In Spirogyra, the dominant phase is the diploid sporophyte.
Explanation:
To understand why option C is false, we need to understand the life cycles of the organisms mentioned in the options.
1. Bryophytes:
Bryophytes, which include mosses, liverworts, and hornworts, have a life cycle with two distinct phases - the haploid gametophyte phase and the diploid sporophyte phase. However, the predominant phase in bryophytes is the haploid gametophyte phase. This is because the gametophyte is the larger, more visible and long-lived phase, while the sporophyte is smaller and dependent on the gametophyte for nutrition.
2. Volvox:
Volvox is a type of green algae that exhibits a unique form of colonial organization. The main phase in Volvox is indeed the haploid gametophyte phase. The individual cells of Volvox come together to form a hollow sphere called a colony, and each cell within the colony is a haploid gamete-producing organism.
3. Spirogyra:
Spirogyra is a filamentous green algae. In the life cycle of Spirogyra, the dominant phase is the haploid gametophyte phase. The filamentous green algae consist of long, slender filaments of cells, and the individual cells within the filament are haploid and capable of producing gametes.
4. Pappaya:
"Pappaya" is not a known organism, and therefore, we cannot provide information about its life cycle or dominant phase.
Therefore, the false statement is option C, which states that the dominant phase in Spirogyra is the diploid sporophyte. In reality, the dominant phase in Spirogyra is the haploid gametophyte.

"Pappaya" is not a known organism, and therefore, we cannot provide information about its life cycle or dominant phase.
Therefore, the false statement is option C, which states that the dominant phase in Spirogyra is the diploid sporophyte. In reality, the dominant phase in Spirogyra is the haploid gametophyte.

In bryophytes and volvox, the haploid gametophyte phase predominates. Additionally, the haploid gametophyte is the dominant phase in Spirogyra. The haploid gametophyte is the predominant phase in Pappaya.
