What is the difference between plants and animal cells regarding energy storage?

• A. Plant cells store energy as glycogen, while animal cells store energy as starch
• B. Plant cells store energy as glucose, while animal cells store energy as fatty acids
• C. Plant cells store energy as starch, while animal cells store energy as glycogen
• D. Both store energy as proteins

Answer: (C)

Plant cells primarily store energy in the form of starch, which is a polysaccharide made up of glucose units. This storage method is efficient for plants as it allows them to retain energy produced during photosynthesis when they convert sunlight into chemical energy. Starch can then be broken down into glucose when the plant requires energy for growth or metabolism. On the other hand, animal cells store energy as glycogen, which is also a polysaccharide, but it is structurally different and more readily mobilized for quick energy use. Glycogen is stored primarily in the liver and muscle tissues and can be broken down into glucose when the body needs energy rapidly. This distinction is significant because it reflects the different metabolic needs and energy management strategies of plants and animals. While both plants and animals are capable of utilizing glucose for energy, the forms in which they store this energy differ, highlighting their adaptations to their environments and lifestyles.
