  3. Complete as we go… The function of the flower in a plant is to allow _________________________. The function of the flower in a plant is to allow REPRODUCTION.

  4. Complete as we go… The process of the male part of a plant fertilizing the female part of a plant, through pollen, is called _____________________. The process of the male part of a plant fertilizing the female part of a plant, through pollen, is called POLLINATION.

  5. Complete as we go… Petals: Attract insects and bees to the flower for pollination

  6. Complete as we go… Sepals: Green, leaf-like structures around the petals to protect the growing flower

  7. Complete as we go… Stamen: the male reproductive structure, holds the ANTHER

  8. Complete as we go… Anther: Produces the pollen than contains the sperm (to fertilize female part)

  9. Complete as we go…. Pistil: The female reproductive structure, in center of flower

  10. Complete as we go… Ovary: At the bottom of the pistil, contains the ovules which hold the eggs

  11. Pollination Steps 1. _________ attract, birds, bees, or other animals that can carry _________, called _____________. 2. ___________ from the ______________ rubs off on the _____________________. 3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”) 4. The _______________ of that flower grows into the fruit or vegetable

  12. Pollination Steps 1. PETALS attract, birds, bees, or other animals that can carry POLLEN, called POLLINATORS. 2. ___________ from the ______________ rubs off on the _____________________. 3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”) 4. The _______________ of that flower grows into the fruit or vegetable

  13. Pollination Steps 1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS. 2. POLLEN from the ANTHER rubs off on the POLLINATOR. 3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”) 4. The _______________ of that flower grows into the fruit or vegetable

  14. Pollination Steps 1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS. 2. POLLEN from theANTHER rubs off on thePOLLINATOR. 3. The pollinator carries that POLLEN to the PISTIL/OVARY of the same or a different flower (“FERTILIZATION”) 4. The _______________ of that flower grows into the fruit or vegetable

  15. Pollination Steps 1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS. 2. POLLEN from theANTHER rubs off on thePOLLINATOR. 3. The pollinator carries thatPOLLEN to thePISTIL/OVARY of the same or a different flower (“FERTILIZATION”) 4. The OVARY of that flower grows into the fruit or vegetable

  16. Complete as we go…. • When fertilization occurs the ovary grows into the fruit or vegetable. • The length of night or dark period controls flowering.

  17. Write in Notebook.. • Plants need these 4 key ingredients:

  18. Video on Photosynthesis • Discovery Education: Oxygen and Green Plants: The Process of Photosynthesis

  19. What does photosynthesis mean? • Photo = light • Synthesis = putting things together • Photosynthesis = putting things together with light

  20. WRITE IN NOTEBOOK • Reactants (what goes in) • What plants use! Water + Carbon Dioxide (H2O) (CO2) + ENERGY from sunlight

  21. WRITE IN NOTEBOOK • Products (what comes out) • What plants produce! Oxygen + Sugar (O2) (C6H12O6)

  22. Photosynthesis • Photosynthesis is how plants use sunlight to make oxygen and sugar. Reactants (what goes in) Products (what comes out) Water + Carbon Dioxide (H2O) (CO2) +ENERGY from sunlight Oxygen + Sugar (O2) (C6H12O6)

  23. BrainPOP! http://www.brainpop.com/science/cellularlifeandgenetics/photosynthesis/preview.weml

  24. My favorite! Mr. Lee!!!!  http://www.youtube.com/watch?v=SYoHcEShHsw But I like this one better…. http://www.youtube.com/watch?v=4CK4z4MDXuE

  25. WRITE IN NOTEBOOK… • We need O₂ for 2 reasons… • Respiration: Using our lungs to breathe in oxygen and breathe out carbon dioxide • Cellular Respiration: A chemical reaction that uses oxygen to break down stored energy from glucose; happens in cells

  26. So what happens when you breathe? BUT IT’S NOT THIS SIMPLE…. Oxygen (O2) goes in Carbon dioxide (CO2) goes out

  27. Discovery Ed Video • Cellular Respiration: Releasing the Stored Energy in Glucose • Think about these questions when watching: • What happens to glucose in the presence of oxygen? • How are photosynthesis and cellular respiration related?

  28. Respiration – Write in Notebook • Respiration is the process that breaks down sugar to make energy. It happens in animal cells and plant cells. • Cellular Respiration Equation: Oxygen + Sugar (O2) (C6H12O6) Reactants (what goes in) Products (what comes out) Water + Carbon Dioxide (H2O) (CO2) + ENERGY!!

  29. So where does all this oxygen come from?? • Remember, it is due to green plants doing PHOTOSYNTHESIS!

  30. Which of the following statements are true? • Photosynthesis is like respiration in reverse • Photosynthesis produces CO2 • Photosynthesis needs sunlight

  31. Copy the TWO statements that are true in your notebook • Photosynthesis is like respiration in reverse • Photosynthesis produces CO2 • Photosynthesis needs sunlight

  32. Respiration is the opposite of Photosynthesis!

  33. What is Transpiration? • https://www.youtube.com/watch?v=8da0eyeTzBo&list=UUQNcNznbrboyLfH5y4X73Qw • https://www.youtube.com/watch?v=OBsdQWMnj9s&list=UUQNcNznbrboyLfH5y4X73Qw

  34. Transpiration Poster

  35. Transpiration • Outside of Leaves: epidermis, waxy cuticle and stomata = prevent water loss. • Guard cells surround and control the size of the openings in the stomata (control transpiration) • The loss of water through the stomata is called transpiration.
