Which is a difference between plant and animal cells?
a) an animal cell can produce energy, because it has mitochondria.
b) a plant cell has a well defined shape, because it has a cell wall.
c) a plant cell can store genetic information, because it has a nucleus.
d) molecules can only pass into an animal cell because it has a cell membrane.

The correct answer is option B

The only difference that lies between the plant and animal cell is the pressence of cell wall which is made up of cellulose.

The pressence of cell wall in plant cell provides the cell its well defined shape.

The plant cell and animal cell has mitochondria, nucleus, cell membrane and the difference lies in the pressence of cell wall and vacuoles.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
