Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is photosynthesis important to plants?
A
It prevents the buildup of too much water in their cells.
B
It produces the carbon dioxide they need for plant digestion.
C
It breaks down a simple sugar into a type of energy their cells can use.
D
It produces a simple sugar they need for cellular respiration.
Explanation: 

Detailed explanation-1: -The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

Detailed explanation-2: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

Detailed explanation-3: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Detailed explanation-4: -During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
