Monocotyledons:<span>Embryos have a single seed leaf, referred to as a cotyledon - hence the name mono (one) cotyledonLeaves have parallel venation and are generally strap-like in appearanceFlowers have petals and floral parts in multiples of threeIn the stem, vascular bundles are scattered and absence of vascular cambium explains absence of secondary growthA pollen grain with one openingRoot system is generally fibrous, shallow and adventitiousStomata can be found on both epidermal layers of monocot leaves. This condition is called amphistomaticExamples of monocot plants are: (grasses) most ornamental turf lawns, (bamboo's) ornamental and wild bamboo's inlcuding sugar cane, (grain plants) rye, rice, wheat, maize (bulbous plants) such as lilies, agapanthus, clivia, orchid varieties, most palm tree varieties</span>
<span>It should be noted that Monocotyledonous plants make up one huge slice of the worlds cereal/ edible crops, the staple diet of literally Billions of people and animals! </span>
Dicotyledons:<span>Embryos have two seed leaves, referred to as cotyledons - hence the name di (two) cotyledon - although dicots now known as eudicots, most people still use the term "dicot"Leaves have branched venationFlowers have petals and floral parts in multiples of four or fiveIn the stem, the vascular tissue is arranged circularly and presence of vascular cambium explains ability to effect secondary growthA pollen grain with three openingsRoot system is generally branched, but taproot basedStomata can only be found in the lower epidermis. So, we describe it as hypostomatic conditionExamples of dicot plants include: (veg) tomatos, peppers, cabbage, beans, peas, (flowers) sunflowers, roses, daisies, violets, petunia, pansy (fruit) apples, pears, cherries, avocardo</span>
