10940478038NucleusControls the cells activities and contains the DNA.0
10940478039VacuoleLarge balloon-like structures that hold water, food and waste that the cell doesn't need right away.1
10940478040ChloroplastAn organelle found in plant cells where photosynthesis occurs. It has folded structures that absorb sunlight.2
10940478041Cell WallOnly present in plant cells. It is much less flexible than the cell membrane and it gives the cell shape.3
