True or False. In both monocots and eudicots, most of the root is composed of cortex cells.

Analysis of the Statement

1. Understanding Monocots and Eudicots:

   • Monocots (e.g., grasses, lilies) and eudicots (e.g., roses, sunflowers) are two major groups of flowering plants. They have differing structures in various plant parts, including roots.

2. Root Structure:

   • In both monocots and eudicots, roots consist of several tissue types: the epidermis, cortex, endodermis, pericycle, and vascular tissue (xylem and phloem).
   • The cortex is the layer of tissue that lies between the epidermis and the vascular core, primarily composed of parenchyma cells, which can store starch and help in transport.

3. Cortex Dominance:

   • It is generally true that the cortex makes up a significant portion of the root's volume in both monocots and eudicots.

Conclusion

Given that the cortex is a prominent part of the root structure in both monocots and eudicots, the statement is True. In both groups, the root predominantly consists of cortex cells, playing essential roles in storage and transport.
