To determine: The advantages of taproot system.
Introduction: The underground branching root systems are often more extensive than aerial part of plant. The extension of root depth and spread of a plant differ for another plant species and it also varies among individuals of same species. For the survival of plant, firm anchorage is essential so that the stem remains upright that enable leaves to absorb sunlight efficiently. The roots absorb water and dissolved minerals. The dissolved minerals are transported from roots to the leaves throughout the plant in the xylem.
To determine: The advantages of fibrous root system.

- What is roots and explain primary,secondary and tertiary roots?arrow_forwardDiscuss which pathway permits the passage of most solutes and water inside the roots? Which pathway allows the entry of most of the water and some of the solutes inside the root tissue? Explain how the Casparian strip creates a barrier for substance moving through this pathway and how it is circumvented.arrow_forwardThis is an example of? a.) fibrous roots b.) tap roots c.) adventitious roots d.) prop rootsarrow_forward
- Why are some roots called adventitious roots? What root system best adapted for anchorage? Why do you say so? Which among the root system is most advantageous to the plant? Explain your answer.arrow_forwardAre thicker roots (oak tree) better than thinner roots (palm tree)? Do thicker roots absorb more nutreints?arrow_forwardBoth cohesion-tension and root pressure are mechanisms for moving water in the xylem. What does it mean when it says that cohesion-tension pulls water, but root pressure pushes water?arrow_forward
- One main root, formed from the enlarging embryonic root, with many smaller lateral roots branching off it is (a) a fibrous root system (b) an adventitious root system (c) a taproot system (d) a storage root system (e) a prop root systemarrow_forwardWhy does the Casparian strip form more slowly in some areas? What are these areas called? What is the difference between a root hair and a lateral root? How does the structure of a root hair contribute to its function? What type of environmental conditions might select for a netted root system? Explain your answer.arrow_forwardPlant roots develop differently from plant shoots during primary growth. Explain: How is the formation of lateral roots different from making new branches on shoots? Why don't roots and shoots generate new primary growth the same way?arrow_forward
