Using your understanding of the function of chloroplasts and specialized cells, infer why plant root cells lack chloroplasts.(1 point)
Responses
Root cells have two central vacuoles.
Root cells have two central vacuoles.
Roots require fewer nutrients.
Roots require fewer nutrients.
Roots are underground and are not exposed to sunlight.
Roots are underground and are not exposed to sunlight.
Root cells have many mitochondria.
Root cells lack chloroplasts because they are underground and do not receive sunlight.
The correct answer is: Roots are underground and are not exposed to sunlight.
Chloroplasts are specialized organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. Since roots are primarily located underground, they are not exposed to sunlight and, therefore, do not have a need for chloroplasts. Chloroplasts are typically found in the cells of plant leaves and stems, which are more exposed to sunlight and require energy for photosynthesis. Thus, the absence of chloroplasts in root cells is due to their underground location and lack of sunlight exposure.
