Twist of Fate: Ribosomal Stress Reprograms Root Hair Patterning

WebThe role of root hair cells is to absorb water and mineral ions. Therefore they have a large surface area to increase the rate of water absorption. Root hair cells also have a large amount of mitochondria which provide more energy for the active transport of mineral ions. These two specialisations allow for more efficient uptake. Web12 de mai. de 2024 · The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily. Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
