watch the trachea of the plant

What we will learn

This is an experiment that looks at the trachea which we explained in "the structure and types of the plants".
Dye the trachea with colored water.
In this experiment, we used a sunflower as a representative of Dicotyledones.

Preparations
		・a plant to examine ・container to put a plant in（ a flask ）・ink（favorite color）・microscope ・knife
Procedure
		At first we dissolve ink in water to make the bye. The color of the ink is up to you.
		Cut the root of the plant which we want to examine.
		Soak the plant which cut a root in colored liquid.
		Leave it unattended for two or three hours.
		After time passes, take out the plant from the ink and slice the stem into as much small a piece as possible.
		With a microscope, observe the state of the stem.
Results
		We found that the part which became red is the form of a ring when we cut the stem. In addition, the stem which we cut lengthwise shows that the red part is continuous through the stem.

Conclusion
The part which turned red is colored by the water.The part which turned red in the photograph is the trachea. In addition, the trachea continues throughout the stem.
