Transcript

  • 1. Chapter 1: Lesson 1: What are the structures of plant and animals cells? Grade 5
  • 2. Study the pictures shown, then circle living things with a RED marker and non-living things with a BLUE marker.
  • 3. Any living thing. Organism
  • 4. What is this building made of?
  • 5. Cement Iron Bricks (Smallest building unit) Wood
  • 6. All organisms are made of building blocks (units) called Cells
  • 7. What do cells do? Cells help us: 1) 2) 3) 4) 5) 6) 7) Grow Breathe Move Reproduce (make more of its kind) Excrete (remove wastes from their bodies) Respond to stimulus (feel the weather changes, etc) Feed
  • 8. Cells Smallest unit of living things that can carry out the basic processes of life.
  • 9. Cells Unicellular Multicellular (1 celled organism) (Multi celled organisms)
  • 10. Animal Cells Cell membrane Cytoplasm Nucleus Vacuole Mitochondrion
  • 11. Animal Cell organelle functions 1) Cell membrane - Give the cell its shape. - Controls what materials enter the cell and what materials leave the cell.
  • 12. 2) Cytoplasm - Gel like liquid mostly made of water. - It fills the area between the cell membrane and nucleus (organelles float in it). - Some of the life processes take place in it.
  • 13. 3) Nucleus - Have a membrane with pores to allow certain substance in and out of the nucleus. - Controls all the cell functions (the brain of the cell).
  • 14. 4) Vacuole - A membrane covered structure used for storage (stores food, water and wastes). - Some animal cells have many small vacuoles and some do not have vacuoles.
  • 15. 5) Mitochondria - Oval, membrane covered organelle that breaks down food to give energy to the cell (power plant). - Animal cells that need more energy (ex. muscle cells) have many mitochondria.
  • 16. Plant Cell organelle functions 1) Cell Wall - Stiff structure outside the cell membrane. - It provides the cell with strength and extra support.
  • 17. 2) Cell membrane - Controls what materials enter the cell and what materials leave the cell.
  • 18. 3) Cytoplasm - Gel like liquid mostly made of water. - It fills the area between the cell membrane and nucleus (organelles float in it).
  • 19. 4) Nucleus - Have a membrane with pores to allow certain substance in and out of the nucleus. - Controls all the cell functions (the brain of the cell).
  • 20. 5) Vacuole - 1 large central vacuole used for storing excess water and providing extra support to the plant.
  • 21. 6) Mitochondria - Oval, membrane covered organelle that breaks down food to give energy to the cell (power plant).
  • 22. 7) Chloroplast - A green structure where energy from the sunlight is used to make the plants food. (Contains chlorophyll)
