cells

5. / A small round structure in a cell that breaks down nutrient molecules and old cell parts
6. membrane / A thin structure that surrounds and protects the nucleus
7. / Characterized by having cells with a membrane-bound nucleus and membrane-bound organelles
11. / The viscous, gel-like substance inside the cell where most of the cell's activities take place
13. division / The process of a cell dividing into two daughter cells that have the same genetic material.
14. / An organism made up of two or more cells
17. reticulum / A small network of tubes that substances move along within a cell

1. / Small round structures within a cell that make proteins. Though often called organelles, they are not organelles
2. / A central organelle of a eukaryotic cell that is like the command center and that contains the DNA
3. / A membrane-bound organelle within plant and animal cells that function as cell storage, waste disposal, protection, growth, and/or structural support
4. apparatus / Organelles that package and send materials to other places
8. / The structure in a plant cell that contains chlorophyll
9. / An organism made of only one cell
10. / A green pigment in plants and algae that absorbs light energy that is used to carry out photosynthesis
12. / These organelles use oxygen to transform the energy in food to a form the cell can use to carry out various activities, like a "powerhouse"
15. / A unicellular organism that does not have a membrane-bound nucleus or membrane-bound organelles, including archaea and bacteria
16. / Small structures in the cytoplasm of cells that have a specific structure and function and do specialized jobs
