maw [93]

Plants absorb water from the ground. In the experiment, we can see that cabbage leaves take water from the glasses through the process of transpiration. Together with water the leaves absorb the pigments.

<h3 />

Experiment      

1) Four glasses of water, each with a different color ⇒ red, blue, yellow, orange

2) One or two cabbage leaves are placed in each glass and left there for eight hours.

3) After 8 hours, the leafs turn into the color of the colored-water in which they are placed.

<h3>Explanation</h3>

When placing cabbage leaves in the glasses, they start to absorb water from the stems.

As they absorb water to drive it to other parts of the leaf, they also absorb the pigments that are giving color to the water.

As time passes by, the leaves acquire the same color as the water.

<h3>Water absorption: Transpiration</h3>

Plants absorb water from the ground. This process is known as transpiration.

Roots are the first organ that gets in touch with water.

The xylem in roots and stems is in charge of this process.

The xylem composes the vascular system that transports water and minerals through its vessels and tracheids from the roots to the aerial parts of the plants.

Water can move from the ground to the aerial parts of the plant thanks to osmosis and hydric gradient potential.
