The difference between the plant and animal cells is in their structures, and this makes their functions to differ. Some organelles are present in the plant cell which are absent in the animal cell and vice versa. The presence/absence of these organelles impact the kind of functions that can be carried out by each cell.
- The plant cell has a rigid cell wall made of polysaccharides while the animal cell lacks cell wall. The cell wall serves supportive functions in the plant and gives it a shape. Animal cells are more or less round in shape.
- Plant cells have chloroplasts while it is absent in the animal cell. the chloroplast contains chlorophyll, a green pigment that is responsible to absorbing radiant energy, As such, the chloroplast enables plant cells to carry out photosynthesis. Animals cells cannot synthesize their own foods.
- Plant cells have large central vacuole that stores water and other contents while animal cells have small vacuole
- Animal cells have centrioles while plant cells do not. The centrioles make mitotic division different between the two cells, although, the same result is obtained at the end of the day.

Explanation:
A mole is the amount of matter or substance that contains the Avogadro's number of particles.
1 mole of a substance = 6.02 x 10²³ atoms
Now solving:
a:
1.2 x 10² atoms ;
Number of moles = = 2.0 x 10⁻²¹moles
b:
3.87 x 10²¹ molecule:
Number of moles = = 6.4 x 10⁻³moles
c. 4.81 x 10¹⁴ molecules:
Number of moles = = 8.0 x 10⁻¹⁰moles
Number of molecules = number of atoms = formula units

<span>According to octet rule, atoms with an atomic number less than 20 tend to combine with other atom such that both of these atoms have eight electrons in their valence shells, which gives them the same electronic configuration as that of noble gas.
However, there are few compound that donot obey octel rule. Among the elements mentioned above i.e. oxygen and helium obeys octet rule.
In case of nitrogen, oxide of nitrogen (like NO and NO2) have incomplete octet.
While there are few compounds of Br wherein Br has expanded octet. For example, in BrF5, Br has 12 electrons in valence shell. </span>
The answer is D. Carbon dioxide + Water + Light source = Sugar and oxygen
