Describe how a Tap Root system and Fibrous Root system is an adaptation for survival in a desert ecosystem.
Answers
Answer:
Plant roots absorb water through root hairs, which are tiny roots that extend from the root's epidermis, or the outer layer of the root. Just one cell thick, they absorb water and nutrients from the soil. Fibrous roots, with their thickly branching system and more numerous roots, have more surface area and more root hairs than taproot systems do to take in food and water. Corn (Zea mays) is an example of an annual plant with a fibrous root system that harvests large quantities of water and nutrients from the soil, allowing it to grow over 6 feet tall in a single growing season.
Answer:
Unseen and buried beneath the soil, plant roots perform functions that are necessary to a plant's life. The roots collect water and nutrients for the plant and secure it to the soil. Two basic types of root systems exist. One type is the taproot, which grows vertically and has lateral branches. The other type has fibrous, branching roots that make a network close to the soil surface. Some plants have either a taproot or fibrous roots, and other plants combine the two systems.
