Predict what would happen if root hair were not there at all

If root hairs were not there at all, the plant's ability to absorb water and nutrients from the soil would be severely compromised. This can result in stunted growth, nutrient deficiencies, and ultimately, death. Plants need water and nutrients to carry out essential functions such as photosynthesis and reproduction. Without root hairs, the plant would have difficulty accessing the necessary resources, leading to a decline in overall health and vitality.
