- 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
