Cells

5. Cells which lack internal membrane-bound structures such as a nucleus.
7. Organelle in eukaryotic cells with a series of highly folded membranes surrounded in cytoplasm; site of cellular chemical reactions; can either be rough (with ribosomes) or smooth (without ribosomes).
9. Chlorophyll-containing cell organelles found in cells of green plants and some protists; capture light energy from the sun, which is converted to chemical energy in food molecules.
11. Organelle in eukaryotic cells with a system of flattened tubular membranes; modifies proteins and sends them to their appropriate destinations.
12. Thin, solid protein fibers that provide structural support for eukaryotic cells.
13. Firm, fairly rigid structure located outside the plasma membrane of plants, fungi, most bacteria, and some protists; provides support and protection.
15. Membrane-bound fluid-filled space in the cytoplasm of plant cells used for the temporary storage of materials

1. Cells which contain a true nucleus and membrane-bound organelles
2. Clear, gelatinous fluid in eukaryotic cells that suspends the cell's organelles and is the site of numerous chemical reactions.
3. Organelles in the nucleus where enzymes and other proteins are assembled.
4. Organelles that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
6. Site in eukaryotic cell nucleus that produces ribosomes.
8. Cellular framework found within the cytoplasm composed of microtubules and microfilaments.
10. Eukaryotic membrane-bound organelles that transform energy stored in food molecules into ATP, an organism's energy storing molecule.
12. Thin, hollow cylinders made of protein that provide structural support for eukaryotic cells.
13. Serves as boundary between the cell and its environment; allows materials such as water and nutrients to enter and waste products to leave
14. In eukaryotic cells, the central membrane-bound organelle that manages cellular functions and contains DNA.
