The thylakoid are sac like structures found in the chloroplast in stacks.The thylakoid membrane contains chlorophyll pigments and take part in the light dependent reaction of photosynthesis by trapping solar energy.
PS 1 is located on the non- pressed surfaces of the thyllakoid in the choloroplast
chloroplast more detailed it is quantosomes present in thyllakoid of chloroplast which absorb light energy
You would have a better system for photosynthesis, because of how Chlorophyll work and how thyllakoid membranes are stacked together so that productivity is increased. So, having the physical barrier enables better reaction conditions.
Leaves appear green because they contain chloroplasts that are green in color. The function of these chloroplasts are to absorb sunlight and convert it into energy for the plant to feed on. In order for us to be able to see an object, the object must reflect light and in this situation the chloroplasts reflect sunlight and leaves appear green.
