Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The reactants and products for respiration are exactly the same for a plant cell and an animal cell, the difference is the ____ of the reactants.
A
beginning
B
product
C
total
D
source
Explanation: 

Detailed explanation-1: -The difference between this process in plant and animal cells is the SOURCE of the glucose or food molecule that is broken down. Plants get their food from PHOTOSYNTHESIS (autotroph) while animals get theirs by feeding on other organisms (heterotroph).

Detailed explanation-2: -Plants and animals have their different ways of respiration; they respirate through different organs and have different end products. Plants do not breathe, they only respire through their leaves. Animals breathe air for cellular respiration.

Detailed explanation-3: -Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

Detailed explanation-4: -The products and reactants for photosynthesis are reversed in cellular respiration: The reactants of photosynthesis are carbon dioxide and water, which are the products of cellular respiration. The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis.

Detailed explanation-5: -The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.
