The green color is for the chlorophyll.
00:00:07
The chlorophyll is in the leaves.
00:00:21
Chlorophyll has many pigments.
00:00:27
It is a special solar panel.
00:00:33
This energy is used to cook the food for plants.
00:00:37
With this practice, we are going to look for different pigments in the chlorophyll.
00:00:44
We need all these instruments.
00:00:52

00:00:55
Test tubes.
00:01:04

Step 1.
00:01:17
Cut them and pour 10 ml of alcohol.

Step 2. It's time of the purple leaf.
00:01:36
I'm going to do the same process with the purple pigments.
00:02:17
Time is over. Now we put the green leaves and the purple leaves.
00:03:45
The dark green color is the chlorophyll.
00:04:22
The yellow one is another pigment, in the purple leaves we can see the purple pigment.
