They are also filled with many mitochondria so they are very well specialised for active transport of mineral ions from the soil and into the roots. They absorb mineral ions by active transport, against the concentration gradient. These acids assist solubilizing minerals into ionic form; this makes the minerals easier to carry and transport through the roots of the plant. Large surface area Permeable and thin cell membrane No chloroplast. One of the most crucial adaptations that sperm have evolved is their flagella, which propel them as they travel toward unfertilized ova. The longest symplastic pathway would be an uptake into the root hair cells of the epidermis, repeated transport through the cytoplasmic bridges of plasmodesmata, and export into the xylem (Figure 1F). Water passes from the soil water to the root hair cell's, . So there is more space for water to be absorbed. It is also adapted to hold the plant firmly and provide support (anchor) to the plant in the soil. Answer (1 of 6): A root hair cells job is to provide water and nutrition for a plant. Xylem cells grow within the lengthening tips of roots and shoots. They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water. Answer. The evolution of roots and root hairs was a crucial innovation that contributed to the adaptation of plants to a terrestrial environment. Root hair cells help supply sufficient water by growing large, thin extensions, which increase their surface area dramatically. These are plants which have special adaptations to survive in drying, environmental conditions where many plants would become desiccated and die.
