What is true about
the life cycle of a land plant?
1. The gametophyte produces spores by meiosis.
2. The life cycle is entirely haploid, so the sporophyte phase does
not exist.
3. The sporophyte produces spores by mitosis.
4. The sporophyte produces spores by meiosis.
5. The gametophyte produces gametes by meiosis.
Homework Answers
The true statement about the life cycle of a land plant is that the sporophyte produces haploid spores by the process of meiosis.
These haploid spored upon germination give rise to the gametophyte which then produces gametes via mitosis.
Hence option D is correct
