To begin with, it is clear that this cell has a cell wall (the rigid cubicle like structure around the cell). Only plants (that can carry out photosynthesis) have a cell wall. Secondly, one can view the chloroplasts in the cell (the organelles with green pigments inside). This is where photosynthesis takes place in the cell.
Since homologous means same structure different functions, it shows that animals evolve to have the same structure as their ancestors but, have different uses to the part
