Across
- 3. The stage when the cell prepares itself for the process of cell division, and DNA replication takes place. The cell also makes more of its sub-cellular structures.
- 5. The stage of mitosis in which the separated chromosomes move away from each other.
- 8. Cell that joins with other xylem cells to form long, thick-walled vessels after they die. The vessels carry water and dissolved mineral salts through the plant.
- 11. A cell with two sets of chromosomes.
- 14. A th division of a group. For example, 10 per cent of the data items are below the 10th percentile and 50 per cent are below the 50th percentile.
- 15. An organism that is made of many cells.
- 18. Filament formed in a cell during mitosis, which helps to separate chromosomes.
- 19. When the cytoplasm of the cell is separated as the cell membrane is pinched to divide the cell into two daughter cells.
- 20. cell New cell produced by cell division.
- 21. Lump formed of cancer cells.
- 22. Offspring from asexual reproduction. All the cells in a clone are genetically identical to each other and to the parent’s cells.
- 23. When something gets longer (such as a cell in a plant root or shoot before it differentiates into a specialised cell).
- 24. Producing new organisms from one parent only. These organisms are genetically identical to the parent.
Down
- 1. A permanent increase in the number or size of cells in an organism.
- 2. The stage of mitosis in which the chromosomes arrive at opposite ends of the cell and the nucleus membrane reforms.
- 4. Cell that divides uncontrollably.
- 6. The stage of mitosis in which the nucleus starts to break down and spindle fibres appear.
- 7. A small area of undifferentiated cells in a plant, such as near the shoot tips and root tips, where cells are dividing rapidly by mitosis.
- 9. The process of cells dividing to produce two daughter cells that are genetically identical to the parent.
- 10. A cell with one set of chromosomes.
- 11. When a group of similar things, such as cells, become different in form from each other.
- 12. Disease caused by the uncontrolled division of stem cells in a part of the body.
- 13. The stage of mitosis when the chromosomes line up across the middle of the cell.
- 16. Cell found on the surface of plant roots that has a large surface area to absorb water and dissolved mineral salts quickly from the soil.
- 17. A sequence of growth and division that happens in cells. It includes interphase and mitosis, and leads to the production of two daughter cells that are identical to the parent cell.
- 20. The copying of the DNA within a cell.
