Plants are complex multicellular organisms. As cities have road systems, they have a network of "paths." Instead of cars, trains, and trucks, there is water, food, and minerals. And just like with roads, there are both one-way and two-way “streets”: paths to carry water and minerals from the soil, and paths to carry food from the leaves. There is such a part of the plant that is especially important for transportation - the stem. What is internode in biology and what is its role?
The important part of the trunk
A plant stem is one of the two structural parts of a vascular plant (a plant that has tissues for moving water and nutrients); the second is the root. The trunk is the part above the ground that provides support to the leaves and buds. It looks like the main trunk of the plant, and this is vital for its life. Knots are places on the stem where leaves and buds grow (exits or intersections), and internodes are the areas between the nodes.
People often confuse stems and shoots, but shoots are just new plants. These sprouts can include both stems and leaves. Everything that has recently grown and sticks out of the ground is considered an escape. The stems have several jobs. They provide support for the leaves, flowers, and fruits of plants. They help plants reach the light; transport water and nutrients. They also help to store nutrients and produce new plant tissue.
What are the functions of the node and internodes in plants?
Knots - this is the point of attachment of the sheet to the main trunk. The length of the stem (distance) between the two nodes is the internode. The lateral branch usually occurs on the node. The internodes are parts of the stem that also perform their functions, including adding height to plants. A tall and dwarf plant can have the same number of leaves, but only different interlobar lengths. This lengthening is usually caused by the hormone gibberellin.
Knots are points on the stem where buds, leaves and branches appear. They are important elements of the plant where transport processes, structural support, and biological processes take place. The internodes are the sections of the stem between the nodes. If the nodes are the most important "organs" of the plant; internodes are blood vessels carrying water, hormones, and food from node to node. An internode is the space between nodes or, in other words, the distance between new stems of a plant. The longer the length of the internodes, the wider and higher the plant.
