What type of spores are in bryohytes?

Options

A. Triploid in nature
B. Tetraploid in nature
C. Haploid in nature
D. Diploid in nature

Answer

### Step-by-Step Solution:

1. **Understanding Bryophytes**: Bryophytes are non-vascular plants, commonly referred to as mosses and liverworts. They are known for their dependence on water for reproduction.

2. **Life Cycle of Bryophytes**: The life cycle of bryophytes includes two main phases: the gametophyte phase and the sporophyte phase. The gametophyte is the dominant phase and is haploid.

3. **Gametophyte Phase**: In the gametophyte phase, bryophytes produce gametes (sperm and eggs). These gametes are haploid (n), meaning they contain one set of chromosomes.

4. **Fertilization**: When the sperm fertilizes the egg, a diploid zygote (2n) is formed. This zygote then develops into the sporophyte.

5. **Sporophyte Phase**: The sporophyte is dependent on the gametophyte for nutrition and is typically attached to it. The sporophyte is diploid (2n) and undergoes meiosis to produce spores.

6. **Spores**: The spores produced by the sporophyte are haploid (n). This means that they contain one set of chromosomes, which is characteristic of spores in bryophytes.

7. **Conclusion**: Therefore, the type of spores present in bryophytes is haploid.

### Final Answer:
The spores in bryophytes are haploid in nature.
