Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which two things are produced when a plant breaks down sugar to release energy?
A
carbon dioxide and water
B
oxygen and carbon dioxide
C
carbon dioxide and food
D
oxygen and food
Explanation: 

Detailed explanation-1: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).

Detailed explanation-2: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Detailed explanation-3: -In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.

Detailed explanation-4: -After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

Detailed explanation-5: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
