine triphosphate (ATP) (energy)

structure and function are correlated to amount

lysosomes

contain hydrolytic enzymes to break down un-needed* material in the cell and get rid of it

*old parts, should not be there

chloroplasts

plant and algal cells

used for photosynthesis to produce glucose

cell wall

provides structure for plant cells

surrounds the membrane

gives extra strength

found in plants

cell membrane

provides protection for the cell itself

gives some structure

difficult to penetrate

nucleus

contains the genetic material of a cell

brain of the cell

q

nucleolus

location in which RNA can be stored

nuclear envelope

membrane around the nuclues

cytoskeleton

mobility

movement from here to there- amoeba

movement within the cell

contains microfilaments, microtubules, intermediate filaments

vacuole

storage area
