Transportation and Transpiration
in Plant
Ø Objective of the experiment :
To know how to influence the root pressure on the volume and color.
Ø Device and materials for the experiment :
o Device :
a. Beaker
b. Scissor
c. Colored solution
o Materials :
a. Kingkong flower
Ø Work procedure of the experiment :
o Step 1 : Place kingkong flower stem, with its leaves
intact, in a beaker of colored water as in figure.
o Step 2 : Place a second stem of about the same weight,
wit all its leaves removed in another beaker of
colored water.
o Step 3 : After 20 minutes removes both stalks and cut the stems at regular
intervals to see how far the colored water had risen.
intervals to see how far the colored water had risen.
Ø Results of experiment :
Colored water to absorb into the stem and stem volume are to be changed.
Ø Experiment :
First, prepare device and materials to make this experiment. Then, put the colored solution into a beaker. Wash kingkon flower, and then input into the glass. Then wait for 20 minutes, then cut on the under stem and leaves (reserving a maximum of two leaves, so no wilting to steam) using scissors. If the water colored solution was absorbed into the stem, then the experiment is successful.
Ø Conclusion of the experiment :
Water can be absorbed into its stem because there are xylem and phloem transport
network.
network.
o Xylem tissue is a network that has two functions in plants. The first function is to transport water and minerals from the soil into the stem and leaves. The second function is to support the plant xylem itself so that it is not easy to fall or collapse.
o Phloem tissue is a network that plays an important role in the transport process in plants. Phloem transport sugar sucrose and amino acids from the organs of green plants, especially leaves, to other parts of the plant.
o Transpiration process is in addition lead to the withdrawal of water against the force of gravity, can also cool the plants that are constantly in the sun.
