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.
Why do monocot plants not show secondary growth?
In a monocot stem, vascular bundles are scattered throughout the stem. However, because the of the lack of vascular cambium, no secondary growth occurs in the monocot stem. As a result of increased cell size, the monocot stem will only increase in height only.
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.
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 is precambium?
The precambium is a layer of meristematic tissue found between the primary xylem and phloem in vascular plants. It is responsible for the production of secondary vascular tissue in the form of secondary xylem (wood) and secondary phloem.
What part of a plant produces secondary growth?
The vascular cambium, a layer of cells between the xylem and phloem tissues in the stem, is responsible for producing secondary growth in plants. This results in the thickening of the stem and roots as new layers of xylem and phloem are added.
What is the function of the vascular cambium in secoundary growth?
The vascular cambium is responsible for producing secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside, contributing to the growth in girth of woody plants. It plays a crucial role in secondary growth, increasing the diameter of stems and roots in dicot plants.
What are the two kinds of meristems?
The two kinds of meristems are apical meristem, located at the tips of roots and shoots, responsible for primary growth, and lateral meristem, found in the vascular cambium and cork cambium, responsible for secondary growth in plants.
How would plants that exhibit secondary growth differ in size and structure from plants that exhibit only primary growth?
someone please answer this question...
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.
Where is the location of cambium in plant?
The cambium is a layer of actively dividing cells located between the xylem and phloem in vascular plants, mainly in the stems and roots. Its primary function is to produce new cells for secondary growth, resulting in the thickening of the plant body.
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.
