Verified step by step guidance1
Understand the concept of ploidy: Diploid cells contain two sets of chromosomes, one from each parent, while haploid cells contain only one set.
Identify the structures involved in the life cycle of sexual reproducers: Sporophyte, Gamete, Zygote, and Spore.
Analyze the ploidy of each structure: Gametes (sperm and egg) are haploid, containing one set of chromosomes.
Consider the zygote: When two gametes fuse during fertilization, they form a zygote, which is diploid, containing two sets of chromosomes.
Review the role of the sporophyte: In many plants, the sporophyte is also diploid, as it develops from the zygote and undergoes mitosis to grow.
