Photosynthesis
This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

In photosynthesis do plants absorb energy from the sun?
Plants don't really absorb energy, but they do use the energy of the sun's light to convert water and carbon dioxide into glucose, which is a form of chemical energy. So yes, the sun's energy does enable plants to grow, but it isn't just absorbed in the same form.
What are four ingredients needed for photosynthesis?
you need water,carbon,chorophyll, and sunlight for a photosynthesis
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
Which pigment is directly involved in the light reactions of photosynthesis?
The pigment directly involved is the green pigment called 'chlorophyll' and is found in the chloroplats.
Photosynthesis and cellular respiration are part of which cycle?
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.
The part of the open ocean that receives enough light for floating algae to carry out photosynthesis is called the euphotic zone or photic zone. This is the upper layer of the ocean where sunlight penetrates and supports photosynthetic activities of algae and other marine plants.
Oxygen is released into the atmosphere during which phase of photosynthesis?
Oxygen is released into the atmosphere during the light-dependent reaction phase of photosynthesis. This process occurs in the thylakoid membranes of chloroplasts when water is split, releasing oxygen as a byproduct.
What would happen to photosynthesis if there was no carbon dioxide?
Photosynthesis requires carbon dioxide as one of its essential inputs. Without carbon dioxide, plants would not be able to carry out the process of photosynthesis, resulting in a severe reduction in their ability to produce energy and oxygen. This would disrupt the entire ecosystem as plants are primary producers supporting the food chain.
Were the first organisms that released oxygen as a by-product of photosynthesis?
No, they were not Toxic was actually poinsonous to the Anaerobic photoautotrophs. However cyanobacteria (a.k.a pondscum) is believed to be the first bacteria to give off oxygen as a by-product of photosynthetic processes.
How does the tempurature affect the rate of photosynthesis?
The rate of photosynthesis in relation to temperature forms a bell curve.
At low temperatures the enzymes responsibility for photosynthesis have very little energy so the rate of photosynthesis is very slow. If it is cold enough for water to freeze it can be very harmful to a plant.
As the temperature increases, the enzymes get more energy so the rate of photosynthesis increases.
If it gets too hot the enzymes begin to lose their shape (denature). This means they are unable to function properly and the rate of photosynthesis decreases again. Also, at higher temperatures the stomata close to prevent water loss. This also stops gas exchange which slows photosynthesis even further. If it is hot enough for water to boil this can be very harmful.
What is the job of chloroplast in photosynthesis?
The chloroplast is responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis. It contains chlorophyll, the pigment that absorbs light, and the necessary enzymes to carry out the photosynthetic reactions.
What is meant by photosynthesis spiritually?
Spiritually, photosynthesis can be seen as a metaphor for transformation and growth. Just as plants convert sunlight into energy to fuel their growth, spiritually, photosynthesis can represent the process of harnessing positive energy or experiences to nourish the soul and encourage personal development and enlightenment.
The rows of light at the front of a stage are called foot.?
They are called footlights. They are used to provide a part of the illumination and to soften the heavy shadows made from overhead lighting.
they are set at floor level, that's how they get the name 'footlights'.
Hope this helped :)
The product of photosynthesis needed by both plants and other organisms for cellular respiration is glucose. Glucose is a sugar molecule that serves as a source of energy for living organisms. It is produced during photosynthesis in the chloroplasts of plant cells.
The flat green organ adapted to collect as much light as possible to make food for the plant is called a leaf. Leaves contain chlorophyll, a pigment that absorbs sunlight for photosynthesis, allowing the plant to convert the light energy into chemical energy in the form of sugars.
Is CO2 given off during photosynthesis?
Plants absorb carbon dioxide by photosynthesis. They release carbon dioxide, usually at night, through respiration.
Photosynthesis is a process that uses the energy of light (photo-) to fuel the conversion of carbon dioxide and water into sugars that can then be converted into plant material (-synthesis) as well as releasing oxygen. In the process of converting the sugars created by photosynthesis into other plant material, plants consume some oxygen and release carbon dioxide. This is particularly noticeable at night or when light is low and hence photosynthesis is not occurring. This process where they release carbon dioxide instead of taking it in is known as respiration. In general, the plants release more oxygen during photosynthesis than they consume in respiration and likewise consume more carbon dioxide in photosynthesis than they release in respiration.
How does temperature in a luminol reaction affect light produced?
If the temperature of the glow stick (chemiluminescence) is warmer, it releases a brighter glow and has a shorter reaction time. If the temperature of the glow stick is colder, it releases a dimmer glow but has a longer reaction time.
Lower temperatures slow reaction rates and release less light intensity then higher temperatures.
Why do animals depend on photosynthesis?
Plants produce oxygen for use to breathe, and in return the plants take in our carbon dioxide. The CO2 (carbon dioxide) joins with water and solar energy to produce glucose for the plants to live. So humans and plants need each other to live.
Is one mole of cadmium heavier than one mole of gold?
No, one mole of gold is heavier than one mole of cadmium. Gold has a higher molar mass than cadmium, which means that one mole of gold contains more atoms and therefore weighs more than one mole of cadmium.
The overall equation for cell respiration?
The overall equation for cellular respiration is: Glucose (C6H12O6) + Oxygen (6O2) --> Carbon Dioxide (6CO2) + Water (6H2O) + Energy (ATP). The process involves the breakdown of glucose to release energy, with carbon dioxide and water produced as byproducts.
Name the leaf cell that carry out photosynthesis?
Chloroplasts are the leaf cells that carry out photosynthesis. These organelles contain chlorophyll, a pigment that captures light energy and converts it into chemical energy through the process of photosynthesis.
What do plants take in during respiration?
Water is taken in and utilized by plants for photosynthesis.
