Root hair cells-pumping in mineral ions
|
Detailed explanation-1: -Examples of Active Transport Phagocytosis of bacteria by Macrophages. Movement of Ca2+ ions out of cardiac muscle cells. Transportation of amino acids across the intestinal lining in the human gut. Secretion of proteins like enzymes, peptide hormones, and antibodies from different cells.
Detailed explanation-2: -Active transport in plants For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. Active transport then occurs across the root so that the plant takes in the ions it needs from the soil around it.
Detailed explanation-3: -Root hair cells They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Detailed explanation-4: -Plants use active transport in the following ways: Photosynthesis sugars make their way from the leaf to the fruit. Calcium moves between cells with the use of ATP energy. Minerals pass via a stem on their way to different areas of the plants. Root pressure transports water from the plant roots to other plant cells.
