Yesterday, I was experimenting with students at school using white mustard leaves.
This experiments shows that there are transport system contained in plants. How to do is to soak the leave of White mustard into Water dye. Than wait 10-15 minutes, then we can see the mustard lives are the changing color like the color of the soaking water that has been given the dye earlier.
This plants transport means xylem, serves to transport water from the roots to the plant body.
Amazing...! :)
