Question

which one of the following statements is correct?
only plants perform photosynthesis within chloroplasts and only animals perform cellular respiration within mitochondria.
plants perform photosynthesis within chloroplasts and perform cellular respiration within mitochondria.
animals perform photosynthesis within chloroplasts and perform cellular respiration within mitochondria.
both plants and animals perform photosynthesis within chloroplasts and cellular respiration within mitochondria.

Explanation:

Photosynthesis occurs in chloroplasts of plants to convert light - energy into chemical energy. Cellular respiration occurs in mitochondria of both plants and animals to release energy from organic compounds. Animals do not perform photosynthesis as they lack chloroplasts.

Answer:

Plants perform photosynthesis within chloroplasts and perform cellular respiration within mitochondria.
