Hello llockard,

BUT, in case of petroleum, it takes nearly 100000 years, which is impossible for any human to live that much years... So, use petroleum carefully....

A student is examining leaf cells. Which organelle is most likely to be missing from the cells?
Olegator [25]

The organelle which is most likely to be missing from leaf cells is Lysosomes.

Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls.  Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.
