The plant body of all bryophytes are gametophyte, haploid and thallus like having -

Options

A. Root + Stem + Leaf
B. No root + no stem + no leaf
C. Xylem and phloem
D. Wood

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. They are characterized by their dominant gametophyte stage in their life cycle.

2. **Gametophyte Structure**: The plant body of bryophytes is primarily a gametophyte, which is haploid. This means that the cells of the gametophyte contain only one set of chromosomes.

3. **Thallus-like Structure**: The body of bryophytes is often thallus-like, meaning it does not have true roots, stems, or leaves as seen in higher plants. Instead, they have structures that perform similar functions but are not classified as true organs.

4. **Absence of True Roots, Stems, and Leaves**: In bryophytes, true roots, stems, and leaves are absent. They may have structures called rhizoids that help anchor them to the substrate but do not function like true roots.

5. **Absence of Vascular Tissue**: Bryophytes lack vascular tissues such as xylem and phloem. This means they do not have specialized structures for the conduction of water and nutrients, which limits their size and habitat to moist environments.

6. **Conclusion**: Given the characteristics of bryophytes, the correct statement about their plant body is that they are gametophyte, haploid, thallus-like, and lack true roots, stems, leaves, xylem, and phloem.

**Final Answer**: The plant body of all bryophytes is gametophyte, haploid, and thallus-like, having no true roots, stems, leaves, xylem, or phloem.
