Question:

Coenocytic hyphae are-

Options:

1. Continuous tubes filled with uninucleated cytoplasm
2. Continuous tubes filled with multinucleated cytoplasm
3. Branched tubes filled with multinucleated cytoplasm
4. Branched tubes filled with uninucleated cytoplasm

Solution:

Page 22, XI NCERT. Coenocytic hyphae are continuous tubes filled with multinucleated cytoplasm, without any internal cross-walls or septa. This type of hyphae is commonly found in members of the fungal class Zygomycetes, which includes genera such as Rhizopus and Mucor. The multinucleated cytoplasm of coenocytic hyphae allows for rapid and efficient transport of nutrients and other molecules throughout the fungus.
