Chloroplast play an important role I. Energy production in plant cell however some parts of a plant like roots lacks chloplasts

while other parts like leaves have a large number of chloroplasts. The main function of chloroplasts is photosynthesis, which is the process by which plants convert light energy into chemical energy in the form of glucose. Chloroplasts contain chlorophyll, a green pigment that absorbs light energy from the sun. This energy is then used to convert carbon dioxide and water into oxygen and glucose.

Since roots are typically underground and do not receive direct sunlight, they do not require as much energy production as leaves or other parts of the plant that are exposed to light. Roots primarily function to absorb water and nutrients from the soil and provide support to the plant. Therefore, chloroplasts are not present in large quantities in root cells.

However, it is important to note that while roots may lack chloroplasts, they still require energy to carry out essential metabolic processes. This energy is obtained through the breakdown of glucose produced in the photosynthetic parts of the plant and transported to the roots through the vascular system. So, even though roots do not undergo photosynthesis, they still rely on the energy produced in other parts of the plant.
