Answer:
Taproot systems feature a single, thick primary root, called the taproot, with smaller secondary roots growing out from the sides. The taproot may penetrate as many as 60 meters (almost 200 feet) below the ground surface. It can plumb very deep water sources and store a lot of food to help the plant survive drought and other environmental extremes. The taproot also anchors the plant very securely in the ground.
Fibrous root systems have many small branching roots, called fibrous roots, but no large primary root. The huge number of threadlike roots increases the surface area for absorption of water and minerals, but fibrous roots anchor the plant less securely
Explanation:
Active transport requires energy because it moves molecules across a membrane to a region of lower to higher concentration which is often against their concentration gradient or has an obstructing factor.
Answer:
High mass stars have to generate a lot of energy in order to balance the force of gravity. Therefore they are very hot and luminous. That explains their position high on the Main Sequence. On the other hand, low mass stars have to generate little energy in order to balance the force due to gravity.
