What else can I help you with?
The dark reactions occur within the thylakoid membranes true or false?
False. False.
What structure of the cell holds chlorophyll?
Chlorophyll is held in the thylakoid membranes within the chloroplasts of plant cells. Thylakoid membranes are where the light-dependent reactions of photosynthesis occur.
Where in the chloroplast do light reactions 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.
In which structure of chloroplast do the light-dependent reactions occur?
The light reactions occur in the thylakoid space, which can also be called the granum.
Where do light dependent reactions occur in photosynthesis?
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!)
What are the light catching membranes on a chloroplast?
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.
What is the Location of chlorophyll?
Chlorophyll is located in the chloroplasts of plant cells, specifically in the thylakoid membranes where the light-dependent reactions of photosynthesis occur.
In which part of a plan does photosynthesis happen?
Photosynthesis primarily occurs in the chloroplasts of plant cells, specifically within the thylakoid membranes and the stroma. The light-dependent reactions take place in the thylakoid membranes, where sunlight is captured and converted into energy. The light-independent reactions, or the Calvin cycle, occur in the stroma, using that energy to convert carbon dioxide into glucose.
What are stroma and grana portions of?
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.
Where do the different stages of photosynthesis occur in the cell?
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.
Does the light dependet reactions with stroma or granum?
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.
Where in the plant cell does photosynthesis occur?
Within Chloroplasts.
