  1. Cell Types

  2. Try these • Balance book on head • Hop on one leg • Specialisation increases the ability of an organism to carry out complex tasks • Some tasks can be completed better by some cells than others.

  3. Cell specialisation Generalised cells can divide and specialise (egmeristem cells in plants & stem cells in animals) Specialised cells have specific structure and function, eg epithelial cells, muscle cells Active cells have more mitochondria, eg animal cells have more than plant cells

  4. Connective tissue Adipose tissue Fat-storage cells Red blood cells No organelles (“dead”)

  5. Epithelia – linings & covers Goblet cells – secrete mucous

  6. Muscles cells Need lots of energy so have lots of mitochondria

  7. Liver cells Liver cell with lots of mitochondria

  8. MENU Quick Quiz Key Words

  9. Key words Back to menu • Animal cell • Plant cell • Active cells • Mitochondria • Epithelium • Muscle • Nervous tissue • Connective tissue

  10. Quick quiz Back to menu True / False? • Animal cells usually have more mitochondria than plant • Centrioles are only found in plant cells • Plant cells have a large vacuole • Chloroplasts are found in all photosynthesising plant cells • Plant cell walls prevent cells bursting • Animal cells lose water when placed in pure water • Plant cells undergo plasmolysis when placed in pure water • Active cells (eg muscle & liver) contain many mitochondria • Red blood cells are animal cells so they have a nucleus • Goblet cells produce mucous Answers
