There are two major types of carbohydrates (or carbs) in foods: simple and complex. Simple carbohydrates: These are also called simple sugars. They're found in refined sugars, like the white sugar you see in a sugar bowl. If you have a lollipop, you're eating simple carbs. But you'll also find simple sugars in more nutritious foods, such as fruit and milk.
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
Thylakoids are flattened sacs within the chloroplasts. They are stacked together to form structures called grana. Thylakoids are central to photosynthesis because molecules that absorb solar energy, (photosynthetic pigment) are located in the thylakoid membrane. Was this helpful? Let the contributor know!
