Cuneiform script (/kjuËËniËáµ»fÉËrm/ kew-NEE-i-form or /ËkjuËnáµ»fÉËrm/ KEW-ni-form), one of the earliest systems of writing, was invented by the Sumerians. It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus. The name cuneiform itself simply means wedge shaped.
â¢ Monocot seeds contain one cotyledon while dicot seeds contain two cotyledons. â¢ Cotyledon of monocot seed is generally long and thin, whereas cotyledons of dicot seed are thick and fleshy. â¢ The embryos of dicot seed are large while that of monocot seeds are small. â¢ Dicot seeds contain large plumule and folded plumule leaves, whereas monocot seeds contain very small plumule and rolled plumule leaves. â¢ Hilum and micropyle of dicot seeds are clearly visible while that of monocot seeds are not visible.
What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots? In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vas â¦ cular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
