Internode - what is it in biology? Role and functions

Plants are complex multicellular organisms. Just 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 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 an internode in biology and what is its role?

internode is in biology

Important part of the trunk

The stem of a plant is one of the two structural parts of a vascular plant (a plant that has tissues to move water and nutrients); the second is the root. The trunk is the part above the ground that provides support for the leaves and buds. It's like the main highway of a plant, and it's vitalimportant to his life. Nodes are the places on the stem where leaves and buds grow (outlets or intersections), while internodes are the areas between nodes.

People often confuse stems and shoots, but shoots are just new plants. These sprouts may include both stems and leaves. Anything that has recently grown and sticks out of the ground is considered an escape. Stems have multiple jobs. They provide support for the leaves, flowers, and fruits of plants. They help plants reach light; transport water and nutrients. They also help 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 leaf to the main trunk. The stem length (distance) between two nodes is the internode. A side branch usually originates at a node. Internodes are parts of the stem that also perform their functions, among which is adding height to plants. Tall and dwarf plants may have the same number of leaves, but only different interlobular lengths. This lengthening is usually caused by the hormone gibberellin.

Knots are the points on the stem where buds, leaves and branches appear. They are essential plant elements where transport, structural support and biological processes take place. 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 that carry water, hormones, and food from node to node. The interstitial isthe space between the nodes or, in other words, the distance between the new stems of the plant. The longer the internodes, the wider and taller the plant.
