sporophyte
Solution
The answer is the first one: zygote.
Explanation for each option:
Zygote: This is the correct answer. The zygote is the first stage of the diploid generation in the life cycle of plants and many other organisms. It is formed when two haploid gametes (sperm and egg) fuse during fertilization, resulting in a diploid cell.
Gametophyte: This is incorrect. The gametophyte is part of the haploid generation, not the diploid generation. It produces gametes (sperm and eggs) through mitosis.
Gamete: This is incorrect. Gametes are haploid cells (sperm and egg) that fuse to form a zygote. They are not part of the diploid generation.
Sporophyte: This is incorrect as the first stage. The sporophyte is the multicellular diploid stage that develops from the zygote. It is not the first stage but rather a later stage in the diploid generation.
In summary, the zygote is the initial stage of the diploid generation, formed immediately after fertilization.
