here is a question, since no one has any to ask, lol

What is the role if chlorophyll in green plants? [3]

I think, acts as a catalyst, or its the place where reactions(photosynthesis) takes place. I'm not sure. :D

close, but not fully right
It has the suitable condetions for the reactions to take place?  :-\

no not really, its for 3 marks so u must have 3 point,
Ans: absorbs light energy from the sun[1], and acts as a catalyst[1] in the reaction between carbon dioxide and water[3]
and if u want give the symbolic reaction (its better to give it)

well Bessy i think that potassium is yellow not iodine...
and ioden is purple/black that wat i think...
and +rep if i m correct :)

Group 1 and 2 metals are alkalis and they r all colorless solutions...so potassium not yellow
Iodine...being in the 7th group is a black/grey solid; purple liquid and gas
