Liana : Do you know why most leaves are green?
Cindy : I don’t know. How about you?
Liana : I also don’t know. How if we ask our biology teacher?
Cindy : Good idea. Let’s go now. Hope he has a free time.
Cindy : Good morning Mrs Astuti. How are you today?
Mrs Astuti : Good morning, girls. I’m just fine. How about you?
Liana : We are also fine. Are you busy at the moment?
Mrs Astuti : Not so. Is there anything I can help?
Cindy : We have one question. Why are most leaves green?
Mrs Astuti : Most leaves are green, because they contain chlorophyll.
Liana : What is chlorophyll, teacher?
Mrs Astuti : Chlorophyll (also chlorophyl) is a green pigment found in almost all plants, algae, and cyanobacteria. Do you know what the function of the chlorophyll is?
Liana : Sorry, we don’t know.
Mrs Astuti : It is doing the photosynthesis, which is processing the light into energy.
Cindy : Thank you, teacher.
Mrs Astuti : You’re welcome.
