What is the diploid generation called in plants?

• A. Gametophyte
• B. Zygote
• C. Sporophyte
• D. Spore

Answer: (C)

In plant life cycles with alternation of generations, the diploid multicellular phase is called the sporophyte. It starts from a zygote formed by fertilization and grows into the sporophyte, which then produces haploid spores through meiosis. Those spores give rise to the next generation, the gametophyte, which is haploid. A zygote is just a single diploid cell, not the whole diploid generation, and a spore is a haploid reproductive unit, not the diploid stage itself. So the diploid generation is the sporophyte.
