The light-independent reactions are sometimes referred to as the dark reactions, though that term may be misleading as they do not actually require darkness to proceed. The term "light-independent" is used to emphasize that the reactions occur regardless of the amount of light present as long as the proper substrate compounds are available. Even this term can be criticized, however, as the availability of substrates in plants depends on photosynthesis, so the reactions cannot be said to be entirely "light-independent." Furthermore, the term "dark reactions" may be more accurate in CAM (Crassulacean acid metabolism) plants, which only take up CO2, which is necessary for the reactions to proceed, at night.
http://en.wikipedia.org/wiki/Light-independent_reaction
a photochemical reaction is one which relies on light energy, hence the word 'photo' like in photosynthesis where light is needed to make glucose and oxygen from water and carbon dioxide.
hence why photochemical reactions are 'light dependent'
these reactions need light for the reaction to take place
Because it needs the energy from the sun in order to progress. Hence the name (sun) Light dependent reaction

Because it doesn't directly require light. Interestingly, light independent reaction will not perform in dark because ATP and NADPH made during the light reaction are not made, so the second stage cannot proceed.
Because they do not require the presence of Light to occur.
Because the reaction does not require light in order to proceed.
they do not require light to take place.
I don't know D;
they do not require light to take place.
they don't need light
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
During the Light Independent Stage or second stage of photosynthesis.
Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose.

* the second phase of photosynthesis, that does not require the presence of light, during which ATP releases stored energy that is used to convert carbon dioxide molecules into sugars and other nutrients * The dark reactions of photosynthesis doesn't require the presence of light to photosynthesize. * 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. * there are 2 main stages in potosyntesis. the light reaction occurs only in the presence of light while dark reaction happens both when there is light and when it is dark.
Photosynthesis occurs in the chloroplasts of the plant cell. There are stacks of thylakoids called granum, surrounded by a soultion called stroma in here. The first part of photosynthesis, known as The Light Reactions, takes place in the thylakoid membrane. The second part, the Calvin Cycle, takes place in the stroma.
That is the second step. It is called dark cycle
It is the second step of photosynthesis. It does not need light
Light-independent reactions
Photosynthesis is typically divided into two stages: 1) Light-dependent reactions, where light energy is absorbed by chlorophyll to produce ATP and NADPH, and 2) Light-independent reactions (Calvin cycle), where ATP and NADPH are used to convert carbon dioxide into glucose.
Photosynthesis is performed in two stages:Light reactions (or light-dependent reactions): Energy from sunlight is required.Dark reactions (or light-independent reactions): No sunlight is required. However, energy formed by the light-dependent reactions is needed.
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
1st-Light reaction 2nd-Dark reaction
During the Light Independent Stage or second stage of photosynthesis.
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.
The Light Dependent process and then the Light Independent process (known as the Calvin Cycle).
There are two products. Those are NADPH and ATP.
