Cell Specialisation
Across
- 5. The passive movement of particles from an area of high concentration to an area of lower concentration.
- 8. A layer of cells in the leaf adapted for photosynthesis, containing many chloroplasts.
- 9. The process through which unspecialised cells become specialised in structure and function.
- 11. The organelle in plant cells where photosynthesis takes place.
- 15. A type of white blood cell that is part of the immune system, involved in targeting specific pathogens.
- 19. Cells that surround the stomata and control their opening and closing.
- 21. The process by which cells develop specific structures and functions to perform particular tasks.
- 22. A protective glycoprotein layer surrounding the egg cell.
- 24. Reproductive cells (sperm and egg) that combine during fertilisation to form a zygote.
- 25. The pressure exerted by water inside a plant cell that helps maintain the plant's structure.
- 26. The shape of red blood cells that increases their surface area for efficient oxygen exchange.
- 28. An extension of a root cell that increases surface area for water and mineral absorption.
- 29. The process by which cells, especially white blood cells, engulf and digest foreign particles or pathogens.
Down
- 1. The process by which plants convert light energy, carbon dioxide, and water into glucose and oxygen.
- 2. A nucleus divided into several lobes, typical of certain white blood cells like neutrophils.
- 3. The protein in red blood cells that binds to oxygen and transports it to the tissues.
- 4. The liquid found in the vacuole of a plant cell, containing water, sugars, salts, and other dissolved substances.
- 6. A specialised structure within a cell that performs a specific function (e.g., mitochondria, nucleus).
- 7. A cell containing half the normal number of chromosomes, typical of gametes.
- 10. A cap-like structure on the head of a sperm cell that contains enzymes to help it penetrate the egg.
- 12. The measure of how much exposed area a cell or structure has, important for processes like absorption.
- 13. A whip-like tail found on sperm cells, enabling movement.
- 14. Organelles containing digestive enzymes that break down waste materials and cellular debris.
- 16. Cells that have not yet developed a specific role or function in the body.
- 17. Small openings on the surface of a leaf that allow gas exchange (e.g., oxygen, carbon dioxide).
- 18. A microorganism, such as a virus or bacterium, that can cause disease.
- 20. A molecule that stores and provides energy for many cellular processes.
- 23. A layer of cells that surrounds the egg and provides it with nutrients.
- 27. Red blood cells responsible for carrying oxygen throughout the body.
