Of all land plants, bryophytes alone have independent ….... and attached, dependent ……...

Options

A. sporophytes, gametophytes
B. rhizoids, zygotes
C. gametophytes, sporophytes
D. rhizoids, stalked sporangia

Explanation

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Begin by recognizing that bryophytes are a group of land plants that include mosses, liverworts, and hornworts. They are often referred to as the amphibians of the plant kingdom because they thrive in moist environments and require water for reproduction.

2. **Life Cycle of Bryophytes**: Bryophytes exhibit a life cycle that includes two distinct generations: the gametophyte and the sporophyte. The gametophyte generation is the dominant phase in bryophytes.

3. **Identifying Dominant and Dependent Structures**: In bryophytes, the gametophyte is independent, meaning it can live and grow on its own. In contrast, the sporophyte is dependent on the gametophyte for its nutrition and support, as it remains attached to the gametophyte throughout its life.

4. **Filling in the Blanks**: Based on the understanding of the life cycle and the roles of gametophytes and sporophytes, we can fill in the blanks in the question: "Of all land plants, bryophytes alone have independent **gametophytes** and attached, dependent **sporophytes**."

5. **Conclusion**: The correct answer to the question is that bryophytes have independent gametophytes and attached dependent sporophytes.
