The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
What else can I help you with?
How many times does the Calvin cycle turn during photosynthesis?
The Calvin cycle turns once during photosynthesis.
Which organisms undergo both photosynthesis and cellular respiration?
Plants, algae, and cyanobacteria are examples of organisms that can undergo both photosynthesis and cellular respiration. During the day, they perform photosynthesis to produce energy from sunlight, and at night or during times of low light, they switch to cellular respiration to generate energy from stored carbohydrates.
How many times did photosynthesis evolve in the history of life on Earth?
Photosynthesis evolved multiple times in the history of life on Earth. It is believed to have evolved at least two separate times, leading to different types of photosynthetic organisms.
How do the potatoes underground contain starch when photosynthesis occurs in the green leaves above?
The product of photosynthesis is a sugar called glucose. Glucose is soluble in water and can therefore be moved round the plant to where it is needed in the plants vascular system. Thus the glucose is taken to the underground stems forming the potatoes and converted into its polymer form (starch) there.
How does a plant store sugars?
Plants store sugars in the form of starch, which is a complex carbohydrate. Starch is synthesized in the chloroplasts during photosynthesis and then stored in specialized storage organelles called amyloplasts. Plants can mobilize this stored starch to provide energy during times of need.
Are electrons are energized twice during photosynthesis?
Yes because there are two photosystems (clusters of chlorophyll) which is where the sunlight is absorbed from, the electrons are energized at both times because sunlight contains photons which are the molecules that energize the electrons in the first place
How many times does the Calvin cycle turn during photosynthesis?
The Calvin cycle turns once during photosynthesis.
What happens to excess glucose during photosynthesis?
Excess glucose produced during photosynthesis is stored in the form of starch in plant cells. This stored energy can be used later for growth, reproduction, or as a reserve for times when there is lower sunlight availability for photosynthesis.
Why phosphor screen is used in night vision goggles?
In a night vision tube, the object of the tube is to convert incoming light particles (photons) to electrons. The electrons are then multiplied many times by the microchannel plate inside the tube. It is these multiplied electrons that are the output 'signal'. However, since your eye cannot see electrons, they are converted back to visible light by way of the phosphor screen which 'lights up' when energized by the electrons.
Where do producers store chemical energy?
Producers store chemical energy in the form of glucose, which is produced through photosynthesis. Glucose is stored in the plant's cells for energy use during times when photosynthesis is not occurring.
Which organisms undergo both photosynthesis and cellular respiration?
Plants, algae, and cyanobacteria are examples of organisms that can undergo both photosynthesis and cellular respiration. During the day, they perform photosynthesis to produce energy from sunlight, and at night or during times of low light, they switch to cellular respiration to generate energy from stored carbohydrates.
Which occurs at all times photosynthesis or cellular respiration?
Cellular respiration occurs at all times in living organisms, while photosynthesis occurs only in the presence of light during the daytime. Cellular respiration is the process by which cells break down glucose to produce energy, while photosynthesis is the process by which plants convert sunlight into energy.
How many times did photosynthesis evolve in the history of life on Earth?
Photosynthesis evolved multiple times in the history of life on Earth. It is believed to have evolved at least two separate times, leading to different types of photosynthetic organisms.
What is AFC in capacitor?
According to the manufacturer, is the number of cycles of life that has the Capacitor. The times I resite be energized.
How are the products of photosynthesis stored and why?
Products of photosynthesis, such as glucose, are stored in the form of starch in plants. Starch is a complex carbohydrate that can be broken down into glucose when energy is needed for growth, reproduction, or other metabolic processes. Storing glucose as starch helps plants maintain energy reserves for times when sunlight is not available for photosynthesis.
Are electrons bigger than neutrons and protons?
Electrons are 1,836 times lighter than protons. A proton is 99.8% the mass of a neutron
Explain why at certain times of a day there is no movement of oxygen or carbon dioxide through stomata even though they are open.?
It might be that at certain times there is a balance between the amount of photosynthesis and the amount of cellular respiration going on. Photosynthesis produces the oxygen that respiration needs. Respiration produces the carbon dioxide that photosynthesis needs.
