  1. Organelles found only in.... Unicellular Organisms

  2. Oral groove • Paramecium have a permanent organelle which functions in feeding. Oral Groove ----------->

  3. Oral groove • Paramecium have a permanent organelle which functions in feeding. • O.G is a ciliated channel on one side of the cell.

  4. Oral groove • Paramecium have a permanent organelle which functions in feeding. • O.G is a ciliated channel on one side of the cell. • Food is swept into the O.G and cilia move the food inside where a vacuole forms around it so it can be digested.

  5. Oral Groove ----------->

  6. Anal Pores • Where waste is expelled.

  7. Eyespot • Orange granule – usually at the ‘front’ end

  8. Eyespot • Orange granule – usually at the ‘front’ end • Functions in light detection and makes the unicel move towards or away from light.

  9. Contractile Vacuole • Specialised vacuoles which regulate amount of water inside. • When vacuole is full it expels water to the outside of the cell.

  10. Now we are going to play “I have, who has” to see how much you know!
