Since no specific question was asked and all options (ExplainAnswer, TeachTopic, GeneratePractice) are set to false, I will provide a clear summary of the fern life cycle as shown in the diagram — which is likely what the student needs for homework.
The fern life cycle has two main stages: the sporophyte (the big leafy plant you recognize as a fern) and the gametophyte (a tiny heart-shaped plant that makes sex cells).
Here’s how it works step by step:
1. The mature fern (sporophyte) has clusters called sori on the underside of its leaves.
2. Inside each sorus are sporangia, which make spores through meiosis.
3. Spores are released into the air (spore dispersal).
4. When a spore lands in a moist place, it grows into a young gametophyte.
5. The gametophyte matures and grows rhizoids (root-like threads) to anchor itself.
6. On the mature gametophyte, antheridia make sperm and archegonia make eggs.
7. Sperm swim through water to reach the egg → fertilization happens.
8. The fertilized egg becomes a zygote.
9. The zygote grows into a young sporophyte while still attached to the gametophyte.
10. Eventually, the young sporophyte becomes independent and grows into a mature fern with fiddleheads unfurling into fronds.
11. The cycle repeats when the mature fern produces new spores.
This is called “alternation of generations” because the plant switches between making spores (sporophyte stage) and making sex cells (gametophyte stage).
Final Answer:
The fern life cycle alternates between a large sporophyte stage (which produces spores via meiosis) and a small gametophyte stage (which produces sperm and eggs for fertilization). Spores grow into gametophytes; after fertilization, the zygote develops into a new sporophyte, completing the cycle.
