Term | Definition |
Organelle | a tiny cell structure that carries out a specific function within a cell |
nucleus | the control center of the cell that directs the cell's activities; it contains the chemical instructions that direct all the cell's activities (DNA) |
cell membrane | thin, flexible barrier around a cell, it regulates what enters and leaves the cell |
cytoplasm | The area inside a cell between the nucleus and the cell membrane, where organelles can be found |
chloroplasts | organelles that capture energy from the sunlight and use it to produce food for the cell |
ribosome | the organelle in which amino acids are hooked together to make proteins |
endoplasmic reticulum | the organelle that makes lipids, breaks down drugs and other substances, and packages proteins for the Golgi complex |
mitochondria | the organelle that breaks down food molecules to make energy available (ATP) |
Golgi complex | the organelle that processes and transports proteins and other materials out of the cell |
vacuole | the organelle that stores water and other materials |
lysosome | the organelle that digests food particles, wastes, cell parts, and foreign invaders |
Cell Wall | Ridged outer layer of plant cell |
Cell Theory | 1.All living things are composed of cells.
2. Cells are the basic units of structure and function in living things.
3. New cells are produced from existing cells |
Eukaryote | Cells that contain nuclei
Complex
Example: animal cells, plant cells |
Prokaryotes | Cells that do not contain nuclei
Simple
Example: bacteria |
