Because cell function is so heavily dependent on effectively transporting materials across the cell membrane, cell size is limited due to the need for a ___________ ratio of surface area to volume.

This theory states that membrane bound organelles evolved from once free-living prokaryotes that were engulfed to compose the eukaryotic cells that we observe today.

Who is the (ATP producing, glycolysis/krebs cycle running) powerhouse of the cell?
