Pericycle
WebApr 7, 2024 · Pericycle The tissue that occurs between the endodermis and the vascular bundles is known as the pericycle. The pericycle in the dicot stem is multilayered and serves to protect the underlying tissues. Because the pericycle's cells are sclerenchymatous, it's sometimes referred to as hardback. WebTaken together, our data show that the pericycle is a heterogeneous cell layer with two groups of cells set up in the root meristem by the same genetic pathway controlling the diarch organization of the vasculature.

WebThe pericycle is a heterogeneous, non-vascular and non-conducting layer made up of parenchymatous cells. They are divided into two populations. One at the xylem pole and … WebConiferous plant species that thrive in cold environments, like spruce, fir, and pine, have leaves that are reduced in size and needle-like in appearance. These needle-like leaves have sunken stomata (pits that allow gas exchange) and a smaller surface area: two attributes that aid in reducing water loss.
