Read the conditions carefully and write the answers to the questions:
Conditions: A green plant is found growing in the hills of the western Himalayas which shows the following characteristics:
(i) The nuclei of the main plant body have haploid chromosome numbers.
(ii) The main plant body possesses rhizoids.
(iii) The zygote develops into a new plant body which is dependent on the main plant body. This new plant body is a sporophyte.
(iv) The sporophyte has foot, seta, and capsule.
(a) Based on these information, identify the plant from the following options:

Options

A. The plant is an alga.
B. The plant is a bryophyte.
C. The plant is a pteridophyte.
D. The plant is a gymnosperm.

Answer

To solve the question, we will analyze the given conditions step by step and identify the plant based on the characteristics provided.

### Step-by-Step Solution:

1. **Understanding the Characteristics**:
- The plant has a **haploid chromosome number** in the main body.
- It possesses **rhizoids**, which are root-like structures.
- The **zygote** develops into a new plant body that is a **sporophyte**, indicating a life cycle involving alternation of generations.
- The sporophyte has structures called **foot, seta, and capsule**.

2. **Identifying the Plant Group**:
- The presence of a **haploid main plant body** suggests that the plant is a type of non-vascular plant.
- The presence of **rhizoids** indicates that the plant is likely to be a bryophyte, as these structures help anchor the plant and absorb moisture.
- The fact that the **sporophyte is dependent on the gametophyte** is a key characteristic of bryophytes, where the gametophyte is the dominant stage of the life cycle.

3. **Analyzing the Sporophyte Structure**:
- The sporophyte having a **foot, seta, and capsule** is typical of bryophytes, particularly mosses. The foot anchors the sporophyte to the gametophyte, the seta is a stalk that supports the capsule, and the capsule contains spores.

4. **Conclusion**:
- Based on all the characteristics provided, the plant can be identified as a **bryophyte**. Bryophytes are commonly found in moist and shaded areas, such as the hills of the western Himalayas.

### Final Answer:
The plant is a **bryophyte**.
