¿Qué son las plantas?: transpiración

The video explains the process of respiration in humans and plants. Humans inhale air and exhale gases, including water vapor, which is visible on cold mornings. Similarly, plants exhale water vapor through a process called transpiration, which also involves the release of gases like oxygen. The video highlights how a football pitch can lose significant water on a hot day. It also describes the role of stomata, tiny openings in leaves, which regulate water loss by opening and closing.

What can you observe when you exhale on a cold morning?

• The air becomes warmer.

• Nothing changes.

• The air becomes drier.

• Water vapor is visible.

What is the process called when plants release water vapor?

• Respiration

• Photosynthesis

• Transpiration

• Evaporation

Which gases are produced by plants during transpiration?

• Carbon dioxide and nitrogen

• Methane and hydrogen

• Oxygen and water vapor

• Sulfur dioxide and ozone

What is the function of stomata in plant leaves?

• To absorb sunlight

• To release oxygen

• To control water vapor release

• To store nutrients

How do stomata help plants on a hot day?

• By closing to conserve water

• By opening to absorb more sunlight

• By releasing more oxygen

• By storing more carbon dioxide
