Interpret the fern life cycle.Meiosis is the process that produces gametes.

Question

BlackTom AI · Accepted Answer

In fern life cycles, meiosis occurs in the sporophyte phase to produce haploid spores, not gametes. 
The diagram shows a red/meiosis arrow from the zygote (2n) through the sporophyte producing spores (n), which then develop into the gametophyte. 
Gametogenesis (the production of gametes) occurs later, within the haploid gametophyte, and is typically accomplished by mitotic division of gametophyte cells rather than by meiosis. 
Therefore, the statement 'Meiosis is the process that produces gametes' is incorrect because meiosis yields spores in this fern life cycle, while mitosis in the gametophyte yields gametes. 
This distinction is essential: meiosis reduces chromosome number to haploid to form spores; mitosis then supports growth and development of the multicellular gametophyte that makes gametes.
