02.03 MCJSC 912 L 143 Which of the following best compares the structures found in plant cells and animal cells? A Animal cells contain cell walls and a large central vacuole while plant cells contain cell membranes and many small vacuoles.

B. Animal cells de not contain chloroplasts, cell walls, or a large central vacuole while plant cells.

C. Plant cells contain rough endoplasmic reticulum and a Golgi apparatus while animal cells contain smooth endoplasmic reticulum surrounded by lysosomes.

D. Plant cells have rigid cell walls and do not contain mitochondria or ribosomes while animal cells do.

one centimetre is equal to 0.01 metres

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
