  12. What is the LT? Agenda • BW / LT • Virtual Lab • Formative Review of LT • Formative for LT 20 on Firday

  13. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis.

  14. PHOTOSYNTHESIS • Autotrophic Process: Plants and plant-like organisms make their energy (glucose) from sunlight. • Stored as carbohydrate in their bodies. • 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2

  15. Why is Photosynthesis important? • Makes organic molecules (glucose) out of inorganic materials (carbon dioxide and water). • It begins all food chains/webs. Thus all life is supported by this process. • It also makes oxygen gas!!

  16. Photosynthesis-is the start to ecological food webs!

  17. Photo-synthesis means"putting together with light." • Plants use sunlight to turn water and carbon dioxide into glucose. Glucose is a kind of sugar. • Plants use glucose as food for energy and as a building block for growing. • Autotrophs make glucose and heterotrophs are consumers of it.

  18. How do we know that plants make carbohydrates from just carbon dioxide water and light energy? Experiments! • For example: Jan Baptisa van Helmont (1648) planted a willow branch weighing 5 pounds into 200 pounds of soil and then after 4 years the tree weighed 169 lbs. and the soil was still nearly 200 lbs.

  19. As can be seen from the equation for photosynthesis, the wood, bark, and root came from water and carbon dioxide. Photosynthesis Carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6CO2 + 6H2O + energy  C6H12O6+ 6O2

  20. Plants in Action Check it! What is the process that uses the sun’s energy to make simple sugars?

  21. Plant leaves have many types of cells!

  22. Plant Cells

  23. The photograph below is an elodea leaf X 400. Individual cells are clearly visible. The tiny green structures within the cells are chloroplaststhis is where photosynthesis happens.

  24. Chloroplasts make the sugars!

  25. Leaves are green because they contain the pigment: Plants chlorophyll Leaves have a large surface area to absorb as much light as possible "Thanks for the Glucose!"

  26. Chloroplasts make the oxygen too!

  27. StomaThis opening how plants exchange gases!Check it! Can you name the two important gases that go in and out of the leaves? Why are the stomata located on the underside of leaves?

  28. PHOTOSYNTHESIS • Absorbing Light Energy to make chemical energy: glucose! • Pigments: Absorb different colors of white light (ROY G BIV) • Main pigment: Chlorophyll a • Accessory pigments: Chlorophyll b and Carotenoids • These pigments absorb all wavelengths (light) BUT green!

  29. PHOTOSYNTHESIS • Why do we see green? • Green color from white light reflected NOT absorbed • Chloroplast: organelle responsible for photosynthesis • Chlorophyll: located within Chloroplast • Green pigment

  30. Visible light is only a small part of the electromagnetic spectrum (all forms of light).

  31. LIGHT behaves as if it were composed of "units" or "packets" of energy that travel in waves. These packets are photons. • The wavelength of light determines its color.

  32. Chlorophyll: A Light Absorbing Pigment The Solar Panel Chemical!

  33. Glucose provides the energy and carbon needed to make other plant materials like wax and proteins. Photosynthesis

  34. Oxygen and Sugar!

  35. In plants and simple animals, waste products are removed by diffusion. Plants, for example, excrete O2, a product of photosynthesis.

  36. EQUATION FOR PHOTOSYNTHESIS WATER OXYGEN 6CO2 + 6H2O + ENERGY C6H12O6 + 6O2 CARBON DIOXIDE GLUCOSE

  37. The end!

  38. PHOTOSYNTHESIS • 2 Phases • Light-dependent reaction • Light-independent reaction • Light-dependent: converts light energy into chemical energy; produces ATP molecules to be used to fuel light-independent reaction • Light-independent (Calvin Cycle): uses ATP produced to make simple sugars.

  39. PHOTOSYNTHESIS • Light-dependent reaction (LIGHT Reaction) • Requires light • Occurs in chloroplast (in thylakoids) • Chlorophyll (thylakoid) traps energy from light • Light excites electron (e-) • Kicks e- out of chlorophyll to an electron transport chain • Electron transport chain: series of proteins in thylakoid membrane • Bucket brigade

  40. PHOTOSYNTHESIS • Light-dependent reaction (LIGHT Reaction) • Energy lost along electron transport chain • Lost energy used to recharge ATP from ADP • NADPH produced from e- transport chain • Stores energy until transfer to stroma • Plays important role in light-independent reaction • Total byproducts: ATP, NADP, O2

  41. PHOTOSYNTHESIS • How did we get O2 as a byproduct?! • Photolysis: replaces lost electrons by splitting water

  42. Sun Light energy transfers to chlorophyll. • At each step along the transport chain, the electrons lose energy. Chlorophyll passes energy down through the electron transport chain. Energized electrons provide energy that to ADP splits H2O bonds P forming ATP H+ NADP+ oxygen released NADPH for the use in light-independent reactions

  43. PHOTOSYNTHESIS • Light-independent reaction (Dark Reaction) • Does not require light • Calvin Cycle • Occurs in stroma of chloroplast • Requires CO2 • Uses ATP and NADPH as fuel to run • Makes glucose sugar from CO2 and Hydrogen

  44. Bell Work 1-27-2016 • Write the equation for photosynthesis. • Cut apart the sort you were given at the door then display equations for photosynthesis and cellular respiration. • Use an electronic devise to research 3 things that affect the rate of photosynthesis. LT 22 I can explain the process of cellular respiration.

  45. What is the LT? Agenda • BW / LT / pass out Plickers • Check sort • Finish the Cellular Respiration foldable • Kahoot
