**Question: Which of the following apply to the function of vegetative hyphae?**- ○ are necessary in asexual reproduction- ○ are necessary for nutrient acquisition- ● are necessary to provide environmental resistance- ○ none of the above- ○ define a metabolically inactive form of the species- ○ are necessary to support the development of conidia- ○ define the entire mold colony**Explanation:**This question explores the function of vegetative hyphae within fungal organisms. The correct choice is highlighted with a filled circle:- **Vegetative hyphae** are essential for providing environmental resistance. They play a crucial role in maintaining the structure and viability of fungi in various conditions, allowing them to adapt and survive in their environments.Understanding the roles of different types of hyphae is vital for comprehending fungal biology and their interactions within ecosystems. **Quiz Question:**Which of the following words apply to the overlay that maintains proximity between virus and bacteria? This overlay immobilizes the bacteria, but allows for the diffusion of the virus to neighboring cells.- ○ Top Agar- ● Adsorption- ○ Bottom Agar- ○ Lawn- ○ Synthesis**Explanation:**The question asks for a term related to a biological overlay that facilitates interaction between viruses and bacteria. It highlights the function of immobilizing bacteria while enabling viral spread to adjacent cells. The correct answer, marked with a filled circle, is "Adsorption."

Fungi It is wast kingdom eukaryotic organisms. It contains both unicellular as well as multicellular organism. Ans. are necessary for nutrients aquisition The vegitative hyphae links hyphae with the mycelium network. The main function of the vegetative hyphae is to absorb nutrients from the environment and transport it to other part of the body. Other incorrect options Option 1 Aerial hyphae do the asexual reproduction. Option 3 There main defence system is chemical defence. Option 4 It is a active form Option 5 It is not required for development of conidia Option 6 Mycelium represent the whole colony. Ans. Top agar In top agar the concentration of agar is lower and provide movement of phase to infect the bacterial cell. Other incorrect options Adsorption It is dependent upon the composition of cell wall of bacteria and virus. Both are able to do adsorption. Bottom agar In bottom agar is used for streaking single colony of bacteria. Lawn It is used to check sensitivity of bacteria toward different kind of antimicrobial substance. Synthesis This option is also incorrect.
