WebThe gametophyte comprises the main plant (the green moss or liverwort), while the diploid sporophyte is much smaller and is attached to the gametophyte.

Gametophyte plants (green), a few with sporophytes emerging from the top of female plants. Polytrichium is a common moss that occurs across all of North America.

"Web- If confused about sporophyte versus gametophyte: - Gametophyte (2n) literally means the gamete-producing plant. Gametophytes are haploid (1n) and produce gametes (1n) by mitosis. Gametes fuse to form a diploid zygote (2n), which develops into a new sporophyte (2n) (with an embryo in land plants) " - Moss with sporophyte

WebMar 27, 2024 · The male sperm is transported to the female for fertilization which leads to starting off the sporophyte stage in the moss. The zygote formed from the development of the fertilization leads to produce an embryo that grows and matures into a sporophyte. It consists of foot and stalk. WebSporophyte. The diploid zygote develops into a diploid sporophyte. A sporophyte consists of a foot, a long stalk called seta, a capsule which is capped by the operculum. The sporophyte remains attached to the gametophyte much like a parasite, dependent for food and water on the gametophyte, and divides by mitosis.

WebThe sporophyte refers to the diploid generation of the moss. It remains attached to the gametophyte (the haploid mother), and is in fact, parasitic upon it. The sporophyte relies on the gametophyte to provide it with food and water, which are passed through transfer cells that lie in the placental layer between the gametophyte and the sporophyte. WebSep 4, 2024 · Liverworts and mosses differ in the morphology of the haploid gametophyte. The gametophyte is the prominent stage of the life cycle of bryophytes.
