Introduction
Just like humans and animals, plants also need to breathe to stay alive. But plants do not have noses or lungs. Instead, they use special parts to take in air and release gases. Let’s understand this interesting process in a simple way.
Do Plants Really Breathe?
Yes, plants do breathe, but their breathing is different from humans. Plants do not inhale and exhale through lungs. They exchange gases through tiny openings in their leaves.
What Are Stomata?
Plants breathe through small holes called stomata (singular: stoma). These are found mostly on the leaves.
- Stomata are too small to see with our eyes
- They open and close like tiny doors
- They help in gas exchange
How Do Plants Breathe?
Plants take in air and release air through stomata:
- Plants take in carbon dioxide (CO₂) from the air
- They release oxygen (O₂) into the air
This process mainly happens during the day when sunlight is available.
Role of Leaves in Breathing
Leaves are like the “lungs” of plants. They help in breathing and also in making food through a process called photosynthesis.
Do Plants Breathe at Night?
Yes, but in a different way. At night, plants do not make food, but they still take in oxygen and release carbon dioxide in small amounts.
Why Is Plant Breathing Important?
Plant breathing is important because:
- It helps plants stay alive and healthy
- It keeps the air fresh by releasing oxygen
- It supports life on Earth
