how is mitochondria second-largest cell organelle but third-largest cellular component of plant cell?

Dear student
Please find your answer below to the asked query:

If we consider the surface area as the criteria then the smallest cell organelle is ribosome and the largest cell organelle is nucleus in animal cell & vacuole in plant cell. 
In animal cell Mitochondria is second largest cellular organelle, but Chloroplast(Plastids) are much larger than Mitochondria. So in Plants, Chloroplast becomes second largest organelle and third largest organelles of plant cell is thus Mitochondria.
