The job of both red blood cells and root hair cells is absorption. 1). root hair cells are found in plants and their function is to absorb water and minerals from the surrounding soil. Red blood cells absorb oxygen through pulmonary veins and their capillaries in the lungs. They also have a large amount of Mitochondria, which provide more energy for Active Transport. Root Hair Cell Function. Fibrous Roots Taproots Fibrous roots are typically found in plants like grass. These acids assist solubilizing minerals into ionic form; this makes the minerals easier to carry and transport through the roots of the plant. This allows more active transport of mineral ions to take place so the plant is able to take in as many important mineral ions as possible e.g. Storage roots, stems, and leaves are some of the evolutionary adaptations of plants. Plants which live in extreme environments have adaptations to control their transpiration rate. This enables the hair to grow. Red Blood Cell Function. As the root grows, new root hairs develop and older one shrivel and sloughed off. These cells constantly form at the top of the root of the plant, so as others die, new ones take their place. Root hair cells have a very large surface area due to them being very long and having hair like projections. This type of root system is different than taproots because there is no main root which other roots grow off of. The absorbed water is transported through the roots to the rest of the plant where it is used for different purposes. 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. plants have an extensive network of root hirs so they occupy a large surface area, so plants can effectively absorb water and minerals from the soil. The cells attain maturity when they reach this zone. The primary function of leaves is to collect sunlight and make food by photosynthesis. This is because the mitochondria provide energy (in the … Explain how the guard cells are adapted to their functions. How is the root hair cell adapted to its function?
