Solution

A zygote in mosses divides by mitosis and develops into a sporophyte.

Here are the steps:

  1. Fertilization: In mosses, fertilization occurs when a sperm fertilizes an egg to form a zygote. This process usually happens in the presence of water.

  2. Formation of Zygote: The fertilized egg, now called a zygote, is diploid, meaning it has two sets of chromosomes.

  3. Mitosis: The zygote then begins to divide by mitosis, a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

  4. Development into Sporophyte: The zygote develops into a sporophyte, which is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the fertilized zygote.

  5. Spore Formation: The sporophyte produces spores by meiosis, a process which reduces the number of chromosomes in each spore to a single set (haploid).

  6. Germination: These spores can then germinate and grow into a new moss plant, starting the cycle again.
