DESTARCHING LEAVES!!! OH GOD!!

[icesheikh]

hey everyone, im new here! n i totally hate bio but i have 2 take it .. newayz vr doing sumthin wid leavez .. da question is how can i remove chlorophyll from leavez and y r leavez destarched b4 experimenting? and wat happenz 2 da starch at night?

[icesheikh]

cum on ppl i need help here!!!!

[mith]

it would help if you wrote something that we can understand...like proper english?

how can i remove chlorophyll from leaves and why are leaves destarched before experimenting? and also what happens to the starch in the leaves at night?

[MrMistery]

At night starch is degraded, because there is no photosynthesis going on, but the plant needs to undergo cell respiration.
To remove chlorophil from a plant you simply cut the leaf into little pieces. then you put them in a solvent, preferably CH3-CH2-OH. Boil it until the the leaves have no color and the alcohol is green. Filter the extract after that through a filter paper. Then you got yourself a nice chlorophil extract. You do not need to destarch the leaves for the experiment, i have done it last year.

Another experiment is done by destarching leaves: the influence of light on photosynthesis

[icesheikh]

photosynthesis??

[MrMistery]

yes, photosynthesis...

You experiment is much simpler than mine………….
We did the same experiment using separating funnel this semester but with a little different. We add acetone during grinding of the leaves then we filter the extract. Next step is really complicated, we add to this extract a system of different solvents e.g petroleum ether. There is no boiling. Finally, you will get different colored layers of each pigment.

you guys almost make my brain hurt from this

photosynthesis??

Basically photosynthesis is a process by which plants make energy by converting light energy into chemical energy.

That's because you did a completely different experminent: what you did is separation of different pigments in plants not chlorophil extraction

Really
you drive me crazy .that's was my first post and I really thought I did well.I need some encouragment here
and what about your experiment?did it seperate chlorophyll only?It doesn't seem that.
