Summary Introduction
Introduction:
The roots can be of two types which are tap roots and adventitious roots.
The roots which are formed by the non-root tissue called as Adventitious roots. These roots can produce in normal development condition and stress condition such as flooding, nutrient deprivation and wounding. These roots are also produced by the

What are the flaws ?
Meristematic tissue is the site of mitosis and therefore growth for a plant. Apical meristem is found at the tips of roots and shoots and allows them to produce flowers. Lateral meristem is found along the length of the plant and allows it to increase in width. Intercalary meristem is found in nodes along grasses and allows them to grow from the “base”, which is why grass continues to grow after it is cut.
Plants have three organs: leaves, stems, and roots. While the functions of the organs are the same between plants, the structure is different between two large groups of plants: monocots and dicots. Leaves are the site of photosynthesis. In monocots, the vascular tissue is in parallel veins like in grass. In dicots, the veins form a web or net pattern like in a maple leaf. A bulb is a modified leaf that allows the plant to store food. Stems make up the “body” of the plant and support the leaves. In monocots, vascular bundles are found randomly throughout the…
Which of the following is false? a. Stems have vascular bundles, and roots have vascular cylinders. b. Lateral roots can arise from nodes on a root. c. Primary growth (lengthening) can occur at an axillary bud. d. Apical meristem gives rise to epidermal tissue, ground tissue, and vascular tissue. e. Wood is xylem that forms during secondary growth
At the tip of each root branch, there is a root cap that protects the root apical meristem beneath.
True
False
In the fibrous root system, the primary root is replace by adventitious roots developed from the shoot tissue.
