Text of Photosynthesis & Cellular Respiration - Mrs. Photosynthesis & Cellular Respiration . What is...

  • Photosynthesis

    & Cellular Respiration

  • What is Photosynthesis?

     The process of capturing and transforming the energy of sunlight into chemical energy

     Who Uses This Process?

     Plants (Plant Cell)

     Some Bacteria's

     Protists They make their

    own food!

  • Which Organelle inside the

    plant cell performs

    photosynthesis?

    Organelle: Chloroplast

    Why is it Green?

    Pigment called chlorophyll

    Chlorophyll – Contains photosynthetic membranes

    Converts light energy to chemical energy

  • Chlorophyll  Why are plants green?

     Light-absorbing chlorophyll molecules are present in thylakoid discs that fill the CHLOROPLAST

     Out of the entire spectrum of colors that makes up white light, chlorophyll absorbs both the red and blue.

     Green is reflected away, and is the color you observe.

  • What do you need for

    photosynthesis to take

    place?

     Sunlight

     Carbon Dioxide (Co2)

     Water ( H2O)

     Oxygen

     Glucose

  • Photosynthesis Equation

  • How does the water, carbon dioxide and

    sunlight enter the plant?

  • Guard Cell

    Guard cell walls have cellulose

    This causes the bow in the

    Guard cell and stomate opens

  • What is Photolysis?

     This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll;

     A type of photosynthetic pigment that converts the light to chemical energy.

     This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart.

     From this dissection of water, the oxygen is released as a by-product

  • Cellular Respiration

     Who uses the O2

    and C6H1206?

     Which organelle:

    Mitochondria!!

     Found: Animal

    Cells

  • Photosynthesis Respiration

    Energy Storage

    Chloroplasts

    Plant Cell

    Sunlight

    Water

    Carbon Dioxide

    Energy

    Release

    Mitochondria

    Animal Cells

    Glucose

    Oxygen

  • Photosynthesis Respiration

    Glucose +

    Oxygen +

    Water

    C6H1206 / 02

    6H20 + 12H20

    Light

    C6H1206 + 602

    Energy- ATP

    Carbon

    Dioxide

    Water

    C6H1206 + 602

    +6H20

    Equals

    6C02 + 12H20
