In pteridophytes, the main plant body is `:`

Options

A. a gametophyte
B. thalloid
C. non vascular
D. a sporophyte

Answer

To answer the question "In pteridophytes, the main plant body is:", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Plant**:
- Pteridophytes are a group of vascular plants that reproduce via spores and do not produce seeds.

2. **Determine the Main Plant Body**:
- In pteridophytes, the main plant body is known as the sporophyte.

3. **Understand the Structure of the Sporophyte**:
- The sporophyte is differentiated into three main parts: roots, leaves, and stems.

4. **Recognize the Vascular Tissue**:
- Pteridophytes possess vascular tissues, which include xylem and phloem, essential for the transport of water, nutrients, and food.

5. **Define the Sporophyte**:
- The sporophyte is a diploid multicellular stage in the life cycle of plants, including pteridophytes. It develops from the zygote formed by the fusion of a haploid egg and a haploid sperm.

6. **Conclude the Answer**:
- Therefore, the main plant body of pteridophytes is the sporophyte.

### Final Answer:
In pteridophytes, the main plant body is the sporophyte.
