Tropisms
Imagine placing a potted plant near a window. After a few days, you notice that its stem leans toward the sunlight. Why does this happen?
This movement, called tropism, helps plants find light, water, and support. Depending on the plant's reaction, there are different types of tropisms.
First is phototropism, which occurs when plants grow toward a light source. Leaves and stems bend toward sunlight to get more energy for photosynthesis, while roots grow away from light to reach water underground.
Next is gravitropism, which is a plant’s response to gravity. Roots grow downward, anchoring the plant and absorbing nutrients, while shoots grow upward against gravity.
The last one is thigmotropism, a plant’s reaction to touch. Vines and tendrils wrap around poles or other surfaces for support, helping them climb toward sunlight.
These tropisms allow plants to survive by guiding them in the right direction, ensuring they get the necessary resources!
