What is one of the main roles of meristem tissue?

To store nutrients
To enable plant growth
To transport sugars
To protect the plant from pests

The correct answer is: To enable plant growth

Meristem tissue is vital in plants because it contains undifferentiated cells that have the ability to divide and differentiate into various types of plant cells. This tissue is primarily found in specific regions of the plant, such as the tips of roots and shoots, where growth occurs. By facilitating the continuous growth of these areas, meristem tissues play a crucial role in increasing the size and complexity of the plant throughout its life. This growth can include the elongation of roots and shoots, as well as the development of new leaves and flowers, making meristem tissue essential for the overall growth of the plant. While some of the other roles listed, such as nutrient storage or protecting the plant from pests, are important functions in overall plant health, they are not the primary role of meristem tissue, which focuses specifically on growth and development.
