The sporophyte or sporogonium is partially (funaria ) or fully dependent upon the gametophytic generation. Hence the option 'C' is correct.

Sporophyte and Gametophyte in Funaria:

Funaria is a genus of Mosses that belongs to the division Bryophyta. It is a non-vascular plant, meaning it lacks true roots, stems, and leaves. Funaria has a life cycle that alternates between a haploid gametophyte and a diploid sporophyte generation.

Sporophyte and Gametophyte in Funaria are two different generations of the plant, and they have distinct characteristics. Let us understand the difference between the two:

Gametophyte:

- Gametophyte is the haploid, gamete-producing stage in the life cycle of Funaria.
- It is the dominant stage in the life cycle of Funaria.
- The gametophyte is a small, green, leafy structure that lives on the soil surface.
- It is independent and photosynthetic.
- It develops from a haploid spore, which germinates and grows into a multicellular structure.
- The gametophyte produces gametes (sperm and egg cells) in specialized organs called gametangia.
- The gametes fuse to form a diploid zygote, which develops into the sporophyte.

Sporophyte:

- Sporophyte is the diploid, spore-producing stage in the life cycle of Funaria.
- It is a small, brown, stalk-like structure that grows on the gametophyte.
- The sporophyte is partially dependent on the gametophyte for nutrition and support.
- It develops from the zygote, which is produced by the fusion of sperm and egg cells.
- The sporophyte consists of a foot, seta, and capsule.
- The capsule contains spores, which are released into the environment and germinate to produce new gametophytes.

Sporophyte in Funaria is a partial parasite:

- The sporophyte of Funaria is considered a partial parasite because it is partially dependent on the gametophyte for nutrition and support.
- The sporophyte obtains water and nutrients from the gametophyte through a specialized structure called the foot.
- The foot of the sporophyte grows into the gametophyte tissue and absorbs nutrients from it.
- However, the sporophyte is also capable of photosynthesis and produces some of its food.
- Therefore, it is considered a partial parasite, as it relies on the gametophyte for some nutrients, but it can also produce some of its food.

Conclusion:

In Funaria, the sporophyte is a partial parasite that is partially dependent on the gametophyte for nutrition and support. The gametophyte, on the other hand, is independent and photosynthetic. The two generations have distinct characteristics and play different roles in the life cycle of the plant.
