Why oxygen is released during photosynthesis?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose.
Oxygen is released as a byproduct.
In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process..
Where does the oxygen come from in photosynthesis?
The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.
What color has the highest rate of photosynthesis?
redThis investigation will be focusing on which wavelengths of visible light, colour of light, has the highest rate of photosynthesis. It is safe to assume that green would have to lowest rate of photosynthesis because it is reflected by the leaves of plants and red/violet would have the highest rate of photosynthesis.
Does photosynthesis require oxygen?
By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. … Oxygen is required to do this.
Why do plants grow best in white light?
Plants use all colors and that is exactly what white light provides. Because it provides all colors, and because it is the light that plants receive out in nature, white light is the best light for plants. High pressure sodium and metal halide bulbs have been growing plants successfully for decades.
Is white light better than blue light for photosynthesis?
White light is actually made by combining other colors on the spectrum such as red, green, and blue. Therefore white light will actually be much more beneficial for the photosynthesis process than yellow light.
In which Colour of light photosynthesis is minimum?
green lightSo that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum. Minimum photosynthesis takes place in the green light. Minimum absorption of chlorophyll a occurs in the green region because plants themselves are green due to the pigment Chlorophyll.
Which light takes place photosynthesis?
Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
What color light is best for plant growth?
Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.
Is red or blue light better for photosynthesis?
light. In contrast, blue light is considered equally effective as green or red light at driving photosynthesis. Thus, while blue light can appear somewhat dim to us, it has high energy and is useful for plant growth applications.
How light Colour affects the rate of photosynthesis?
Hypothesis: The lights higher on the light spectrum, like blue, would have the fastest rate of photosynthesis because the energy is the highest. The green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as much as the other colors.
Where does the majority of oxygen come from?
Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
Why is red light best for photosynthesis?
The primary reasons why LED fixtures emit a lot of red are 1) red LEDs are among the most efficient at converting electricity into photosynthetic photons, 2) chlorophyll strongly absorbs red light, thus it is effective at photosynthesis, and 3) red LEDs are relatively inexpensive.
Why do plants absorb red and blue light the best?
Short answer: plant absorbs mostly “blue” and “red” light. … To do this, plants have pigment molecules which absorb the energy of light very well. The pigment responsible for Page 7 most light-harvesting by plants is chlorophyll, a green pigment.
In which light photosynthesis is maximum?
red lightMaximum photosynthesis occurs in red light. Light is absorbed by photosystem II that is membrane-bound. It absorbs infrared and red light. On the other hand, blue light is absorbed by chlorophyll and carotenoids but some carotenoids are not found in chloroplasts.
