FAQs on Water Contains Air: Aquatic Plants and Animals Activity Video Lecture - Science Class 6

1. What are aquatic plants?
Ans. Aquatic plants are plants that grow in water or in soil that is permanently saturated with water. They have adapted to live and thrive in aquatic environments, such as lakes, rivers, and ponds.
2. What are aquatic animals?
Ans. Aquatic animals are animals that live and depend on water for their survival. They can be found in various aquatic habitats, including oceans, rivers, lakes, and wetlands. Examples of aquatic animals include fish, turtles, dolphins, and seals.
3. How do aquatic plants obtain air?
Ans. Aquatic plants obtain air through tiny pores called stomata that are present on their leaves and stems. These stomata allow the exchange of gases, such as oxygen and carbon dioxide, between the plant and its environment. Some aquatic plants also have specialized structures, such as air sacs or aerenchyma, which help them store and transport air.
4. How do aquatic animals breathe underwater?
Ans. Aquatic animals have various adaptations that allow them to breathe underwater. Fish, for example, have gills that extract oxygen from the water. They take in water through their mouths and force it over their gills, where oxygen is absorbed into their bloodstream. Other aquatic animals, such as turtles and dolphins, have lungs and need to come to the water's surface to breathe air.
5. Why is air important for aquatic plants and animals?
Ans. Air is important for aquatic plants and animals because it contains oxygen, which is essential for their survival. Aquatic plants need oxygen for respiration, just like land plants. Aquatic animals, on the other hand, rely on dissolved oxygen in the water to breathe. Without air, both plants and animals would not be able to survive in aquatic environments.
