What stage is sunlight needed in photosynthesis?
The first stage of photosynthesis is wherein water is necessary. Water is photochemically split into oxygen, electrons and hydrogen ions together with light reaction.
What are raw materials needed for photosynthesis and what are their products?
the chemical equation for photosynthesis is: water + carbon dioxide + sunlight = oxygen + glucose so the first three are the requirments and the last two are the final product of the process
What is the first molecule to provide electrons for photosynthesis?
Water 
Why are pigments such as chorophyll needed for photosynthesis?
Pigments like chlorophyll, capture light energy which is used for the first step of photosynthesis, the light dependent reaction.
How water is removed from plants?
First by soil-absorption, then by evaporation and photosynthesis.
What process is similar to photosynthesis?
Glycolisis is common to both.It is the first step.
What are the 3 things that are needed for photosynthesis?
Typical photosynthesis, ie, the formation of carbohydrates, requires carbon dioxide (from the air), hydrogen (usually from water) and sunshine. Of course a plant with chlorophyll-containing parts is also needed since this is where it all takes place.
First stage in photosynthesis?
the plant collects water, carbon dioxide, and light.
First found compount in photosynthesis?
the removal of hydrogen (H) atoms from water molecules
Why is water needed in photosynthesis?
It is a part of the process of how a plant produces glucose and other sugars in order to live. In order to photosynthesize, a plant needs water from what is in the air (measured by humidity) or from what it takes from the ground in its roots, or on its leaves when it rains, and carbon dioxide from the atmosphere. The plant uses these two elements to produce by products oxygen, which is released as a waste product to the atmosphere, and glucose, which is uses for energy. Specifically, water is needed for photosynthesis because it's electrons are used to replenish the lost electrons from the chlorophyll in photosystem II. The hydrogens from water are also used to make a proton gradient that powers the ATP synthase which is used to make ATP for the Calvin cycle. The oxygen is a waste product of the process.
How can you determine how much water is needed?
First you find out what it is needed for... then u ask this question
What is necessary for photosynthetic reactions to occur?
Carbon dioxide is one chemical that is needed in order for the metabolic reactions of photosynthesis to occur. The first stage of photosynthesis is a light reaction where energy from light is captured.
