Next: (a)Name two cardiovascular diseases. It is also adapted to hold the plant firmly and provide support (anchor) to the plant in the soil. Plants absorb water from the soil by osmosis. O They contract which helps the muscle to move. A number of earlier studies had established a connection between ABA and … root hair cells are found in plants and their function is to absorb water and minerals from the surrounding soil. #64 Adaptations of the leaf, stem and root to different environments. Veins have valves which helps to prevent backflow of blood since the blood moves with low pressure. Veins have narrow lumen on their walls which enables blood to flow in low presurre. Thus, the region of cell maturation is also known as the root hair zone. The job of a Root Hair Cell is to keep the plant from dieing. What is a root hair cell’s adaptation to its function? Root hairs are an extension of the root. They also have a large amount of Mitochondria, which provide more energy for Active Transport. Plants absorb water from the soil by osmosis. The root hair cells are delicate structures on the root of a plant which live only two to three weeks. 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. They have a large surface area, due to their hair-like projections, which eases uptake. They keep the plant in place and help stabilize the soil around it. The cells attain maturity when they reach this zone. 1. Following are some of the morphological characters of xerophytes. A Root Hair Cell : It absorbs water and nutrients from the soil. (June 2018, 5 marks), Write down the difference between aerobic respiration and anaerobic respiration in humans, and explain the process and elimination of the 'oxygen debt' . 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. Most modifications are adaptations to very dry (arid) environments. Their development occurs in four phases: cell fate specification, initiation, subsequent tip growth and maturation (Fig. They also have a large amount of Mitochondria, which provide more energy for Active Transport. The function of the hair root is to feed nutrients to the hair. Which of the following are listed in the order of modified root, stem, and leaf? ADAPTATIONS.
