Question

in alternation of generations, what is the diploid stage of a plant that follows fertilization called?
○ spore
○ sporophyte
○ gametophyte
○ karyotype
○ chiasmata

Explanation:

In alternation of generations in plants, after fertilization (where two haploid gametes fuse to form a diploid zygote), the diploid stage that develops from the zygote is called the sporophyte. A spore is a haploid reproductive cell. The gametophyte is the haploid stage that produces gametes. A karyotype is a representation of an organism's chromosomes, and chiasmata are structures formed during meiosis. So the correct term for the diploid stage after fertilization is sporophyte.

Answer:

B. sporophyte
