The correct answer is B. Roots are underground and are not exposed to sunlight.
Chloroplasts are the organelles responsible for photosynthesis, which is the process that converts sunlight into energy. Since roots are underground and do not have access to sunlight, it would be inefficient for them to have chloroplasts. Instead, roots primarily function in nutrient absorption from the soil, which is why they have specialized cells such as root hairs and mycorrhizae to enhance nutrient uptake. Therefore, it is not necessary for root cells to have chloroplasts as their main role is nutrient acquisition rather than energy production.
Using your understanding of the function of chloroplasts and specialized cells, inter why plant root cells lack chloroplasts.
A. Root cells have many mitochondria.
B. Roots are underground and are not exposed to sunlight
C. Root cells have two central vacuoles
D. Roots require fewer nutrients
