Parts of a Root Worksheet

Roots are an essential part of a plant's structure and function. For educators or parents looking to teach students about the different parts of a root, worksheets can be a valuable resource. These worksheets offer a hands-on way to learn and reinforce the knowledge of root anatomy, making it easier for students to understand and retain the information.

What is the outermost layer of a root called?

The outermost layer of a root is called the root epidermis.

What is the middle layer of a root responsible for transporting water and nutrients?

The middle layer of a root responsible for transporting water and nutrients is called the cortex.

What is the innermost layer of a root that produces new cells for growth?

The innermost layer of a root that produces new cells for growth is called the root meristem or the apical meristem. This region contains actively dividing cells that give rise to the various tissues and structures of the root, enabling it to grow longer and expand into the soil for water and nutrients absorption.

What is the protective covering at the tip of a root called?

The protective covering at the tip of a root is called the root cap. It is a structure composed of living parenchyma cells that help to protect the delicate meristem tissues as the root pushes through the soil during growth.

What are the tiny, hair-like structures on the surface of a root that increase its surface area for absorption?

The tiny, hair-like structures on the surface of a root that increase its surface area for absorption are called root hairs. These structures play a crucial role in absorbing water and nutrients from the soil, as their large surface area allows for more efficient uptake of essential materials needed for plant growth and development.

What is the region of a root where secondary growth occurs?

The region where secondary growth occurs in roots is the vascular cambium, which is a lateral meristem located between the xylem and phloem tissues. This region is responsible for producing secondary xylem (wood) and secondary phloem, leading to an increase in the girth or diameter of the root over time.

What is the storage organ of a root that stores food and water?

The storage organ of a root that stores food and water is called a taproot. The taproot is typically thick and fleshy, allowing it to store nutrients and water for the plant to use during times of scarcity.

What is the region of a root where root hairs are present?

Root hairs are present in the region of the root known as the root hair zone, which is located near the tip of the root. This region is responsible for increasing the surface area of the root system, allowing for better absorption of water and nutrients from the soil.

What is the area between the root cap and the region of cell elongation called?

The region between the root cap and the region of cell elongation in a plant root is called the zone of cell division. In this zone, new cells are continuously being produced, which then elongate and differentiate as they move towards the region of cell elongation, where they grow in length.

What is the primary function of a root?

The primary function of a root is to anchor the plant in the soil, absorb water and nutrients from the soil, and provide support for the above-ground parts of the plant. Roots also store food and water, and in some plants, can serve as a place for the synthesis of certain hormones and other compounds essential for growth and development.
