The Sporophytes in Nephrolepis is....... and the spores are

Options

A. Diploid, haploid
B. Haploid, haploid
C. Haploid, diploid
D. Diploid, diploid

Answer

To answer the question about the sporophytes in Nephrolepis and the nature of the spores, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understand the Concept of Sporophyte**:
- The sporophyte is the diploid stage in the life cycle of plants, which arises from the fusion of male and female gametes. This means that the sporophyte has two sets of chromosomes (2N).

2. **Identify the Nature of Sporophytes in Nephrolepis**:
- In the case of Nephrolepis, which is a genus of ferns, the sporophyte is indeed diploid. Therefore, we can conclude that the sporophyte in Nephrolepis is diploid (2N).

3. **Understand the Concept of Spores**:
- Spores are reproductive units that are typically haploid (N) and are produced by the sporophyte through a process called meiosis. These spores can develop into gametophytes, which are the haploid stage of the plant life cycle.

4. **Identify the Nature of Spores in Nephrolepis**:
- Since spores are produced by the sporophyte and are formed through meiosis, they are haploid. Therefore, the spores in Nephrolepis are haploid (N).

5. **Summarize the Findings**:
- To summarize, the sporophyte in Nephrolepis is diploid (2N), and the spores produced are haploid (N).

### Final Answer:
- The sporophytes in Nephrolepis are **diploid (2N)**, and the spores are **haploid (N)**.
