Detailed explanation-1: -Cotyledon refers to the ‘first seed leaf’, present in the embryo. If it is a single seed leaf, then it is categorised as monocots and if it is a pair of leaves then it is categorised as dicots.
Detailed explanation-2: -Monocots have only one seed leaf, flower petals in threes and parallel veined leaves. Dicots have two seed leaves, flower petals in fours or fives and complex leaves with veins.
Detailed explanation-3: -Historically, plants are classified into two categories based on the number of cotyledons or embryonic leaves. Therefore, the term “monocot” refers to the flowering plants that contain only one cotyledon. Likewise, the term “dicot” refers to flowering plants having two cotyledons.
Detailed explanation-4: -Vascular plants are further divided into seedless and seed plants. Seed plants called gymnosperms produce seeds in cones. Seed plants called angiosperms produce seeds in the ovaries of flowers.
