Cross Section Of Monocot And Dicot Stem

While monocot root contains xylem and phloem in another manner forming a circle.

Cross section of monocot and dicot stem. The difference between vascular bundles in monocot and dicot stem are in dicot stem vascular bundles are arranged in ring whereas in monocot stem vascular bundles are scattered in ground tissues. Dicot stem vs monocot stem. To study the structural details of the stem or root of a monocot or dicot plant it is essential to be familiarized with the sectioning and staining techniques used with plant materials.

Leaves stems roots and flowers the difference between dicot and monocot root is dicot root contains xylem in the middle and phloem surrounding it. The main difference between stems of both the plants is due to the arrangement of the vascular bundle. Monocot and dicot differ from each other in four structures.

Monocot stem does not undergo secondary thickening while dicot stem undergoes secondary thickening. Note how the vascular bundles are scattered in the monocot stem and arranged in a circular pattern in the dicot stem. A cross section of tradescantia monocot stalk showing scattered vascular bundles bundle sheath sclerenchyma and epidermis.

The image above shows a cross section of the stem of a dicot plant left and monocot right. Note that the dicot seed lacks endosperm and the monocot does not have the hilum that is present in the dicot seed. These tissues form different layers in the composition of stems and roots.

Monocot plants and dicots plants possess many differences both structurally and functionally. Single layered epidermis with thick cuticle 2. Dicot stems have bundles in a ring surrounding parenchyma cells in a pith region.

The different tissues are arranged in concentric fashion 5. Plant anatomy is the general term for the study of the internal structure of plants. Hypodermis is generally collenchymatous 4.
