strong and stiff

made out of cellulose

found in plant cells

allows certian particals to go thru

animal cells: no  cell wall, membrane has cholestrol

has pores

controls movement of materials

nade out of lipids,protiens and cholestrol

Control center

surronded by membrane

membrane has pores

"brain" of the cell

thick, rodlike objects

direct all activites in cell

pass traits on to other cells

carriers of the blueprints of life

store genetic information

DNA stays inside nucleus

RNA leaves the nucleus thru pores in membrane

site of ribosome production

thick, jellylike substance

always moving

many organelles located inside it

transporting system

carrys protiens from one part of the cell to another

is "rough" because it has ribosomes attached to it

Ribosomes

protien factories

produced in nucleus

many of them attached to ER

made up of RNA

some float freely in cytoplasm

Powerhouses

supply most energy

sugars broken down into water/carbon dioxide gas

stores energy

mit. have small amount of DNA

once tiny living orgonisms

storage tanks

food and others material stored  inside vacuole

can store waste products

main water storage area

when vacuole full it swells and plumps

clean up crew

contain enzymes, break down large food molecules

digests old cell parts

energy producers for plant cell

large and green

they are green because they contain chlorophyll

chlorophyll captures energy from the sun

chlorophyll filled with it

funtions in photosynthesis

composed of stacks of thylocoids that contain chlorophyll

cite of photosynthesis

Chloroplasts have double membrane and inside the membrane are the thylacoids.

thyacoids appear in grana

transporting system

carrys protiens from one part of the cell to another.

is "smooth" because that is the way it appears and has no ribosomes attached to it

packages macromolecules

membrane bound structure with a single membrane

helps mantain cell shape

made from microtubules, microfilements and intermidiate fibers
