1. The Journey of a Drop of Water
Through a Plant
By: Ta la M a ll i 8C

2. Introduction
Water is one of the most important elements to keep humans
and animals alive. However, there is one more specie that can’t
live without it. It is the plant. Having said that, the water has a
process of how it travels up the plant, feeds it, and gives it the
nutrition it needs to survive.

3. Water’s Journey through a
Plant
Step 1: The water first enters the ground from the rain, and it is absorbed
in the direction of the Root hairs. Because they are so fine, they can be
easily absorbed through a process called Osmosis.
Osmosis describes how an area of high concentration of water, can
transfer to an area of low concentration.
After that, the water drop starts its journey. After entering the root hairs,
and the roots, the water continues its way up the plant through a process
called cohesion.

4. Water’s Journey through a
Plant
Step 2
Cohesion is when the water drops stick together and travel up
the plant through the Xylem tube.
Then, the water passes through to the Chloroplasts, and then
the Spongy Cells, and then the Wax Cuticle feeding each one.
Because of the effects, of the humidity, heat, or strong winds,
the water escapes through the stomata in the leaf. This is called
Transpiration. The Stomata lets the water out, and the Carbon
Dioxide in.
This causes the water to evaporate into the atmosphere, fall
into the ground and pull up more water up the roots and the
stem. This is a process called Respiration.

5. Photosynthesis
Respiration takes place all the time, but Photosynthesis only happens
during the day.
Photosynthesis is the process which allows the plant to make its own food.
In the leaf, water combines with the Carbon Dioxide in the Chloroplasts,
and the energy stored from the light to make Glucose.
Photosynthesis equation: Carbon Dioxide + Water (+ light energy) -->
glucose + Oxygen or
6 CO2 + 6 H2O --> C6H12O6 + 6 O2

6. After Photosynthesis
After, Photosynthesis takes place, the plant possesses energy in the form
of Glucose; but it also has extra water and oxygen.
These can be kept inside the plant to move the Glucose around through
the Xylem and Phloem tubes.
As the water exits the plant from the leaves, new water is absorbed up the
stem and into the leaves for Photosynthesis again.

7. Benefits of Water in a
Plant
Plants need minerals to help them grow. So the water allows the plant to
take the minerals from the soil.
Water gives the plant and its leaves rigidity and shape. So if the plant is
lacking water, the leaves begin to wither.
