Can Plants Move?
Introduction
Plants don’t move around like animals, but they can definitely move! They move to grow, catch sunlight, and even feed themselves. One of the most common ways plants move is called phototropism. They move and grow towards the light. You’ve probably seen this with a houseplant that you rotate to make it grow evenly. It will grow more towards the sunny side.
How Do Plants Move?
Plants can move in response to different things, not just light. They can move or grow in response to touch, chemicals, or warmth. Some plants even close their flowers at night when there’s no chance of a pollinator visiting.
Types of Plant Movement
1. Phototropism: Plants move towards the light. This helps them get the energy they need to grow.
2. Thigmotropism: Plants move in response to touch. Some plants, like the sensitive plant, will close their leaves when you touch them.
3. Hydrotropism: Plants move towards water. This helps them get the moisture they need to survive.
4. Chemotropism: Plants move in response to chemicals. Some plants, like the Venus flytrap, use chemicals to attract and trap insects.
5. Nyctinasty: Some plants close their leaves or flowers at night. This helps them protect themselves from the cold or from predators.
Notable Plants That Move
Some plants move more dramatically than others. Here are a few examples:
- Venus flytrap: This carnivorous plant traps insects in its “jaws.”
- Bladderwort: This aquatic plant traps prey in a similar way to the Venus flytrap.
- Sensitive plant: This plant’s leaves close up quickly when you touch them.
- Prayer plant: This plant folds up its leaves at night, as if in prayer.
- Telegraph plant: This plant’s leaves move at a moderate speed.
- Trigger plant: When a pollinator visits this plant’s flower, it triggers the reproductive organs to snap forward, covering the insect in pollen.
How Fast Do Plants Move?
The speed of plant movement varies depending on the species. Some plants, like the Venus flytrap, can move very quickly. Others, like the prayer plant, move more slowly.
Why Do Plants Move?
Plants move for a variety of reasons, including:
- To get sunlight
- To get water
- To attract pollinators
- To protect themselves
Conclusion
Plants are fascinating creatures that have evolved to move in a variety of ways. These movements help them to survive and thrive in their environment.
