Across
  1. 6. when a pair of chromosomes have the same genes but one is from each parent
  2. 7. caused by crossing over and independent assortment
  3. 8. where a cell temporarily leaves the cell cycle, it is either specialised or senescent
  4. 10. a specialised cell with no nucleus and a biconcave shape
  5. 12. when a cell has a specific structure and function and can no longer divide
  6. 15. a collection of different organs working together for a specific function
  7. 17. the splitting of the whole cell to form two new daughter cells
  8. 18. where chromosomes are visible and condensed, the nucleolus disappears and the nuclear envelope has disintegrated
  9. 19. The sister chromatids separate at the centromere
  10. 20. consists of G1, S and G2
Down
  1. 1. stem cells are stem cells that can differentiate into any cell type found in an embryo
  2. 2. when chromosomes decondense and nuclear envelope begins to reform, nucleoli form within each nucleus again.
  3. 3. the type of daughter cells that form as a result of meiosis
  4. 4. a collection of one or more tissues working together for a specific function
  5. 5. Cytokinesis in animal cells, involving the constriction of the cytoplasm
  6. 9. where the cell increases in size and mass
  7. 11. signals the movement onto the next phase in the cell cycle
  8. 13. the type of daughter cells formed as a result of mitosis
  9. 14. chromosomes line up on the metaphase plate and spindle fibres attach to the centromeres
  10. 16. collection of specialised cells working together for a specific function
