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 simple sugar formed from photosynthesis produces the vast majority of what chemical for humans?
Glucose from photosynthesis provides the vast majority of chemical energy to living things.
What process transfers light energy to chemical energy in a green house?
Photosynthesis, same as outside the green house.
So why do we use green houses?
The green house is used to raise the temperature so that the plants start growing and are not killed by cold. It does this is two ways, by constricting air flow and blocking infrared light.
The major part of this is that outside the green house, when the soil absorbs solar energy and turns it into heat, the air will transport that energy away which cools the soil and the plants growing in it. In the green house the warm air is trapped.
To some (small) extent glass will block ultraviolet and infrared rays more than visible light. This stops harmful UV rays from hitting the plants, and it traps the infrared heat emissions from the plants inside the green house.
Actually there is less useful sun light energy reaching the leaves within a green house than if the plants were outside it (try sunbathing under glass) but better control of temperature and humidity allows the plant to grow better anyway.
Do the carnivorous plants contain chloroplasts although they are meat-eating?
Carnivorus plants fulfill nitrogen requirements through eating organisms.They should conduct photosynthesis to fulfill carbon requirement.
Is Photosynthesis is the main process by which carbon dioxide moves from the atmosphere to biomass?
no
What part of a plant cell the Light reaction takes place?
The light reaction of photosynthesis takes place in the thylakoid membranes of the chloroplast in plant cells. This is where light energy is converted into chemical energy in the form of ATP and NADPH, which are essential for the later stages of photosynthesis.
What are the products of the Calvin cycle and how are they usd?
The only product of the Calvin Cycle is 1 molecule of glucose every two turns. It is used to begin the process of Cellular respiration through Glycolysis and is basically used for food to create ATP.
How does an ATP become an ADP in photosynthesis and what is released in the process?
When producing diPGA by PGA. Energy is released there by ATP
A tissues transport water and sugar in plant is?
The tissue responsible for transporting water and nutrients in plants is the xylem. Xylem tissue is made up of specialized cells called tracheids and vessel elements, which form continuous tubes for water and mineral transport from the roots to the leaves. Additionally, sugar transport in plants is facilitated by the phloem tissue, which transports sugars produced during photosynthesis to different parts of the plant for growth and energy.
What molecules do plants take in to begin the Calvin cycle?
Plants take in carbon dioxide from the atmosphere to begin the Calvin cycle. They also use ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) molecules, which are generated during the light-dependent reactions of photosynthesis, to power the Calvin cycle.
Does the rate of photosynthesis will decrease at a very temperature Why?
The rate of photosynthesis depends on temperature the same way enzymes depend on temperature.
Photosynthesis involves enzyme assistance. Enzymes are biological catalysts that speed up chemical reactions.
Enzymes are affected by pH and temperature. If the pH is too acidic or basic, enzymes will be denatured (which means they will change shape and not be able to catalyze reactions as well or entirely).
Same goes for temperature. If the temperature is too cold or too hot, the enzymes might deactivate, or their efficiency will be inhibited.
So, if the temperature of the organism's environment is too high or low, the rate of photosynthesis will decrease because the enzymes aren't working properly.
On the other hand, if the temperature is optimal for enzyme activity, the rate will increase, as production is at its high.
What are benefits of photosynthesis to human beings in reference to examples?
photosynthesis remove carbon dioxide that we breathe out and factories make, this helps the environment therefore it helps you as you are less likely to have diseases. Photosynthesis also slow down water reaching the river (as they need water for photosynthesis) this help us from floods.
On a label NPK fertilizer is written What does this expression mean?
N stands for Nitrogen.P and K stands for phospharus and pottasium respectively.They are elements in fertilizer.
Does photosynthesis occurs in watermelon?
yes photosynthesis occurs in a watermelon because: a watermelon is officially a berry, and the berry grows on a plant, the plant itself is green, contains chlorophyll, so therefor photosynthesis takes place.
Where does the energy come from in photosynthesis to rearrange the atoms?
It comes from light. Light energy is absorbed
Specifically in which organelle does photosynthesis happen?
Photosynthesis takes place in the chloroplasts. The organelles are only found in plant cells and some protists such as algae.
Is it true of false that both respiration and photosynthesis take place in some plant ells?
Yes it is true. Both of them happening in cells.
Which part of photosynthesis can occur even when there is no light?
That is the dark reaction. It needs no light
Which plant pigment traps most of the light energy used in photosynthesis?
chlorophyll b traps most of the light energy used in photosynthesis.
