Plants: tropism

Plants: tropism

The plants fulfill a series of processes that allow them to develop effectively. Within this complex branch of processes we have: tropism and tactism. In this opportunity, we will explain what tropism consists of.

So, what is tropism?

This is a biological process related to external factors that mark the direction of plant growth. This in search of the nutrients necessary for its development. This movement can be positive or negative as it moves away from or approaches the stimulus.

Types of tropism:

The most important tropisms we have geotropism, phototropism, hydrotropism, chemotropism and thermotropism. Next, I will proceed to explain briefly what each one consists of.

Geotropism: in this type of tropism the roots move according to gravity. This will allow the roots the necessary nutrients for it. However, unlike the roots the stem rises above the ground and can be called a negative geotropism.

Phototropism: this movement of the plant is by light. If the stem does not receive enough light, it moves in search of light. This is called positive phototropism.

source

Hydrotropism: the roots of plants move to look for moisture.

Quimiotropismo: the plants will move away or approach those substances that can affect their development. This happens when the stimulus is due to some chemical substance.

Thermotropism: the plant tends to seek heat or avoid it.

Tigmotropism: this takes place when the plant grows on some wall or stone. The plant seeks to adapt to the environment and grows on it.
