Across
  1. 2. Reticulum / Organelle in eukaryotic cells with a series of highly folded membranes. Site of cellular chemical reactions. Helps transport proteins and other substances.
  2. 5. / Cellular framework found within the cytoplasm. Composed of microtubules and microfilaments.
  3. 6. / Membrane bound organelles containing digestive enzymes. They digest excess or worn out organelles, food particles, viruses, or bacteria.
  4. 8. / Light absorbing pigment in plants and some protists that is required for photosynthesis. Absorbs most wavelengths of light except green.
  5. 12. / Chlorophyll containing cell organelles found in the cells of green plants and some protists. They capture light energy from the sun and convert it to chemical energy in food molecules. Site of photosynthesis.
  6. 14. / Thin solid protein fibers that provide structural support. Component of the cytoskeleton.
  7. 15. Membrane / Controls what enters and leaves the cell. Separates the external environment from the cell’s interior.
  8. 16. / Clear gelatinous fluid in eukaryotic cells that suspends the cell's organelles and is the site of numerous chemical reactions. Fills the space between the nucleus and the plasma membrane.
  9. 17. / Controls cell division and other cell functions and contains genetic information in the eukaryotic cell.
Down
  1. 1. Wall / Firm, fairly rigid structure located outside the plasma membrane of plants, fungi, most bacteria, and some protists.
  2. 3. / Membrane bound organelle that transforms energy stored in food into ATP. Has a highly folded inner membrane. Powerhouse of the cell.
  3. 4. / Organism’s regulation of its internal environment to maintain conditions suitable for survival. Process of maintaining equilibrium in an organisms internal environment.
  4. 7. / Basic unit of structure and function in organisms.
  5. 9. / Membrane bound fluid filled space used for temporary storage. Very large in plant cells.
  6. 10. Apparatus / System of flattened membrane tubes. Modifies proteins, packages proteins and sends them to the appropriate destination.
  7. 11. / Controls what enters and leaves the cell. Separates the external environment from the cell’s interior.
  8. 13. / Non-membrane –bound organelles that assemble proteins. Site of protein synthesis.
