Reproductive Shoot Apex

Reproductive Shoot Apex (Floral Apex) The reproductive apex produces a flower or an inflorescence and replaces the vegetative apex. The flowering shoot is considered as homologous to the vegetative shoot. According to Gregoire, the reproductive meristem is structurally different from vegetative meristem. He suggested that reproductive apex consists of a meristematic Mantle and a Core. [Continue]

Plant Anatomy Theories

Plant Anatomy Theories Different theories about plant anatomy and different types of cells playing important role in proper functioning of plant, given by different scientists & botanists accordingly with passage of time are as follow: Apical Cell Theory: According to this theory, in pteridophytes one or more initials are recognized which are responsible for the [Continue]

Tissue Types And Tissue System

Tissue Types & Tissue System The tissues, i.e., complex of cells are of two types: Meristematic Tissues: It is a tissue composed of immature, not well differentiated cells which has the capacity of division. Meristems: The term Meristem is derived from a Greek word Meritos meaning Divisible. It emphasizes the cell division activity characteristic of [Continue]

Plant Anatomy – Internal Organization

Plant Anatomy Internal Organization The plant body is divided into stem, leaf and root. Evolutionary studies suggest that organization of oldest land plant was very simple resembling leafless and rootless Devonian plant, Rhvnia. If seed plants have evolved from these plants then the leaf, the stem and the root would be closely related phylogenetically, ontogcnelieally. [Continue]


STUDY OF MERISTEM The tissues in which the cells are undifferentiated and capable of division are called meristem.  The activity of meristem Causes growth in plant. Meristem adds new cells continuously. The apices of roots, shoots and their lateral branches have meristems at their tips. It increases length or the respective axis. Other meristems are [Continue]
