Root cells lack chloroplasts because they are underground and are not exposed to sunlight. Chloroplasts are responsible for photosynthesis, which requires sunlight to convert light energy into chemical energy. Since roots are primarily responsible for absorbing water and nutrients from the soil, they do not need the ability to produce their own energy through photosynthesis. Instead, they rely on the energy produced by mitochondria to carry out their functions.
Root cells lack chloroplasts because they are underground and not exposed to sunlight. Chloroplasts are responsible for photosynthesis, which requires sunlight to convert light energy into chemical energy. Since roots are typically located in the soil and do not have access to sunlight, there is no need for them to have chloroplasts. Instead, root cells have many mitochondria, which are responsible for energy production through cellular respiration.
The correct response is: Roots are underground and are not exposed to sunlight.
Chloroplasts are the specialized organelles in plant cells that carry out photosynthesis, which is the process of converting sunlight into energy. Sunlight is the primary source of energy for photosynthesis, and chloroplasts contain pigments like chlorophyll that capture sunlight to power this process.
Since roots are underground, they are not exposed to sunlight. Therefore, there is no need for root cells to have chloroplasts because they would not be able to carry out photosynthesis without sunlight. Instead, the primary function of root cells is to absorb water and nutrients from the soil and transport them to the rest of the plant. This is why root cells do not have chloroplasts.
