Study Notes
Life Cycle of Mosses
- Mosses undergo two life stages: gametophyte and sporophyte.
Gametophyte Stage
- The female reproductive organs of mature moss plants are called archegonia.
- The male reproductive organs in moss are called antheridia.
- Antheridia produce non-motile sperm that require water to reach the egg cell.
- The purpose of an antheridium is to produce sperm for fertilization.
Sporophyte Stage
- The sporophyte stage is the stage where spores are produced.
- Spores are similar to the seeds of flowering plants.
Alternation of Generations
- The alternation of generations is a process where mosses alternate between two different life stages: gametophyte and sporophyte.
- The gametophyte stage produces gametes (sperm and egg cells), while the sporophyte stage produces spores.
- The sporophyte stage is dominant in the overall cycle of mosses.
Cell Division
- The process where the zygote splits into two identical cells is called mitosis.
Types of Gametophytes
- There are two different types of gametophytes in moss: male and female.
- The male gametophyte produces antheridia, while the female gametophyte produces archegonia.
