Chemistry Air Around Us Part 8 (Plants & Soil need oxygen) Class 6 VI

TL;DR

Plants and soil organisms, such as earthworms, need oxygen to survive and get energy, and they obtain it from the air and soil respectively.

Transcript

hello friends this video on air around us part 8 is brought to you by exam fee or comp no more fear from exam so not only animals and aquatic animals even the plants need oxygen so why do they need oxygen because even plant body is also made up of cells and each of those cells also need oxygen to get energy and if the cells do not work there also t...

Key Insights

• 🌱 Plants and animals, including both aquatic and terrestrial organisms, require oxygen to survive.
• 👱 Plants obtain oxygen through stomata on their leaves, while soil organisms get it from the air within the soil.
• 🥺 Excessive water in the soil during the rainy season leads to a lack of oxygen within the soil, causing earthworms and other organisms to come to the surface to breathe.
• 💦 The presence of bubbles when adding water to dry soil indicates the presence of oxygen in the soil.

Questions & Answers

Q: Why do plants need oxygen?

Plants need oxygen because their cells require it to produce energy. Without oxygen, the cells cannot function, and the plant will not survive.

Q: How do plants obtain oxygen?

Plants obtain oxygen through tiny structures called stomata, which are located on their leaves. These stomata allow for the exchange of gases, enabling the plant to take in oxygen from the air.

Q: Do soil organisms need oxygen?

Yes, soil organisms, including earthworms and other tiny insects, also need oxygen. They obtain oxygen from the air present in the soil, allowing them to breathe and survive.

Q: Why are earthworms more visible during the rainy season?

Earthworms come out on the soil surface during the rainy season because excessive water in the soil blocks air spaces. Since they require oxygen to survive, they come out to breathe in the air present in the surroundings.

Summary & Key Takeaways

• Plants and aquatic animals need oxygen because their bodies are made up of cells that require oxygen to produce energy.

• Plants take in oxygen from the air through tiny pores called stomata on their leaves.

• Soil organisms, including earthworms, obtain oxygen from the soil, which contains air.
