FAQs on Kingdom Fungi Video Lecture - Biology Class 11 - NEET
| 1. What are the main characteristics of kingdom Fungi? |  |
Ans. Kingdom Fungi is characterized by organisms that are eukaryotic, multicellular (except for yeasts), and heterotrophic. They obtain nutrients by absorbing organic material from their environment. Fungi have cell walls made of chitin, and their body structure is composed of thread-like structures called hyphae.
| 2. How do fungi reproduce? | |
Ans. Fungi can reproduce both sexually and asexually. In sexual reproduction, fungi produce spores that can fuse with other spores of the opposite mating type to form a zygote. This zygote then develops into a new organism. In asexual reproduction, fungi produce spores through mitosis, which can directly grow into new individuals without the need for fusion.
| 3. What is the ecological importance of kingdom Fungi? | |
Ans. Kingdom Fungi plays a crucial role in various ecosystems. They are important decomposers, breaking down dead organic matter and recycling nutrients back into the environment. Fungi also form mutualistic relationships with other organisms, such as mycorrhizal fungi that help plants absorb nutrients from the soil. Additionally, fungi are involved in nutrient cycling, plant diseases, and the production of antibiotics, food, and beverages.
| 4. Can fungi be harmful to humans? | |
Ans. Yes, some fungi can be harmful to humans. Certain species of fungi can cause infections in humans, such as athlete's foot, ringworm, and fungal nail infections. Inhaled fungal spores can also cause respiratory diseases, especially in individuals with weakened immune systems. Additionally, some fungi produce toxins called mycotoxins, which can contaminate food and cause illnesses when ingested.
| 5. How do fungi obtain their nutrients? | |
Ans. Fungi obtain their nutrients by absorbing organic material from their environment. They secrete enzymes that break down complex organic compounds into simpler forms, which can then be absorbed through their cell walls. This unique mode of nutrition allows fungi to decompose dead organic matter, recycle nutrients, and play a vital role in nutrient cycling in ecosystems.
