How do plants that lack a secondary growth increase girth?
Plants that lack secondary growth increase girth through primary growth, which involves cell division and expansion in the primary tissues of the plant (such as the primary xylem and phloem). These plants rely on the activity of their apical meristems to produce new cells that allow for a limited increase in girth over time.
What growth increases the girth of stems and roots?
Secondary growth, carried out by the vascular cambium, increases the girth of stems and roots. This process involves the production of secondary xylem towards the inside and secondary phloem towards the outside of the plant. The continuous activity of the vascular cambium results in the thickening of stems and roots over time.
What is the main purpose of meristem tissue?
Meristem tissue is responsible for plant growth and development. It generates new cells for primary and secondary growth, allowing plants to grow in length and girth. Meristems also play a key role in repairing damage and regenerating tissues in plants.
What is the diffeence between primary and secundary growth?
Primary growth refers to the lengthening of plant stems and roots, primarily through cell division at the tips of these structures. Secondary growth, on the other hand, involves the thickening of stems and roots through the lateral growth of vascular tissue, resulting in an increase in girth or diameter.
Growth tissue between xylem and phloem that produces additional xylem and phloem cell?
The tissue you are referring to is called vascular cambium. Vascular cambium is a meristematic tissue that is responsible for secondary growth in plants, producing additional xylem towards the inside and phloem towards the outside, contributing to the increase in girth of woody plants.

Do Woody plants lack secondary growth?
No, woody plants do not lack secondary growth. Secondary growth is the process by which plants increase their girth through the production of secondary tissues such as wood and bark, which woody plants exhibit. This growth allows woody plants to increase in size and longevity.

What does the primary growth of plant add and while secondary growth adds?
Primary growth in plants adds length to the stems and roots through cell division in the apical meristems. Secondary growth, on the other hand, adds girth to the stems and roots through cell division in the lateral meristems, such as vascular and cork cambium.
Which group of plant has secondary growth and which never do?
Gymnosperms and dicots have secondary growth, which is the ability to grow in girth and produce wood. In contrast, monocots do not exhibit secondary growth and rely on primary growth for their development.
What is the result of secondary growth in dicot plants?
Secondary growth in dicot plants leads to an increase in girth or thickness of the stems and roots. This is primarily achieved through the activity of the vascular cambium, which produces secondary xylem and phloem, resulting in the formation of wood in the stem and root. This process contributes to structural support and allows for the transport of water, nutrients, and sugars throughout the plant.
What growth increases the girth of stems and roots?
Secondary growth, carried out by the vascular cambium, increases the girth of stems and roots. This process involves the production of secondary xylem towards the inside and secondary phloem towards the outside of the plant. The continuous activity of the vascular cambium results in the thickening of stems and roots over time.
What tissues produce secondary growth in plants?
Lateral meristems. Usually, vascular tissue is produced in the center of the stalk and grows outward continually. The vascular cambium is responsible for the new vascular tissue and the cork cambium produces new dermal coverings.
What tissue produces cells that add to the girth of the root?
The vascular cambium is the tissue responsible for producing cells that add to the girth of the root. It is a meristematic tissue located between the xylem and phloem in dicot plants. The cells produced by the vascular cambium differentiate into secondary xylem (wood) towards the inside and secondary phloem towards the outside, thus contributing to the increase in girth of the root.
Define meristems and explain its role in primary and secondary stem growth?
Meristems are areas of cell division that are found at the tip of the stem and just behind the tip of the root of a plant. They provide the cells that are needed in plants to produce height. They also aid secondary stem growth by forming additional cells to increase width.
