Foliose lichens are attached to the substratum at one or few places with the help of

Options

A. Branched, multicellular rhizoids
B. Holdfast
C. Rhizines
D. Rhizomorph

Answer

**Step-by-Step Solution:**

1. **Understanding Foliose Lichens**: Foliose lichens are a type of lichen characterized by their flat, leaf-like structure. They are one of the three main types of lichens, the others being crustose and fruticose.

2. **Attachment Mechanism**: The question asks how foliose lichens attach to their substratum. Unlike some other types of lichens that may have a more extensive attachment, foliose lichens are typically attached at one or a few points.

3. **Identifying the Structure**: The specific structure that allows foliose lichens to attach to their substrate is known as a "rhizine." Rhizines are root-like structures that help anchor the lichen to the surface it grows on.

4. **Conclusion**: Therefore, foliose lichens are attached to the substratum at one or few places with the help of rhizines.

**Final Answer**: Foliose lichens are attached to the substratum at one or few places with the help of rhizines.
