What kind of energy does a plant use in photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What kind of chemical is used in photosynthesis?
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it.
How is water used in the photosynthesis process?
The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive.
How are glucose and starch used in photosynthesis?
Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That’s why some foods that we eat, like rice and grains, are packed with starch!
What is the formula for the process of photosynthesis?
If we were to write a formula for photosynthesis, it would look like this: 6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
Why is oxygen released in the process of photosynthesis?
Even the oxygen that is released serves another purpose. Other organisms, such as animals, use oxygen to aid in their survival. If we were to write a formula for photosynthesis, it would look like this: The whole process of photosynthesis is a transfer of energy from the Sun to a plant.
How is light energy converted into chemical energy?
Light energy from photons is converted into chemical energy in photosynthesis. The energy of photons is used to split water molecules which releases energetic electrons. Energy from the electrons drive the production of molecules of ATP and NADPH.
