Across
  1. 1. The stage in the cell cycle when the contents of the nucleus separate into two identical copes
  2. 4. The third phase of mitosis, when the chromosomes separate and move to opposite ends of the cells
  3. 5. Specialized cells working together to perform a function; the four major types of human tissue are muscle tissue, connective tissue, nervous system, and epithelial tissue
  4. 8. The stage in the cell cycle when cytoplasm and organelles divide into two identical, separate cells
  5. 9. exchange The process of taking in oxygen and releasing carbon dioxide
  6. 10. The second phase of mitosis, when the chromosomes align in the centre of the cell
  7. 11. The fourth phase of mitosis, when the membrane surrounding the nucleus re-forms, creating two new nuclei
  8. 12. The process by which nutrients diffuse or are moved from the digestive system to the blood
  9. 14. The movement of molecules or other particles from an area od high concentration to an area of low concentration until they are evenly distributed
  10. 17. The ability to grow new cells to replace damaged or lost body components
  11. 19. Air sacs in the lungs where gas exchange occurs
  12. 20. blood cells Blood cells that carry oxygen and carbon dioxide in the blood
Down
  1. 2. The stage in the cell when a cell grows and carries out it usual functions, as well as making a copy of its DNA and organelles to prepare for cell division
  2. 3. Tiny blood vessels that play an important role in gas exchange
  3. 6. The first phase of mitosis, when the nucleus and nuclear membrane disappear and chromosomes form
  4. 7. imaging technology Technologies that are used to make images of cells, tissues, and organs
  5. 8. The number of molecules of a substance in a given volume
  6. 13. A structure within a cell that carries out specific functions to support the life of the cell; functions include bring in nutrient, removing wastes, generating and releasing energy for the cell to use, making substances that the cell needs, and reproducing
  7. 15. Different tissues working together to perform a specific task; connective, nervous, and epithelial tissues make up the brain
  8. 16. cycle The continuous series of events in the life of a cell in which it is born, grows, reproduces, and dies
  9. 18. The movement of water molecules across a membrane in response to concentration differences
