If we were to compare the cells in the plant leaves to the cells in the plant roots, we would expect the leaf cells to contain many more a) chloroplasts. b) leucoplasts. c) nuclei. d) ribosomes.

A)chloroplasts.

Explanation:

We would expect the leaf cells to contain many more chloroplasts. The leaf is the main site of photosynthesis. Chloroplasts contain chlorophyll, a pigment used to collect sunlight which is converted to glucose during photosynthesis.

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.
