No, they store starch reserves in their roots Why do you eat roots of the plant? The root hair cells vary between 15-17 micrometers in diameter and 80-1500 micrometers in length. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. These cells have large vacuoles for the sake of maximum storage. So they are able to move to sites of infection easily .They are found in tissues as well as blood , Cytoplasm ,contains haemoglobin which are what give blood its red colour. They absorb mineral ions by active transport, against the concentration gradient. This happens because the soil water has a higher concentration than the root hair cell cytoplasm. Root hairs are also important for nutrient uptake as they are main interface between plants and mycorrhizal fungi. hair root, while the portion you see protruding from the head is This region characterizes high metabolic function and is involved solely in the mitotic activity of undifferentiated meristems. Animal Coordination, Control & Homeostasis, 7.1.6 Hormones & Assisted Reproductive Technology, 7.2.9 Regulating Blood Glucose Concentration, 8.1.2 Factors Affecting the Rate of Diffusion, 8.2.2 Practical: Investigating Respiration, 9.4.3 Benefits of Maintaining Biodiversity, Root hairs are single-celled extensions of epidermis cells in the root, They grow between soil particles and absorb water and minerals from the soil, This increases the rate of the absorption of, The high proportion of dissolved minerals and sugars in the cytoplasm (of the root hair cell) gives it a low water potential (less watery), This causes water to move into the root hair cell by. Apoplast means the nonliving space surrounding cells i.e. Outer membrane. A Vacuole stores water and other substances Glucose is often stored in plants in the form of starch, which is composed of glucose molecules linked in long chains.
