What two meristematic tissues produce secondary growth?
The two meristematic tissues that produce secondary growth are the vascular cambium and the cork cambium. The vascular cambium is responsible for the production of secondary xylem (wood) and secondary phloem, while the cork cambium generates the periderm, which includes cork tissue. Together, these tissues contribute to the increase in thickness of stems and roots in 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.
How do the lack of secondary growth increase stem width?
Lack of secondary growth in plants means that the stems do not thicken through the formation of additional vascular tissues, such as xylem and phloem, which typically occurs in woody plants. Instead, these plants may rely on primary growth, which primarily elongates stems and leaves. In some herbaceous plants, the absence of secondary growth can lead to a wider stem base due to the accumulation of water and nutrients within the existing tissues, promoting a more robust stem structure. However, this width is generally limited compared to woody plants with significant secondary growth.
Anamolus secondary growth in achyranthus plant?
Achyranthes, a genus of flowering plants in the Amaranthaceae family, exhibits anomalous secondary growth, which is characterized by irregular patterns of secondary tissue formation. Unlike typical dicotyledonous plants that have a well-defined vascular cambium, Achyranthes can develop multiple cambia and produce additional vascular tissues in various patterns, leading to a unique stem structure. This adaptation allows for increased support and nutrient transport, enhancing the plant's resilience and growth in diverse environments. Such growth patterns are particularly interesting for studying plant adaptability and evolution.
What is the secondary growth of a tomato plants?
Tomato plants primarily exhibit primary growth, which involves the elongation of stems and roots. However, they can also show limited secondary growth, primarily in the form of thickening of stems due to the activity of the vascular cambium, though this is not as pronounced as in woody plants. This secondary growth allows for increased support and nutrient transport as the plant matures. Overall, while secondary growth occurs, it is not a significant feature of tomato plants compared to their primary growth.
What two meristematic tissues produce secondary growth?
The two meristematic tissues that produce secondary growth are the vascular cambium and the cork cambium. The vascular cambium is responsible for the production of secondary xylem (wood) and secondary phloem, while the cork cambium generates the periderm, which includes cork tissue. Together, these tissues contribute to the increase in thickness of stems and roots in woody plants.
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.
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.

Do mosses have secondary growth?
No, mosses do not have secondary growth like vascular plants. They lack the vascular tissues needed for secondary growth, such as xylem and phloem, which are responsible for transporting water and nutrients throughout the plant. Mosses rely on diffusion to transport water and nutrients, limiting their size and complexity.
Do herbaceous plants lack secondary or primary growth?
Herbaceous plants primarily exhibit primary growth but typically lack significant secondary growth. Primary growth allows them to increase in height and produce new leaves and flowers, while secondary growth, which thickens stems and roots, is more characteristic of woody plants. Consequently, herbaceous plants remain relatively soft and non-woody throughout their life cycle.
What tissues arise from the active cell division of the vascular cambium?
The vascular cambium undergoes active cell division to produce secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside. This results in the growth of woody tissues in trees and other woody plants.
Anamolus secondary growth in achyranthus plant?
Achyranthes, a genus of flowering plants in the Amaranthaceae family, exhibits anomalous secondary growth, which is characterized by irregular patterns of secondary tissue formation.

What is the function of the cambium?
The cambium is a layer of cells in plants that is responsible for lateral growth, producing new xylem and phloem cells. It plays a key role in secondary growth, increasing the width of stems and roots.
What does the stem do for the stem?
Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness
