Quick Answer: Does moss go through mitosis?

Does moss go through a life cycle?

The life cycle of a moss, like all plants, is characterized by an alternation of generations. A diploid generation, called the sporophyte, follows a haploid generation, called the gametophyte, which is in turn followed by the next sporophyte generation.

Does moss undergo mitosis or meiosis?

Life cycle of a moss (genus Polytrichum). The sporophyte generation is dependent on the photosynthetic gametophyte for nutrition. Cells within the sporangium of the sporophyte undergo meiosis to produce male and female spores, respectively.

Does meiosis occur in moss?

The most conspicuous stage of moss is the gametophyte: A haploid stage. … The zygote develops as a multicellular sporophyte, but remains dependent on the female gametophyte. Meiosis takes place in a specialized structure on the sporophyte (the sporangium), producing spores (not gametes!).

Does moss do photosynthesis?

Mosses are primitive plants with low photosynthetic activity. However, they are often very resistant to environmental stresses, mainly because of their poikilohydric water economy, and this greatly extends their distribution area compared to vascular plants.

Are spores produced by mitosis or meiosis?

Spores are usually haploid and unicellular and are produced by meiosis in the sporophyte. Once conditions are favorable, the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which will eventually go on to produce gametes.

Where does mitosis occur in the life cycle of a moss?

After fertilization, the archegonium on the gametophyte plant becomes modified into a protective sheath around the young sporophyte. The sporophyte begins to grow by mitosis (diploid cell division) out of the top of the archegonium.

How does Moss transport water?

Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.
