Mitochonndria are cell organells related to respiration. Light reaction, on the other hand, occurs during photosynthesis in the chloroplasts. Thus, any part of a mitochondrion is not responsible for light reactions.
That is the dark reaction. It needs no light
The term "light reaction" does not really apply when speaking of mitochondria. Mitochondria are like furnaces. You put the wood in, light it, and it gives off heat. You put glucose into the mitochondria and the membranes facilitate the breakdown of that glucose to release the energy that was trapped in the carbon bonds. That energy is now stored as ATP. Mitochondria do not store energy, just as a furnace doesn't store heat. They process the fuel (glucose) to release energy--day or night. "Light reaction" is more aptly applied to photosynthesis, which does depend on light energy for the first part of the reaction.
The light-dependent reactions of photosynthesis occur in the thylakoid membrane of the chloroplast. Pigments like chlorophyll absorb light energy, which is then used to generate ATP and NADPH.

Photosynthesis occurs in the choloroplast, a organelle in the cell. More specifically: photosynthesis is divided into several steps. The first step/steps is the light reaction, or light-independent reaction. This happens to absorb the photons, and with it, the energy, from the sun. This part occurs in the thylakoid membranes of the chloroplast. The second part is the Calvin cycle, or the dark/ light-dependent reaction. This part takes the results of the first reaction, and change that energy that was captured into glucose. This occurs in the grana of the choloroplast.
I think it would be the mitochondria.
nope. only in the chloroplast. in that there are two cycles, the light reaction and the Calvin cycle Light reaction light is taken in the plant water from the roots is broken down oxygen is released from the plant leaves ATP and NADPH (a high energy electron carrier) is produced (carries hydrogen) Calvin Cycle CO2 is taken in ATP is used as energy NADPH is used to lower ativiation energy (after the calvin cycle, NADPH become NADP+)
Respiration occurs in the mitochondria of the cell, specifically in the inner membrane where the electron transport chain and ATP synthesis take place.
Light-independent reactions
No, but it is part of it.
Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP. dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.
The dark reaction, also known as the Calvin cycle, occurs in the stroma of the chloroplast. It does not require light to proceed and is responsible for capturing carbon dioxide and converting it into sugars through a series of enzymatic reactions.
