What is a plant cortex? The name monocot essentially stems from the amount of cotyledons that are present in the leaf. The Latin term mono means one, which is why the monocot only has one cotyledon. In Latin, the prefix di means many and the dicot leaves always have more than one cotyledon in them.
Cut across a dicot's stem, and the vascular bundles inside are arranged in concentric rings. The vast majority of trees are dicots, and tree rings are such concentric rings. When a dicot's seed sprouts, the seedling raises two leaves, or cotyledons, above the ground, with the future stem arising between them.This is very unlike the monocot's single cotyledon.About 170,000 dicot species are known worldwide.ut across a monocot's stem and the water-bearing tubes, or vascular bundles, inside are scattered throughout the pith, not arranged in concentric rings like the rings of a tree. When a monocot's seed sprouts, the first leaf up is a single spike looking like a simple blade of grass arising from the soil.
