FAQs on Fungi Video Lecture - Science & Technology for State PSC Exams - BPSC (Bihar)

1. What are fungi?
Ans. Fungi are a diverse group of organisms that belong to the kingdom Fungi. They are eukaryotic, which means their cells have a nucleus enclosed within a membrane. Fungi can be found in various habitats, including soil, water, and even on other living organisms.
2. How do fungi obtain nutrients?
Ans. Fungi obtain nutrients through a process called absorption. They secrete enzymes that break down organic matter into smaller molecules, which can then be absorbed by the fungal cells. This allows fungi to obtain energy and nutrients from a wide range of organic materials, including decaying organic matter, plants, and even other animals.
3. What is the role of fungi in ecosystems?
Ans. Fungi play several important roles in ecosystems. They are essential decomposers, breaking down dead organic matter and recycling nutrients back into the environment. Fungi also form mutualistic relationships with plants, providing them with nutrients in exchange for sugars. Additionally, some fungi are pathogens, causing diseases in plants, animals, and humans.
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. In addition, exposure to certain types of molds can lead to respiratory problems and allergies. However, it's important to note that the majority of fungi are not harmful to humans and play beneficial roles in ecosystems.
5. Are fungi important in medicine and industry?
Ans. Yes, fungi are important in both medicine and industry. Many antibiotics, such as penicillin, are derived from fungi. Fungi are also used in the production of various food and beverage products, such as bread, cheese, and beer. In addition, certain fungi are used in biotechnology to produce enzymes, biofuels, and other valuable compounds.
