Conclusion of the experiment about external feature of root and sterm of monocot and dicot?

The experiment comparing the external features of the root and stem of monocots and dicots has provided several conclusions.

1. Root Structure: Monocots have fibrous root systems, while dicots have taproot systems. This difference in root structure is due to the presence of adventitious roots in monocots, which arise from the stem, and the primary root in dicots, which develops from the radicle.

2. Stem Structure: Monocots have scattered vascular bundles in their stems, while dicots have organized vascular bundles arranged in a ring. This difference in stem structure is due to the primary growth in monocots, where the vascular bundles are scattered throughout the stem, and the secondary growth in dicots, where the vascular bundles are arranged in a ring.

3. Leaf Vein Pattern: Monocots have parallel leaf veins, while dicots have reticulate leaf veins. This difference in leaf vein pattern is due to the different arrangement of vascular bundles in the leaves of monocots and dicots.

4. Cotyledons: Monocots have one cotyledon, while dicots have two cotyledons. This difference in cotyledon number is one of the key characteristics used to classify plants as monocots or dicots.

Overall, the experiment has shown that there are distinct external features that differentiate monocots and dicots, including root structure, stem structure, leaf vein pattern, and cotyledon number. These differences are important for the classification and identification of plants.
