FAQs on Fun Video: Chordates Video Lecture - Biology for Class 9
| 1. What are chordates? |  |
Ans. Chordates are a class of animals that possess a notochord, a dorsal nerve cord, gill slits, and a post-anal tail at some point during their development. They include vertebrates (animals with a backbone) and some invertebrate species.
| 2. What is the significance of the notochord in chordates? | |
Ans. The notochord is a flexible, rod-like structure that provides support to the body and acts as a precursor to the backbone in vertebrates. It also plays a crucial role in the development of the nervous system.
| 3. How do chordates respire? | |
Ans. Chordates respire through gill slits or lungs, depending on the species. In aquatic chordates, gill slits allow for the exchange of gases (oxygen and carbon dioxide) with the surrounding water. In terrestrial chordates, such as mammals, lungs are the primary respiratory organs.
| 4. Can you provide examples of chordates? | |
Ans. Yes, some examples of chordates include fish, amphibians, reptiles, birds, and mammals. Fish, such as sharks and salmon, have gills and live in water. Amphibians, like frogs and salamanders, have both gills and lungs and live both in water and on land. Reptiles, birds, and mammals, including turtles, eagles, and humans, respectively, have lungs and live on land.
| 5. How are chordates classified into different subgroups? | |
Ans. Chordates are classified into three subphyla: Urochordata (tunicates or sea squirts), Cephalochordata (lancelets), and Vertebrata (vertebrates). These subgroups are based on characteristics such as the presence of a notochord, the location of gill slits, and the presence of a backbone. Each subgroup exhibits distinct features and adaptations.
