Plants and Air Quality Effects

The video discusses how plants can improve air quality, based on a 1989 NASA study. The study showed that common house plants can remove up to 90% of harmful chemicals from the air. Plants absorb these chemicals through their leaves and roots, with some broken down by soil fungi. The video highlights the effectiveness of different plants, noting that larger plants can remove more chemicals. It concludes with suggestions for further learning and plant care resources.

How do plants remove harmful gases from the atmosphere?

• By absorbing them through their leaves

• By releasing them back into the air

• By converting them into oxygen

• By storing them in their roots and cells

What role do fungi in the soil play in the process of air purification by plants?

• They help break down some of the chemicals
