A lot of “little information is a dangerous thing” here. I know that all* eukaryotes have mitochondrion in their cells. Mitochondrion use aerobic respiration to create ATP. So what are plants using these processes for.

Plus how did they evolve in an oxygen poor early Earth?

Obviously I could be totally wrong on my above assumptions e.g. they need oxygen to produce ATP etc

Edit: Thanks for all the answers even though this post is at 0 votes.
