The control center of the cell
Nucleus
A sac of fluid surrounded by a membrane

bubble-like structure that stores water and dissolved minerals

it stores food, enzymes, and other materials needed by a cell
Vacuole
"Powerhouse of the cell,"

releases energy
Mitochondria
An organelle that packages and ships proteins

is composed of closely stacked, flattened sacs

resembles smooth ER in appearance
Golgi complex/Golgi bodies
DNA tangles
Chromatin
short hair-like processes on the plasma membrane of certain cells of an organism that assists in locomotion
Cilia
Traps light and used to make food for plant
chlorophyll
Controls entry of substances into and out of the cell
Plasma membrane or cell membrane
Contains pigments or stores food
Plastid
Membrane surrounding the nucleus
Nuclear membrane
The material that fills the cell and contains the organelles.

Jelly-like material between the nucleus and the cell membrane.
Cytoplasm
makes food for plant cells

a plastid in plants that converts light into usable energy
Chloroplasts
ER that has ribosomes attached to
Rough ER
Cells that contain a highly folded system of membranes


eukaryotic cells
a small structure attached to the ER

the small structure on which proteins are made

Makes proteins or site of protein synthesis
Ribosome
A folded membrane that forms a network of interconnected compartments

where proteins are assembled and transported

the cell's internal transport system

Endoplasmic reticulum
The organelle that recycles waste in the cell

is round and contains digestive enzymes

digests excess or worn-out cell parts, food particles, invading viruses, or bacteria

"clean up crew" of the cell
Lysosomes
