Across
- 5. cloning Producing an embryo that has the same genes as a patient
- 7. cell A type of cell found in plants and animals that contains a nucleus
- 8. The spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration
- 10. stem cell A type of stem cell that can form many types of cells

- 18. wall An outer layer made of cellulose that strengthens plant cells
- 22. differentiation The process where a cell becomes specialised to its function
- 23. cell cycle A series of stages preparing the cell for division
- 26. gradient The difference in concentration between two areas

- 18. membrane A partially permeable barrier that surrounds the cell
- 19. The diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane
- 20. transport The movement of substances from a more dilute solution to a more concentrated solution (against a concentration gradient) with the use of energy from respiration
- 21. area to volume ratio (SA:V) The size of the object compared with the amount of area where it contacts its environment

- 25. Loops of DNA found in the cytoplasm of prokaryotic cells
- 28. A type of cell division which produces two genetically identical daughter cells from one parent cell
