Why is it better to have several small thylakoids stacked into one granum than to have one large thylakoid that occupies the same volume?

Well, since the thylakoid is the site in which the light dependent reactions occur, and ATP and NADPH are produced for the Calvin cycle it would be better to have stacks of them instead of one large thylakoid. Stacks of thylakoid would ensure more ATP and NADPH to be produced which in turn will mean more carbon fixation.

∙ 10y agoThe thylakoids are stacked in grana because it has proven adventagous and more efficient over time. The light reactions of photosynthesis require a membrane to work because of the chemical gradient of protons that has to be built up to power the ATP synthase. Having grana instead of lone thylakoids increases the surface area of membranes in which the light reactions can take place.

Role of pigments and photosystems in the capture of light energy?
thylakoid membrane The photosystems that capture light are located on the thylakoid membrane. The thylakoids are stacked to form grana.
Thylakoid disks are?
Stacked
What does the skeletal framework of the neck consist of?
The neck is composed of several vertebrae that are stacked together. The vertebrae work together to protect the spinal cord from injury.The skeletal framework of the neck consists of multiple stacked vertebrae. Sometimes an individual vertebra can pop out of place, causing pain. Chiropractic intervention can return bulging discs to their place.

What do plants use during photosynthesis?
Photosynthesis is the process in which plants changes energy from the sun into chemical energy. That being said, photons from the sun are absorbed in the plants chloroplasts. These photons excite electrons that are present in the interior of the chloroplast. Electrons are located inside complexes known as photosystems, which are located in the membrane of thylakoids. Thylakoids are flattened sacs that are stacked together within the chloroplasts to form granum. When these electrons are excited they are passed on from Photosystem II to Photosystem I in a complex process that allows H+ ions to cross into the thylakoid. As the electrons are used up at each Photosystem they have to be replaced. This is where water comes in. Water gets "Split" apart and the electrons from water are donated to the Photosystem. So during photosynthesis plants use sunlight, water (to replace electrons), and NADP+ (this is an electron carrier that carries electrons to different cycles).

What pigment is in thylakoids?
it is the group of 200-300 accessory photosynthetic pigment that are attached to the thylakoid and pass the light energy from one another until it reaches the reaction center. it is conical in shape for it has to absorb the maximum amount of light energy entering and it is embedded in the membrane( thylakoid).
Where is the granum found?
A grana is the plural of granum. A granum is a stack of thylakoids found in chloroplasts--they look like stacks of pancakes (thylakoids). Grana is multiple stacks of thylakoids found in chloroplasts in the cell. The light reaction of photosynthesis takes place in the thylakoids stacked in grana.
A place where light reactions occur?
The place where light reactions occurs are the grana. These are composed of thylakoid sacs that are stacked and embedded in the chloroplast.
What are closely stacked flattened sacks in a cell?
In a plant cell, these are the thylakoid stacks located in the chloroplast. One stack is called a granum. They aid in the photosynthesis process.

What do the chloroplast do in photosynthesis?
The chloroplast is where photosynthesis occurs. There are structures inside the chloroplast called thylakoids. These thylakoids are membranes with special proteins on them that carry out the light reactions of photosynthesis. These membranes are stacked (these stacks are called grana) in order to increase their surface area for the light reactions. The light reactions are responsible for producing NADPH and ATP which will be used for the Calvin cycle. Between the membranes of the chloroplasts and the thylakoid membrane lies the stroma. Here is where the Calvin cycle takes place. It is responsible for producing glucose from a series of chemical reactions. Essentially, the chloroplast is responsible for carrying out photosynthesis which converts light energy into usable chemical energy for most life on Earth.
