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.

What happens during energy conversion?
There is no physical connection between the primary and secondary of a transformer. A transformer is essentially 2 laminated coils of wire interwoven with each other. The magnetic field created in the primary coil is induced into the secondary coil creating voltage on the secondary side.
What contains chlorophyll that changes sunlight into food?
The leaves of plants, that's why their green.
endergonic is a reaction under which energy is stored in a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.

6 CO2 + 6 H2O = C6H12O6 + 6 O2
6 moles of CO2 are indicated, so...
6 x 6.022 x 10^23 = 3.6132 x 10^24 molecules of CO2
though I believe you are only looking for the number of moles (6)
What factors affect the process of cellular respiration and photosynthesis?
Factors affecting cellular respiration include substrate availability, oxygen levels, and temperature. For photosynthesis, factors include light intensity, carbon dioxide levels, and temperature. These factors can impact the efficiency and rate of each process in cells.
What organisms use energy from photosynthesis?
Most plants perform photosynthesis.
The energy is given to the plants, but when the plant is eaten, is transferred into the consumer (ex. cows grazing, vegetarians)
Once the consumer is eaten (ex. cows make beef, I certainly hope the vegetarians aren't eaten), the energy is transferred into the consumer of that organism.Or any living organism except the plant eaten.
What structure does the chloroplast contain that is responsible for photosynthesis?
Chlorophylls, in the thylakoid membranes, and the stroma of chloroplasts.
Why do light reactions only occur during daylight?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
Is there more energy before or after photosynthesis?
Neither. Energy is neither created nor destroyed it only ever changes form. This is the First Law of Thermodynamics.
However, if you want to talk about energy that is available to the cell in a usable form then there is more of that at the end photosynthesis.
What part of a plant is green and traps sunlight?
It is both a pigment called chlorophyll and an organelle called a chloroplast that captures light energy and uses it to make food. When making the plant food (glucose) the chloroplast gives the plant a green color, especially in the leaves and stem.
What are the 3 end products of photosynthesis?
The three end products of photosynthesis are glucose (sugar), oxygen, and water. During photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose and release oxygen as a byproduct.
In which parts of a plant does most photosynthesis take place?
What part of the plant dose the most work in phothsynthesis
What happens during the 2nd step of photosynthesis?
The cell uses captured energy to make sugars. It needs H2O and CO2. The materials move to chloroplasts. The chemical reactions result in glucose and oxygen production. Glucose is used by the plant for energy.
In what organelle of the cell is photosynthesis carried out?
Photosynthesis is carried out in the chloroplasts of plant and algal cells. Chloroplasts contain chlorophyll, a green pigment that captures light energy to convert water and carbon dioxide into glucose, releasing oxygen as a byproduct.
A reaction in living things that turns sugar and oxygen into carbon dioxide?
The process is called photosynthesis. It occurs in most green plants (mainly in the leaves).
Simplistically: Plants use atmospheric carbon dioxide and combine it with water in the presence of sunlight to produce glucose (sugars) and water.
The plants then use the sugars to "fuel" metabolic and growth functions; during the process of "respiration" the sugars are broken down releasing energy and oxygen - the latter is expelled by the plant.
The chemical process is as follows:
6CO2 + 6H2O + light energy = C6H12O6 + 6O2

What are the four basic things needed for photosynthesis to happen?
The four basic things needed for photosynthesis to occur are sunlight, water, carbon dioxide, and chlorophyll. Sunlight is the source of energy, water is needed to provide hydrogen electrons, carbon dioxide is used as a carbon source, and chlorophyll is the pigment that captures light energy for the process.
What substances are produced in photosynthesis and respiration?
Glucose and water is produced in photosynthesis.ATP is produced in respiration
What are required for plant to begin photosynthesis?
In order for a plant to begin photosynthesis, it needs energy from the sun, water and nutrients from the soil
What does messenger RNA do during photosynthesis?
copy the coded message from the DNA and carry it into the nucleus
Why is the presence of chlorophyll necessary for plants survival?
Chlorophyll is necessary for plants' survival because it is a pigment that allows them to photosynthesize, converting sunlight into energy. This process is vital for the plant to create its own food and grow. Without chlorophyll, plants would not be able to produce the energy needed to survive.
Is ATP a net product or reactant of photosynthesis?
In the chloroplast, the thylakoid membranes are the sites of the light reactions, whereas the Calvin cycle occurs in the stoma. The light reactions use solar energy to create ATP and NADPH, which supply chemical energy and reducing power, respectively, to the Calvin cycle. The Calvin cycle incorporates CO2 into organic molecules, which are converted to sugar.
What color do thylakoids turn to because they contain chlorophyll?
Most likely chlorophyll (but not always) and it will be green.
