Chapter 40.2, Problem 3LO
Summary Introduction
To explain: The relationship between floral meristem identify genes and floral organ identify genes.
Introduction: The plants are the multicellular eukaryotic organism in the kingdom Plantae. It is characterised by photosynthetic nutrition, a process through which it synthesis carbohydrates, essential unlimited growth at localised region, presence of cellulose in their cell wall and absence of locomotory organs.
