It's a true and false question, the answer is: False
False. False.
Chlorophyll is held in the thylakoid membranes within the chloroplasts of plant cells. Thylakoid membranes are where the light-dependent reactions of photosynthesis occur.
Light reactions occur in the thylakoid membranes of the chloroplast. Pigment molecules such as chlorophyll absorb light energy and transfer it to reaction center proteins, initiating a series of electron transfer reactions that generate ATP and NADPH as energy carriers for the Calvin cycle.
The light reactions occur in the thylakoid space, which can also be called the granum.
Light dependent reactions occur in the thylakoid membrane of the chloroplasts in photosynthetic organisms. The products (ATP and NADPH) are used in the second stage of photosynthesis, which is called the Calvin Cycle. (Oxygen is given off as a "waste" product - lucky for us!)
The light-catching membranes on a chloroplast are called thylakoid membranes. These membranes contain chlorophyll and other pigments that capture sunlight during photosynthesis to convert it into chemical energy. The thylakoid membranes are arranged in stacks called grana and are the sites where the light-dependent reactions of photosynthesis occur.
Chlorophyll is located in the chloroplasts of plant cells, specifically in the thylakoid membranes where the light-dependent reactions of photosynthesis occur.
The stroma and grana are portions of a chloroplast. The stroma is the fluid-filled space surrounding the thylakoid membranes where the Calvin cycle reactions occur, while the grana are stacks of thylakoid membranes where light-dependent reactions take place through the presence of chlorophyll.
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts, while the light-independent reactions (Calvin cycle) occur in the stroma of chloroplasts.
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts, specifically in the grana. The grana are stacks of thylakoid membranes where the light-dependent reactions take place. The stroma, on the other hand, is the fluid-filled space surrounding the grana where the Calvin cycle (light-independent reactions) occurs. So, the light-dependent reactions primarily occur in the grana, not the stroma.
Within Chloroplasts.
The reactions of photosynthesis take 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.
