Plants with secondary growth

Plants With Secondary Growth. The meristem concerned with this growth is known as cambium. The cambium appears in a direct continuation of a primary thickening meristem. Plant with secondary xylem is called a lignophyte. Secondary thickness takes place in three steps.

It is a usual feature of dicotyledonous and gymnospermous roots where it generally starts at a very early stage so much so that it is difficult to get the roots without secondary growth in most of the cases. One of the first groups to exhibit secondary xylem was an extinct group called the. While the principles are similar for secondary growth in roots the details are somewhat different. It occurs in some dicots but occurs very rarely in monocots. The secondary growth occurs in herbaceous and woody Lilifloarae Aloe. Herbaceous Arabidopsis plants as a model to study secondary growth The current understanding of the molecular network regulating secondary growth mainly comes from studies using the model plant Arabidopsis.

But with the commencement of secondary growth in thickness both extrastelar and intrastelar secondary growths are seen as a result of which periderm and intrastelar secondary wood formation can be recorded.

It occurs in some dicots but occurs very rarely in monocots. Vascular cambium and cork cambium. Grasses belongs to monocots. Primary tissues continue to form in the feeder roots but the supporting root structure consists of secondary tissues produced by the lateral meristems the vascular cambium and one or more cork cambiaThe usually unobserved underground root systems of most trees are as massive as the huge aerial bodies. Principle purpose of this lecture is to present on Secondary Growth of Plants. Plant with secondary xylem is called a lignophyte.
