Photosynthesis. What is Photosynthesis? Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into high energy sugars and oxygen.

PHOTOSYNTHESIS. Energy Stored in chemical bonds of compounds. Compounds that store energy: ATP, and NADPH. When bonds are broken, energy is released.

ATP Adenosine Triphosphate. It is the energy molecule of the body. The three phosphates are negative and want to break free of each other. ATP gives energy.

Presentation transcript:

Photosynthesis producer, autotrophs, and the main Ingredients to make lots of biomass

Photosynthesis: sunlight into chemical energy

Raw ingredients for Photosynthesis Leaf Pigment Light chloroplast

Leaf- specialized for light absorption Chloroplast- specialized for energy conversion: sun  H+ gradient energy  into ATP  carbs

Leaf

The above diagram show absorption of light by chlorophyll. Which wavelengths of light are absorbed? A. 400, 500, 600, 700 B. 400, 700 C. 450, 650 D. Yellow and Red E. Both C and D

Photosynthesis is not a very efficient process. Of the sunlight reaching the surface of a leaf, approximately how much is : A. 75% is evaporated B. 15% is reflected C. 5% is transmitted through the leaf D. 4% is converted to heat energy E. 1% is used in photosynthesis

What observations can you make about this molecule? Polar or non polar? Why?

What wavelength of light is most effective for photosynthesis in filamentous green alga? A.Violet and Blue B.Blue and Orange C.Yellow and Green D.Orange and Red E.Red and Violet

Double membrane- Which is more similar to cell membrane, inner membrane or outer? Stroma- Grana- Thylakoid- Where is chlorophyll found? Where is light absorbed? What happens to light when its absorbed?
