Which among the following is correct about the anatomy of monocot root...
Anatomy of Monocot Root
Introduction:
The root is an essential part of the plant that anchors it to the ground and absorbs water and nutrients from the soil. The monocot root is one of the two types of roots found in plants, the other being dicot root. Monocot roots have a distinct anatomy that sets them apart from dicot roots.
Anatomical Features of Monocot Root:
Presence of Cambium:
- Option A states that a cambium is present between the xylem and phloem in the monocot root, and this statement is correct.
- Cambium is a meristematic tissue responsible for secondary growth in plants.
- In monocot roots, the vascular bundles are scattered, and they lack a distinct cambium ring as seen in dicot roots.
- However, a few parenchyma cells between the xylem and phloem in monocot roots can regain meristematic activity and form a secondary meristem called the inter-fascicular cambium.
- This cambium allows for some amount of secondary growth in the monocot root.
Endodermis and the Casparian strip:
- Option B states that the endodermis of the monocot root has a Casparian strip to prevent water leakage and the invasion of foreign particles, and this statement is incorrect.
- The Casparian strip is a band of suberin, a waxy substance, found in the endodermal cells of dicot roots.
- It acts as a waterproof barrier, forcing water and solutes to pass through the selectively permeable plasma membranes of endodermal cells.
- Monocot roots also have an endodermis, but they lack the Casparian strip.
Channels Connecting Parenchyma Cells:
- Option C states that the channels connecting the parenchyma cells in monocot roots are called plasmodesmata, and this statement is incorrect.
- Plasmodesmata are cytoplasmic channels that connect the cytoplasm of adjacent plant cells, allowing for communication and transport of materials between cells.
- However, they are not specifically related to the monocot root anatomy.
Outermost Layer of the Root:
- Option D states that the outermost layer in the root is called the epidermis, and this statement is correct.
- The epidermis is the outermost layer of cells that covers the root surface.
- It is usually a single layer of cells that protects the root from water loss and mechanical damage.
- The epidermis may also have root hairs, which increase the surface area for absorption of water and nutrients.
Conclusion:
The correct statement about the anatomy of the monocot root is that a cambium is present between the xylem and phloem. The other options, such as the presence of a Casparian strip in the endodermis, channels connecting parenchyma cells called plasmodesmata, are incorrect. The outermost layer of the root is indeed called the epidermis.
