Explain how the cells of a plant's gametophyte differ from the cells of a plant's
sporophyte

Diploids cells contain two chromosome sets. For plants, haploid and diploid cells divide via mitosis. The plants' haploid phase is called the gametophyte, and the diploid phase is called the sporophyte. Offspring alternate from diploid sporophytes to haploid gametophytes and back again in generations.

hope it helps

explanation:

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
