Anatomy of the stem and how the vasicular bundles is arranged in both dicot and monocot
The stem is a part of a plant that serves as a support structure for leaves, flowers, and fruits. It also transports water, nutrients, and sugars throughout the plant. The stem is made up of different layers including the epidermis, cortex, vascular bundles, and pith.
Vascular bundles are clusters of xylem and phloem tissues that are responsible for the transport of water, nutrients, and sugars within the plant. In dicot stems, vascular bundles are arranged in a ring around the outer edge of the stem. This arrangement is known as a cylindrical or collateral arrangement, with xylem tissue located closer to the center and phloem tissue located towards the outside of the stem.
In monocot stems, vascular bundles are scattered throughout the stem in a random arrangement. This is known as a scattered or atactostele arrangement. Monocot stems do not have a distinct ring of vascular bundles like dicot stems.
Overall, the arrangement of vascular bundles in dicot and monocot stems plays a crucial role in the transportation of water, nutrients, and sugars within the plant.
