Plants and animals need energy in order to live. Which of the following statements about the conversion of food energy into other forms of energy is true?

Question

A.
The process takes place in the chloroplasts of plant and animal cells.
B.
Plant and animal cells require oxygen to properly break down food molecules.
C.
Sunlight is required to break down food in plants and animals.
D.
all of these

Answer 1

The correct answer is B. Plant and animal cells require oxygen to properly break down food molecules.

Here's a brief explanation for each statement:

A. False. The process of converting food energy primarily takes place in mitochondria (in both plant and animal cells) for cellular respiration, while chloroplasts are involved in photosynthesis in plants.

B. True. Both plant and animal cells require oxygen to efficiently metabolize food through cellular respiration.

C. False. Sunlight is not required to break down food in animals; it's primarily needed in plants for photosynthesis to produce food.

D. False. Since A and C are not true, this statement cannot be true either.

Thus, only statement B is correct.
