Verified step by step guidance

Understand the basic plant life cycle, which alternates between two stages: the haploid gametophyte and the diploid sporophyte.

Recognize that the gametophyte stage is haploid, meaning it contains a single set of chromosomes and produces gametes (sperm and eggs) through mitosis.

Identify that the sporophyte stage is diploid, meaning it contains two sets of chromosomes. This stage arises from the fusion of gametes (fertilization) and produces spores through meiosis.

Recall that spores are haploid cells produced by the sporophyte through meiosis, which will grow into the gametophyte stage.

Conclude that the diploid life cycle stage in plants is the sporophyte, as it is the stage that contains two sets of chromosomes and gives rise to spores.
