How do Lateral Roots Develop If It Is a Taproot?
The outermost layer of the stele is an area of hibernating meristematic cells, called the pericycle. Here is where lateral roots originate. A clump forms in this area and migrates out through the two processes of mitosis and elongation. In the Shoots. Apical meristems are shaped like a dome at the tip of the terminal bud. It produces primary meristems (protoderm, procambium, ground meristem). Leafs begin as leaf primordia on the edges of the apical meristem. Axillary buds mature from isolated areas of the apical meristem outside the leaf primordia. In a bud, nodes are crowded close together because internodes are not yet elongated. At this time, most elongation is a caused by that of older shoot areas below the area of growth. Why Axillary Buds can Grow into New Branches. Vascular tissue is near the surface; therefore, without beginning deep in the stem, a new branch can “hook itself up” to the internal transport system. Primary Tissue in Shoots. There are several strands of vascular t
