Plants with straight roots: The root systems of most dicots and gymnosperms. Such as various beans, sunflowers, dandelions, cotton, rape, moonflowers, chrysanthemums, poplars, willows, peaches, plums, plums, apricots.
Plants with fibrous root systems: The root systems of many monocots.
As. 1.Poaceous plants β rice, wheat, barley, millet, millet, corn, sorghum.
2.bulb plants.
Green onions, shallots, garlic, leeks, daffodils, lilies, and much more, you can go.

The difference between straight roots and fibrous roots lies in the presence or absence of taproots and lateral roots.
Straight root system: The root system of the plant is composed of an obvious taproot (formed by radicle) and lateral roots at all levels, most dicots (most vegetables) have a straight root system, the straight root system is characterized by obvious taproot, the total taproot has lateral roots, and the primary and secondary are distinct.
The root system of a tree grown by vegetative propagation such as cuttings and strips is composed of adventitious roots, and although there is no real taproot, one or two adventitious roots tend to be stout, similar in appearance to taproot, and have the form of a straight root system, which is also customarily regarded as a straight root system.
Fibrous root system: The fibrous root system of plants is composed of many adventitious roots of similar thickness, and the main root (onion) cannot be clearly distinguished from the root system.
Pathways for the root system to absorb water:
Plant roots absorb water mainly through root hairs, cortex, endothelium, and then enter the duct through the parenchyma cells of the middle column. There are two pathways of water in the radial operation of water in the root: apoplast and symplast, and the so-called apoplast refers to the process of water moving through the cell wall, intercellular space, intercellular layer and the cavity of the duct.
The movement of water in the apoplast does not cross any membrane, so the movement resistance is small, the movement speed is fast, but the apoplast in the middle is often discontinuous, he is separated into two regions by the Kjeldahl band of the endothelium, and the outside of the endothelial layer, including the root hair, the intercellular layer of the cortex, the cell wall and the intercellular space, is called the exoplastic.
The endothelial layer, including the mature ducts and the cell wall of each part of the middle column, is called the endopatope, so the passage of water from the outer apoplast into the inner apoplast must pass through the symplast pathway of the endothelial cells.
-
Straight root system: The taproot is longer and thicker, and the lateral root is shorter and thinr, and there is a clear difference between the taproot and the lateral root.
Generally speaking, the root system of dicots is a straight root system (such as the root system of Phaseolus vulgaris).
Fibrous root system: The main root system is underdeveloped, and the fibrous root system is mainly composed of adventitious roots.
Generally speaking, the root system of monocots is fibrous root system (such as the root system of wheat).
-
Straight root system (taproot system) taproot is well-developed and obvious, which is easily distinguished from lateral roots, and the root system composed of this taproot and its various levels of lateral roots is called straight root system.
The taproot of monocots stops growing or dies soon after birth, and many adventitious roots of equal thickness are born on the nodes of the hypocotyl and the base of the stem, and then lateral roots are generated from the adventitious roots, and the whole root system is flocculent in shape, so it is called the fibrous root system.

Summary. Plants with straight roots include dandelions, soybeans, tomatoes, pumpkins, peach trees, cabbage, turnips, potatoes, cedars, and wisteria.
Plants with straight roots and fibrous roots, to name 10 each.

Fibrous root plants are; Wheat, rice, corn, peanuts, shallots, garlic, lilies, daffodils, alfalfa, palms.

1. The taproot of the straight root system is well developed, and it is easy to distinguish it from the lateral root, and the root system composed of this taproot and its lateral roots at all levels is called the straight root system. The straight root system is found in dicots, which is characterized by a distinct and well-developed taproot with a vertical downward orientation, and the lateral roots are grape-like around the taproot.
2. The taproot of monocots ceased to grow or died soon after birth, and many adventitious roots of equal thickness were born on the nodes of the hypocotyl and the base of the stem, and then the lateral roots were generated from the adventitious roots, and the whole root system was flocculent in shape, so it was called the fibrous root system, which was composed of seed roots and adventitious roots.
