DENDROLOGY

Detailed explanation-1: -Angiosperms are classified into dicotyledons (dicots) and monocotyledons (monocots). This distinction is mainly based on the number of cotyledons present in the seed’s embryo. Dicots have two cotyledons. On the other hand, monocots have only one cotyledon.

Detailed explanation-2: -The correct option is C scutellum. Monocot embryo consists only one cotyledon. In grass family, the single cotyledon is called scutellum and is situated towards one side of the embryonal axis.

Detailed explanation-3: -Monocots contain a single cotyledon and have veins that run parallel to the length of their leaves; their flowers are arranged in three to six-fold symmetry. Dicots have flowers arranged in whorls, two cotyledons, and a vein arrangement that forms networks within their leaves.

Detailed explanation-4: -Angiosperms (flowering plants) whose embryos have a single cotyledon are grouped as monocots, or monocotyledonous plants; most embryos with two cotyledons are grouped as eudicots, or eudicotyledonous plants.
