The mitochondria and chloroplasts in eukaryotic cells are descendant from bacteria. Ancient eukaryotic cells ingested these bacteria and they became part of the larger cell structure. Mitochondria and chloroplasts work symbiotically with the cell to provide it with energy. Because these mitochondria and chloroplasts used to be separate bacteria living on their own, they had their own small circular DNA like all bacteria do. When they became part of the eukaryotic cell they retained this DNA. Mitochondria and chloroplasts also reproduce similar to bacteria and replicate their DNA the same way. In this way, all mitochondria and chloroplasts in the organism contain the same circular small genome, just like all nuclei in the organism contain the same spiral DNA.

Explanation:
<span>Vascular plants can be classified into two major types:
gymnosperms or angiosperms</span>
The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)<span />
