Chloroplast

Definition

noun

Chlorophyll-containing plastid found within the cells of plants and other photosynthetic eukaryotes.


Supplement

Within this organelle are disk-shaped structures called thylakoids that function as the site of photosynthesis. It is because embedded in the thylakoid membrane is the antenna complex consisting of proteins, and light-absorbing pigments, including chlorophyll (the green pigment) and carotenoids. The chlorophyll is capable of absorbing light energy for use in photosynthesis. The high amounts of chlorophyll give chloroplast a green color, making it easily recognizable from the other plastids.


Word origin: Greek words chloros which means green and plast which means form or entity.

Synonym: chloroplastid.
Compare: chromoplast, leucoplast.
See also: chlorophyll.

Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

Because ATP has the responsibility to do so and it may because of evolution. you can refer mitochondria and chloroplast for details how ATP is utilized for energy production.
