Dicot and monocot leaves shows differences on their leaves mostly in the arrangement of veins explain it.

Read the following statements and find out the incorrect statement. a. Embryo development precedes endosperm development. b. Though the seeds differs greatly the early stages of embryo development (embrogeny) are similar in both monocotyledons and dicotyledons. c. A typical dicotyledonous embryo consists of an embryonal axis and two cotyledons. d. Endosperm may either be completely consumed by the developing embryo (e.g., castor and coconut) before seed maturation or it may persist in the mature seed (e.g., wheat, rice, maize, pea, groundnut and beans). e. The coconut water from tender coconut is cellular endosperm and the surrounding while kernel is the nuclear endosperm.
