What is light energy used for in photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Is light energy photosynthesis or cellular respiration?
How are photosynthesis and cellular respiration connected?
Photosynthesis | Cellular Respiration (Aerobic) | |
---|---|---|
Function for the organism | Use light, water, and carbon dioxide to create food for the organism in the form of sugar (glucose) | Use glucose to make a form of energy the organism can use in cellular processes (ATP) |
What is light and photosynthesis?
Photosynthesis is the process in which light energy is converted into chemical energy. Using the energy of light, carbohydrates such as sugars are synthesised from carbon dioxide and water. The name photosynthesis is derived from the Greek words, photo for ‘light’ and synthesis meaning ‘putting together’.
Is light is needed photosynthesis or respiration?
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).
What role does oxygen play in photosynthesis and cellular respiration?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
Does photosynthesis produce oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Which is true of photosynthesis and cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
What color light is best for photosynthesis?
green light
The majority of green light is useful in photosynthesis. The relative quantum efficiency curve (Photo 1) shows how efficiently plants use wavelengths between 300 and 800 nm. Green light is the least efficiently used color of light in the visible spectrum.
Does more light mean more photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.
Which occurs in the presence of oxygen?
aerobic respiration
Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.
What role does o2 play in cellular respiration?
Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.
How do humans benefit from photosynthesis?
Food is the source of energy and is also needed to provide nutrients. Since human beings cannot produce their own food, they are dependent on plants, carrying out photosynthesis, for food. Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere.
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.
Which is a by-product of photosynthesis and respiration?
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4). Figure 4.
How are carbon dioxide and water used in photosynthesis?
Photosynthesis. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4).
How are sugars produced in photosynthesis used by plants?
Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes.
