A leafy gametophyte plant with multicellular rhizoids and sporophyte diffferentiated in foot, seta and capsule should belong to :-

Options

A. Psilopsida
B. Hepaticopsida
C. Bryopsida
D. Lycopsida

Answer

To determine which group the described plant belongs to, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Key Features**: The question describes a plant with a leafy gametophyte, multicellular rhizoids, and a sporophyte differentiated into foot, seta, and capsule.

2. **Understand Gametophyte and Sporophyte**: In plants, the gametophyte is the haploid phase that produces gametes, while the sporophyte is the diploid phase that produces spores. In bryophytes, the main plant body is the gametophyte.

3. **Recognize the Structure of Bryophytes**: Bryophytes, which include mosses, liverworts, and hornworts, typically have a leafy structure (the gametophyte) and their sporophyte is attached to the gametophyte and consists of a foot (for attachment), seta (a stalk), and a capsule (which produces spores).

4. **Examine the Rhizoids**: The presence of multicellular rhizoids indicates that the plant is not a true vascular plant (like ferns or flowering plants) but rather a non-vascular plant, which is characteristic of bryophytes.

5. **Eliminate Incorrect Options**: The options provided include xylopsida, hepatopsida, and lycopsida. Xylopsida and lycopsida are classes of pteridophytes (ferns), while hepatopsida refers to liverworts, which are also bryophytes. However, the correct classification for the described features aligns with bryopsida (mosses).

6. **Conclusion**: Based on the characteristics mentioned, the plant belongs to the group of bryophytes, specifically classified under bryopsida.

### Final Answer:
The plant should belong to **Bryopsida** (option 3).
