Across
  1. 3. Contains the cell's genetic material (DNA) and controls cellular activities, including growth and reproduction.
  2. 5. Performs photosynthesis to convert sunlight into energy.
  3. 6. A diverse group of eukaryotic organisms that are mostly unicellular, but some are multicellular or colonial.
  4. 7. Regulates the movement of substances in and out of the cell and provides structural support.
  5. 9. Includes prokaryotic, unicellular organisms without a nucleus or membrane-bound organelles.
  6. 12. The process by which plants use sunlight, carbon dioxide, and water to make glucose (food) and oxygen.
  7. 14. roduces energy in the form of ATP through cellular respiration.
  8. 16. Contains digestive enzymes that break down waste and cellular debris.
  9. 18. Tail like structure that allows movement by rotating
  10. 20. Studded with ribosomes; synthesises and modifies proteins.
  11. 21. Eukaryotic, multicellular organisms that perform photosynthesis.
  12. 22. Eukaryotic, multicellular organisms that consume organic material for energy.
Down
  1. 1. A type of cell division that produces four non-identical cells (gametes), each with half the number of chromosomes as the original cell.
  2. 2. The process of producing energy (ATP) from glucose without using oxygen, often resulting in by-products like lactic acid or ethanol.
  3. 4. Involved in lipid synthesis and detoxification.
  4. 8. Respiration The process of breaking down glucose into energy (ATP) using oxygen.
  5. 10. A type of cell division where one cell divides into two identical cells, each with the same number of chromosomes as the original.
  6. 11. Provides structural support in plant and bacterial cells
  7. 13. Hair like structures that allows movement
  8. 15. Modifies, sorts, and packages proteins and lipids for transport.
  9. 17. Synthesises proteins by translating mRNA.
  10. 19. Eukaryotic, mostly multicellular organisms (some unicellular, like yeast) that absorb nutrients from organic material.
