The leaves of most angiosperms are flat and have a large surface. this enables the plant to:
question 2 options:

a) take in water

b) perform photosynthesis

c) perform cellular respiration

d) store food

Option B

Explanation:

Leaves of most of the angiosperm have big and flat leaves. This enables the leaves to have maximum number of stomata in it.

Maximum light will be absorbed by the leaves and photosynthesis will takes place due to maximum absorption of sunlight.

hence, flat huge surfaces will allow maximum 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.
