Thylakoids are disc-shaped structures which make up grana of chloroplasts. They are the site of light reaction(photo-chemical phase of photosynthesis) because they contain quantosomes within them lining their inner membrane. Quantasomes contain chlorophyll molecules which carry out photosnthesis.

What is the function of a thykaloid membrane?
Contain the necessary photosystems (P680, P700) and protein complexes (electron transport chain) for light-dependent reactions.
How is ATP made in the light reactions?
In the light reaction, when electrons are transferred from photosystem 1 to photosystem 2, it goes through an electron transport chain. This ETC pumps protons into the thykaloid. Those protons diffuse out of the thykaloid through ATP synthase which energizes a phosphate group to bond to ADP. This creates ATP.
Where in the plant cell does photosynthesis occur?
Within Chloroplasts.
Are ATP molecules made during the light-independent reactions of photosynthesis?
An electron transport chain is gone through when electrons are transferred from photosystem 1 to photosystem 2. ETC pumps protons through the thykaloid. Protons are diffused out of the thykaloid and through the ATP synthase.
What is photoactivation of chlorophyll?
The initial stage of [[photosynthesis in [[chlorophyll Molecules where the presence of [[light Energy raises the energy. It is the first event int he first phase of photosynthesis which is light-dependent reactions.it happens at the thykaloid. Chlorophyll molecules capture light energy and becomes energized electrons(e-).
Where do the lightdependent reactions take place?
on the thykaloid membranes of the chloroplast.
What are the insides of a thykaloid membrane?
The thylakoids of a chloroplast contain the phytosynthetic pigments, such as chlorophyll.

What is responsible for capturing the light in photosynthesis?
pigments (original answer) Technically whoever wrote pigments is right, BUT it is the chloroplasts in the Thykaloid Membranes that capture the light and the process goes from there.

Within Chloroplasts.

What is the possible result of photosynthesis?
Cells produce energy through the chloroplasts, which originated from light. There are two reactions: one in the thykaloid, which is known as the light reaction, and one in the stroma, which is called the Calvin Cycle. the Calvin Cycle is known as the sugar factory.

Where does electron transport chain happen?
It occurs in the inner mitochondrian membrane. it is most commonly used to produce energy in the mitochondria, however, it can occur in chloroplasts (in which case, it would occur in the thykaloid)
What are the Light reactions steps?
As light is absorbed the electrons pass through the pigments. The energy passes through the PEA molecules in the thykaloid membrane. The energy moves through the electron transport chain. The energy has been replenished. Water splitting occurs in the Calvin Cycle. All of the energies are paired with a H plus ion.
Difference of chemiosmosis in chloroplasts and mitochondria?
Well, I know that in mitochondria, protons are pumped from the matrix to the intermembrane space; however, in chloroplasts, protons are pumped from the stroma to the thykaloid space.I am not sure if that is the only difference, though ^^'
