Light Reaction (involves the sun)
The roots suck up water from the ground, into the chloroplasts. In there, the water is sun-heated and gets split into hydrogen, oxygen and ATP. The oxygen then gets released for us to breath and the hydrogen is put to a different part of the leaf.
Dark Reaction (doesn't involve the sun)
After the hydrogen gets to the other part of the leaf, the CO2 (carbon dioxide), that we breath out, mixes with the hydrogen and gets fused using ATP, making sugar/starch.
Dark
royal blue is light and navy blue is dark
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
Dark Reaction
light reactin produce atp and nadph2 .this two substance will use for the stap of dark reaction
1.what is the difference between light and dark reaction? 2.explain dark and light reaction?
The difference between light and dark is a rather complicated topic. It involves, with light, their being certain wavelengths present. With darkness, there are no wavelengths present.
What is the difference between the light dependent and the dark reactions of the calvin cycle?
color
Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)
The bi product of the light reaction triggers the dark reaction.
The light is used for photolysis of water and converting the radiant energy into chemical energy. These energy rich compounds during dark reaction assimilate carbon from carbon dioxide to form carbohydrates.
It is the light reaction. Then they moves to dark reaction

why light reaction of photosynthesis is essential before the dark reaction can procced?
There must be a light reaction first before dark reaction. This is so that there is something to be compared.
without ATP and (NADPH +H+) WE cannot run the dark reaction.and this molecules are produced from the light reaction.
