10 Questions
What are the two life stages that mosses go through?
The two life stages that mosses go through are haploid and diploid.
What are the reproductive organs of mature female moss plants called?
The reproductive organs of mature female moss plants are called archegonia.
What is the alternation of generations?
The alternation of generations is the change between haploid and diploid life stages in mosses.
What are the two stages in the life cycle of moss?
The two stages in the life cycle of moss are haploid and diploid.
What is the purpose of the antheridium in moss?
The antheridium in moss produces sperm.
What is the alternation of generations in moss?
The alternation of generations in moss refers to the switch between the haploid gametophyte phase (n) and the diploid sporophyte phase (2n).
What is the dominant life stage in the overall cycle of mosses?
The gametophyte stage is the dominant life stage in the overall cycle of mosses.
What are the two different types of gametophytes in moss?
The two different types of gametophytes in moss are the female and the male.
What are the male reproductive organs in moss called?
The male reproductive organs in moss are called antheridia.
What is the process called where the zygote splits into two identical cells?
The process where the zygote splits into two identical cells is called mitosis.
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.
