FAQs on Subphylum - Vertebrata Video Lecture - Biology Class 11 - NEET
| 1. What are the main characteristics of the sub-phylum Vertebrata? |  |
Ans. The sub-phylum Vertebrata is characterized by the presence of a backbone or spinal column, which is made up of individual bones called vertebrae. Vertebrates also have a well-developed internal skeleton, a closed circulatory system, a bilateral symmetry, and a well-differentiated head with a distinct brain.
| 2. How do vertebrates differ from other animals? | |
Ans. Vertebrates differ from other animals in several ways. One key difference is the presence of a backbone or vertebral column, which provides structural support and protects the spinal cord. Vertebrates also have a more complex nervous system, including a well-developed brain. Additionally, vertebrates generally have a higher level of mobility and adaptability compared to other animals.
| 3. What are some examples of vertebrates? | |
Ans. Vertebrates include a wide variety of animals such as mammals (e.g., humans, dogs, and whales), birds (e.g., eagles, pigeons, and ostriches), reptiles (e.g., snakes, turtles, and crocodiles), amphibians (e.g., frogs, salamanders, and newts), and fishes (e.g., sharks, salmon, and goldfish). These are just a few examples of the diverse range of vertebrates found in different habitats worldwide.
| 4. How do vertebrates reproduce? | |
Ans. Vertebrates reproduce in different ways depending on the specific group. Most vertebrates have separate sexes, with males and females coming together for sexual reproduction. Fertilization can be either internal or external, with internal fertilization being more common among land-dwelling vertebrates. Some vertebrates, such as mammals, give birth to live young, while others, such as birds and reptiles, lay eggs.
| 5. What is the importance of vertebrates in ecosystems? | |
Ans. Vertebrates play crucial roles in ecosystems as they occupy various ecological niches and contribute to the overall balance of nature. They serve as predators, prey, and scavengers, helping to regulate populations of other organisms. Vertebrates also participate in nutrient cycling, pollination, seed dispersal, and maintaining biodiversity. Additionally, many vertebrates, such as domesticated animals, provide important resources for human consumption and livelihoods.
