Fibrous root system

A fibrous root system (sometimes also called adventitious root system) is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. A fibrous root system is universal in monocotyledonous plants and ferns.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30-50 m tall has a root system that extends horizontally in all directions as far as the tree is tall or more, but well over 95% of the roots are in the top 50 cm depth of soil.

Question:

Answers:The primary root is the first-formed, main root, originating from the radicle of a seed embryo. In plants, not developing or dieing back this root, arise fibrous roots, often from stem or leaf tissue. That`s why they are considered as adventitious. http://www.cactus-art.biz/note-book/Dictionary/Dictionary_R/dictionary_root_system_apparatus.htm

Question:

Answers:Fiberous roots are in the ground to anchor the plant and absorb water and nutrients. They are numerous and thin. Turf grass is a good example. Aerial roots are suspended in the air and do not go into the soil. The best example of that is an orchid. They normally sit in the fork of a tree in the rainforset many feet from the ground and absorb water directly from the air. This explains why orchids are in the humid rainforests but not in deserts.

Question:It helps a plant climb along a surface. B. It provides food for animals. C. It stores nutrients. D. It pulls nutrients from the soil. E. It prevents soil from washing away.

Answers:E... Plants with fibrous root systems are used to prevent soil erosion.

Question:2. What soil conditions might fibrous roots prefer and what conditions might the tap root prefer? 3. What type of root structure would you think a very large plant be best with? Explain your answer.

Answers:1. There are a whole lot of secondary roots instead of a big primary root. They spread out through the soil instead of just going down through the soil. So they hold the soil together a lot better. 2. ? 3. I think a fibrous root system might be more sturdy than a taproot system. It might "grip" the soil better and be more stable.

The Square Root of Minus One :Subtract from the size of your room the size of your cupboard. Minus one cupboard. The sides of the cupboard measure: The square root of minus one. This is supposed to be an "imaginary" number because we supposedly can't draw a practical diagram of it or find a practical example. But we can. So there. Soundtrack made in VSThost.
