out of two plants that have fibrous root and taproot . How will you distinguish monocot and decot plant
Answers
Answer :
Fibrous roots grow from the main stem of the plant and does not have a primary root like the taproot. They grow downward and outward, with repeating branches to form a mass of small roots.Dicots and monocots are the two classes of flowering plants
. Dicots are usually two cotyledons.
2. Flowers are generally pentamerous or tetramerous (floral parts in sets of 5 and 4 or their multiples).
3. Pollen grains commonly have three germ pores.
4. Leaves are net veined or with reticulate venation.
5. Primary root often long lived forming tap root system. Adventitious roots occur in some cases.
6. Stem possesses concentric arrangement of tissue systems— epidermis, cortex, endodermis, perieycle, pith, etc.
7. Vascular bundles of the stem are arranged in a ring.
8. Vascular bundles of the stem possess cambium (vascular bundles open), so that secondary growth is possible.
9. In root, a pith is absent or small. The vascular bundles are few (8 or less).
10. Vessels are polygonal in outline.
Difference # Monocots:
1. In Monocots the seeds contain one cotyledon.
2. Flowers are usually timorous (floral parts in sets of three or its multiples).
3. Pollen grains generally possess a single germinal furrow.
4. The leaves possess parallel venation with a few exceptions
5. Primary root is short-lived. Tap root is absent. Instead adventitious roots are found.
6. Tissue systems are not differentiated in the stem. A ground tissue occurs.
7. Vascular bundles are scattered.
8. A cambium is absent (vascular bundle closed).
