<em>The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis they do not contain chloroplasts.</em></h2>

Answer:
photosynthesis
Explanation:
Photosynthesis is the process used by algae, green plants and some types of bacteria to convert solar energy into chemical energy. During photosynthesis, carbon dioxide (CO2) is consumed and oxygen (O2) is released. In the primitive Earth, the photosynthetic marine organisms helped to replace atmospheric CO2 with O2, which was one of the most important gas components in the atmosphere. Moreover, the ozone (O3) is generated when O2 reacts with sunlight. In the stratosphere, this gas (O3) formed a layer that is capable of filtering ultraviolet harmful radiation.
