The Effects of Lights on Plants Tim Langley Biology 101 Research project
Plants Importance to the World ,[object Object]
Plants are the only organism that produces its own food
Plants get their energy directly from the sun
Plants are the only organisms that produce oxygen, and we would suffocate without them,[object Object]
All of the oxygen on earth is a product of photosynthesis
Photosynthesis is an endergonic redox process
Occurs in two stages: the light reactions and the Calvin cycle
Takes place in the thylakoid membranes of the chloroplasts,[object Object]
Chloroplasts  ,[object Object]
The structure is mainly made from the fluid, Stroma, and the Granum which is in the form of thylakoid sacs
Contains three types of pigments: Chlorophyll a, chlorophyll b, and carotenoids
Light energy is captured by the chlorophyll in the chloroplasts and transferred into chemical energy,[object Object]
An excited electron is unstable and will drop back to the ground state and release its excess energy in the form of heat and fluorescence
Fluorescence is the afterglow of an isolated chlorophyll ,[object Object]
Linear Electron Flowthe flow of electrons through the photosystems A photon is absorbed by a pigment molecule in the light harvesting complex, exciting an electron As one electron falls back to ground state, another one rises  This continues until the energy reaches the pair of chlorophyll a molecules in the reaction center complex in photosystem II An enzyme splits water in photosystem II into electrons, hydrogen ions, and oxygen The splitting of water molecules facilitates the flow of electrons through the electron transport chain to photosystem I to replace the electrons that were excited by light energy ATP is then synthesized from the energy created from the movement of electrons Light energy is transferred from the light harvesting complex pigments to the reaction center complex of photosystem I Photoexcited electrons move from the primary electron receptor of photosystem I to the second electron transport chain This is a light dependent reaction, creating NADPH and ATP which are then used in a light  independent reaction, also known as the Calvin cycle

  • 18.
  • 19. Pigments absorb different wavelengths of light
  • 20. The absorption of different wavelengths changes the colors of the pigments
  • 21. Leafs are green because they absorb red, and violet-blue light and they reflect green light
  • 22. Light can only perform work if its absorbed by the chloroplastsA prism can bend light of different wavelengths at different angles
  • 23.
  • 24. Wavelengths are the distances between the crests of electromagnetic waves
  • 25. The wavelengths range from less than a nanometer to more than a kilometer
  • 26. Visible light is from 380nm to 750nm in wavelength
  • 27. The amount of energy a photon has is related to how long the wavelength is
  • 28.
  • 29. Photoperiodism The reaction of plants in relation to the length of the day Plants use it to measure the seasons and to coordinate seasonal events such as flowering Plants can be described in relation to their photoperiod responses as short-day, long-day, and day neutral The length of daylight effects vegetative growth and reproductive activities in plants The length of darkness a plant experiences plays a more crucial role in whether a plant flowers or not
  • 30.
  • 31. Short day plants only form flowers when the length of the day is less than about 12 hours
  • 32. Most spring and fall flowering plants are short day plants
  • 33. Chrysanthemums, poinsettias, and goldenrods are examples of short day plantsThe chrysanthemum is in demand all year, which is why florist have to regulate their flowering using artificial lighting
  • 34.
  • 35. These flowers only bloom when they receive more than 12 hours of light each day
  • 36. The best time of the year for long day plants to flower is late spring or early summer, when the days are longer (this is opposite in the southern hemisphere)
  • 37. Many garden vegetables are long day plants such as potatoes, lettuce, and barleyAfter the summer solstice days become shorter, and long day plants are harvested shortly after.
  • 38.
  • 39. They flower regardless of day length, but flower earlier and more often with longer days
  • 40. More often, the age of the plant, and temperature around it effect flowering
  • 41. Beans, tomatoes, and roses fall into the category of day neutral plantsRoses are the most popular day neutral flowers
