WebPlant stems, whether above or below ground, are characterized by the presence of nodes and internodes (Figure 7). Nodes are points of attachment for leaves, aerial roots, and flowers. The stem region between two nodes is called an internode. The stalk that extends from the stem to the base of the leaf is the petiole. Web2. Monocot and dicot roots contain multiple tissue layers that water moves through before reaching the root’s central vascular cylinder. Water and nutrients from the surrounding soil pass through the root’s tissues until they reach the central vascular cylinder. The root’s xylem transports the water and nutrients upward toward the stem.

WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
