Yes, plants absolutely need air. Just like animals, they require air for two crucial processes: photosynthesis and respiration.
Photosynthesis: Making Food with Air
Plants use air, specifically carbon dioxide (CO2), during photosynthesis. This process converts light energy, water, and CO2 into sugars (food) for the plant and releases oxygen as a byproduct. Think of it as the plant's way of making its own food using sunlight and the air around it. Without CO2 from the air, photosynthesis wouldn't happen, and the plant would starve.
Respiration: Using Oxygen from the Air
Plants also need oxygen from the air for respiration. This is the process where plants break down sugars (the food created during photosynthesis) to release energy for growth and other life processes. This is similar to how animals breathe – we take in oxygen and release carbon dioxide. Plants do this in reverse during photosynthesis but also require oxygen for respiration.

Practical Example: A plant kept in an air-tight container will eventually die because it runs out of CO2 for photosynthesis and oxygen for respiration.

Key Insight: The availability of air significantly impacts plant health and growth. Providing sufficient air circulation is essential for keeping indoor plants thriving.
The relationship between air and indoor plants is crucial. Sufficient airflow allows for the proper exchange of carbon dioxide and oxygen, essential for both photosynthesis and respiration. Restricting air access negatively impacts plant health.
