Chlorophyll absorbs blue and red light most strongly. Green and yellow light are not effectively absorbed by photosynthetic pigments in plants. Light of these colors are either reflected by leaves or passes through the leaves. That is why plants are green. The chlorophyll is stored in the chloroplast. The stroma is a fluid inside of the chloroplast where reactions occur and starches (sugars) are created. One thylakoid stack is called a granum. The thylakoids contains chlorophyll which captures light for photosynthesis.
This is some extra facts that Ms Sing told us.
EXTRA: The stacks of sacs are connected by stromal lamellae. The lamellae act like the skeleton of the chloroplast, keeping all of the sacs a safe distance from each other and maximizing the efficiency of the organelle.
Okay, gotta go! There is more to come though!
