Cambium – Definition & Detailed Explanation – Botanical Terms Glossary

What is Cambium?

Cambium is a type of plant tissue that is responsible for the growth of vascular plants. It is a thin layer of cells located between the xylem and phloem in the stem and roots of a plant. Cambium is a meristematic tissue, meaning it is made up of cells that have the ability to divide and differentiate into various types of cells.

Where is Cambium located in a plant?

Cambium is located in the vascular bundles of a plant, specifically between the xylem and phloem. In stems, cambium is found in a cylindrical layer just beneath the bark, known as the vascular cambium. In roots, cambium is located in the center of the root, between the xylem and phloem, known as the interfascicular cambium.

How does Cambium function in plant growth?

Cambium plays a crucial role in the growth of plants by producing new cells that differentiate into xylem and phloem tissues. The cells in the cambium layer divide rapidly, with one daughter cell differentiating into xylem tissue and the other into phloem tissue. This process allows for the expansion of the vascular system in plants, enabling them to transport water, nutrients, and sugars throughout the plant.

What are the different types of Cambium?

There are two main types of cambium in plants: vascular cambium and cork cambium. Vascular cambium is responsible for the growth of secondary xylem and phloem, which increases the girth of stems and roots. Cork cambium, also known as phellogen, is responsible for the production of cork cells in the outer bark of a plant, providing protection and insulation.

How does Cambium contribute to the formation of new plant tissues?

Cambium contributes to the formation of new plant tissues by undergoing cell division and differentiation. As the cambium cells divide, they give rise to new xylem cells towards the inside of the stem or root and new phloem cells towards the outside. This continuous growth and differentiation of cambium cells result in the formation of secondary xylem and phloem tissues, which contribute to the increase in girth and strength of the plant.

What is the importance of Cambium in plant development?

Cambium is essential for the development and growth of plants. It is responsible for the production of secondary xylem and phloem, which provide structural support and allow for the transport of water and nutrients throughout the plant. Without cambium, plants would not be able to grow in girth, resulting in stunted growth and limited vascular function. Cambium also plays a role in wound healing and response to environmental stress, making it a vital tissue for plant survival and adaptation.
