Answer 2

Answer:

1) Root systems are mainly of two types (Figure 1). Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise.

2) A fibrous root system forms a dense network of roots that is closer to the soil surface. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems.

3)You can propagate the plant by snipping off the plantlets and planting them with their roots under the soil. ... Their aerial roots are meant to stay above ground where they gather nutrients from the air and from surface water and debris. Epiphytic orchids are an example of this type of plant.
