Cells Crossword Puzzle


Across 1. Thin, solid protein fibers that provide structural support for eukaryotic cells.
3. Chlorophyll-containing cell organelles found in cells of green plants and some protists; capture light energy from the sun, which is conveted to chemical energy in food molecules.
4. Nonmembrane-bound organelles in the nucleus where enzumes and other proteins are assembled.
7. Organelle in eukaryotic cells with a system of flattened tubular membranes; modifies proteins and sends them to their appropriate destinations.
8. Clear, gelatinous fluid in eukarytotic cells that suspends the cell’s organelles and is the site of numberous chemical reactions.
11. Organelle in eukaryotic cell nucleus that produces ribosomes.
14. In animal cells, a pair of small cylindrical structures composed of microtubules that duplicate during interphase of cell division and move to opposite ends of the cell during prophase.
15. Membrane-bound fluid-filled space in the cytoplasm of plant cells used for the temporary storage of materials
16. Organelle in eukaryotic cells with a series of highly folded membranes surrounded in cytoplasm; site of cellular chemical reactions; can either be rudh (with ribosomes) or shmooth (without ribosomes).
17. Cellular framework found within the cytoplasm composed of microtubules and microfilaments.

Down 1. Thin, hollow cylinders made of protein that provide structural support for eukaryotic cells.
2. Organelles that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
5. Eukaryotic membrane-bound organelles that transform energy stored in food molecules into ATP, an organism’s energy storing molecule.
6. In eukaryotic cells, the central membrane-bound organelle that monages cellular functions and contains DNA.
9. Serves as boundary between the cell and its environment; allows materials such as water and nutrients to enter and waste products to leave
10. Cells which lack internal membrane-bound structures.
12. Firm, fairly rigid structure located outside the plasma membrane of plants, fungi, most bacteria, and some protists; provides support and protection.
13. Cells which contain a true nucleus and membrane-bound organelles
