Explanation:
A. The nursery industry uses sphagnum moss as a plant development medium. Moss is a good alternative to mulch since it absorbs water, avoids erosion, and waste can simply be blown away due to its compact growth pattern. It's also good for mosquito control because it doesn't get stagnant and instead filters the water.
B. Sporophytes are also diploid, which means they have two sets of chromosomes. In contrast, gametophytes are haploid, meaning they contain only one set of chromosomes. The most significant distinction between sporophyte and gametophyte is this.
