Yes, chloroplasts are found only in plants (and a few protists), and they're filled with chlorophyll to help them absorb light energy.
No, mitochondria do not have thylakoids. Thylakoids are a membrane system containing chlorophyll found in chloroplasts, while mitochondria have inner and outer membranes but do not contain thylakoids. Mitochondria are involved in cellular respiration, not photosynthesis like chloroplasts.
Granum
The chloroplasts
A stack of thylakoids is called a stroma.
These are thylakoids, which contain chlorophyll and are the sites of photosynthesis in chloroplasts. Thylakoids are arranged in stacks known as grana, where light reactions of photosynthesis occur.
