The place where light reactions occurs are the grana. These are composed of thylakoid sacs that are stacked and embedded in the chloroplast.
thylakoid membrane
There are three carbon dioxide, water, and sunlight.
light independent reactions take place in thylakiods- more specifically in the thylakiod membranes of chloroplasts.
divide into parts: light reactions and dark reactions
is this asking where they occur or when they occur?anyway, light reactions take place in the stroma, which are in the chloroplast of plant cell. these are the little things that make plants green. this type of reaction can only take place in plant and some protist cells, because photosynthesis does not occur in any other kind of cell. (light reactions are a part of photosynthesis.)
The light-independent reactions occur in the storm of the chloroplast. The light- independent reactions are "independent" from light so they can happen else where. The light-dependent reactions happen in the thylakoid membrane of the chloroplast where the light is absorbed, and the reactions depend on the light.
Photosynthesis takes place in the chloroplasts of plant cells. Specifically, the light-dependent reactions occur in the thylakoid membranes, while the light-independent reactions (Calvin cycle) occur in the stroma of the chloroplast.
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.
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 :)
it occurs in the chloroplast / stroma oh and light reactions can only occur in a plant and some protists because only plants and some protists can perform photosynthesis, and it is in this process which light reactions occur. other cells don't have chloroplast and stromas.
The light-dependent reactions will not occur.
The dark reactions take place in the Stroma of the chloroplast.
