Question

Instructions: Try to uproot one living dicot (ex. dandelion) and monocot (ex. grass) representative plant.

Observe the roots of each plant and characterize as follows:

A. Type of root system

B. Presence of primary root

C. Presence of lateral roots

D. Presence of adventitious roots

Note: Indicate the name of the plant, the root system it exhibits and the parts present.

Tabulate the result of your observation using the table below. Answer the related questions below.

Root Characteristics	Monocot Specimen (Name)	Dicot Specimen (Name)
Type of root system
Presence of primary root
Presence of lateral roots
Presence of adventitious roots

1. Which root system gives better anchorage and why?

2. List down five general features of roots you can recognize in both of your specimens.

Features Features The presence of a single cotyledon in the seedling is the most common way to identify monocot plants. Veins that run parallel to the length of the leaves and flower sections that are arranged in a three or six-fold symmetry are some of the anatomical characteristics shared by monocots. Monocots have very little true woody tissue and an adventitious root system. They lack a typical cambium and have scattered vascular bundles.
