  1. 3. A group of similar cells that work together to perform a specific function.
  2. 7. The process of making something look bigger than it is, often using lenses.
  3. 11. The smallest unit of life. They are often specialised to perform a specific function.
  4. 13. A group of different tissues that work together to perform a specific function.
  5. 14. Organisms made up of only one cell.
  6. 15. The piece of glass used to view objects under a microscope.
  7. 16. A blood cell that carries oxygen around the body.
  8. 17. Sac in the cytoplasm of plant cells containing a watery liquid that keeps the cell firm.
  9. 19. A type of unicellular organism. Many can be found in the human gut.
  10. 20. Liquid, mainly water, making up most of the cell, in which chemical reactions happen.
  11. 22. Flexible outer layer surrounding the cell, which controls which substances can enter and leave the cell (4,8).

  1. 1. A type of blood cells that protects the body from infections.
  2. 2. A type of unicellular organism that has plant and animal-like features.
  3. 4. A tail-like structure that allows cells to move. They can be found in sperm cells and bacteria.
  4. 5. Infectious particles that are the cause of many diseases - including COVID-19! They are not alive!
  5. 6. A piece of scientific equipment used to view very small objects (5,10).
  6. 7. Organelles in the cytoplasm where energy is released from glucose from food by a process called respiration.
  7. 8. Structures found inside cells that have specific functions. "little organs"
  8. 9. Organelles found in cells of green parts of plants (leaves and stems). They contain a green pigment called chlorophyll, where photosynthesis occurs.
  9. 10. The scientific word for a living thing.
  10. 12. Contains the genetic material (DNA) of the organism and controls the cell’s activities.
  11. 18. The movement of particles from an area of high concentration to an area of low concentration.
  12. 20. A tough outer layer of plant cells, which contains cellulose to provide strength and support to the plant (4,4).
  13. 21. A group of different organs that work together to perform a specific function (5,6).
