Well, when chromosomes cross over during prophase 1 of meiosis, the homologous pair of chromosomes exchange segments of DNA which happen to be the genes. So the significance of crossing-over during prophase 1 is that it adds genetic variation to sexually reproducing organisms.
There would be less oxegen and also economically exploit us as 80% of things we use is from trees. we will be ruined, that's for sure.

Prokaryotes do not have a nucleus, rather the DNA floats freely in the cytoplasm. Also, prokaryotes are much smaller than eukaryotes, and are typically bacteria or eubacteria.
Eukaryotic cells have membrane-bound organelles and nucleus, and are larger than prokaryotes. Some examples of eukaryotes are plant and animal cells. Hope this helps! :)
