Cells

3. Organelles found in plant cells and algae that perform photosynthesis, converting sunlight into energy.
5. (ER) A network of membranes that transports materials throughout the cell. It comes in two types
8. Small, specialized structures within a cell that perform specific functions.
11. A dense structure within the nucleus that produces ribosomes.
12. Often called the "powerhouse" of the cell, these organelles generate energy (ATP) through cellular respiration.
14. A thin, semipermeable layer that encloses the cytoplasm of a cell, controlling the passage of substances in and out.
15. A membrane-bound sac used for temporary storage of water, food, or waste. Plant cells have a large central vacuole.
17. A small, membrane-bound sac that transports materials within a cell.
18. Hair-like projections that extend from the cell surface and are used for movement or moving fluids over the cell.
19. cell A simple cell that lacks a nucleus and other membrane-bound organelles.

1. A network of protein filaments that gives the cell its shape and aids in movement.
2. Vesicles contain enzymes that break down waste materials, cellular debris, and foreign particles.
4. A rigid outer layer found in plant cells, fungi, and some bacteria that provides structural support and protection.
6. Tiny structures responsible for protein synthesis.
7. The jelly-like substance that fills the cell, containing all the organelles.
9. Long, whip-like appendages used for cell locomotion.
10. Structures found in animal cells that help organize cell division.
11. The control center of the cell, containing the cell's genetic material (DNA).
13. A stack of flattened sacs that modifies, sorts, and packages proteins and lipids for transport.
16. cell A cell that contains a nucleus and other membrane-bound organelles.
