WebbThe secondary growth occurs in herbaceous and woody Lilifloarae (Aloe. Sansevieria, Yucca, Agave, Dracaena) and other groups of monocots. The meristem concerned with this growth is known as cambium. The cambium appears in a direct continuation of a primary thickening meristem. However, the cambium functions in the part of the axis.

Webb4 maj 2024 · The lignified xylem and phloem fibers break down far more slowly than the parenchyma cells of the leaf. As the rest of the leaf tissues decompose, the lignified vascular tissue is left behind. This reveals the netted pattern of increasingly smaller side branches found in eudicot leaves. WebbThese large, bubble-like cells, located just beneath the epidermis, are thought to help the leaf bend or fold. This is important because folding the leaf changes its exposure to light and the amount of water it retains. Lastly, monocot leaves have stomata on both their upper and lower surfaces. chipping cross handed https://tlrpromotions.com
