The parts of the plant body of the angiosperms are divided into two distinct systems: therootandshoot. In terrestrial plants, the root system is the plant organ that is normally underground (descending) while the shoot system is above ground (ascending). The root system consists of the primary...
This level of organization allows an organism to perform all of its functions. RESPONSE TO STIMULI: All organisms are affected by their environment and other living organisms. This sensitivity allows them to survive in their environment. A good example of this is the plantMimosa pudica. This plan...
The reproductive cycle in angiosperms can be traced from before the shedding of pollen. The microspores begin their development of male gametophytes, which involves formation of a smallgenerativecell and atube cell. The generative cell may divide to form two sperm cells before the pollen grain (...
Here we review the biological functions conferred by various classes of plant specialized metabolites in the context of the interaction of plants with their surrounding environment. To achieve optimal multifunctionality of diverse specialized metabolic processes, plants use various adaptive mechanisms at ...

The plant height and organ size is controlled by brassinosteroids, auxins, and gibberellins.1, 2 The triazole-based PGRs directly interfere with the biosynthesis of brassinosteroid, ABA, and gibberellic acid (GA) in plants (Figures 1 and 2). Their interference with the enzymes of GA biosynthesis...
Plant Structures Leaves, Roots and Stems Objectives Describe the structure and function of leaves Describe the structure and function of roots Describe the function of stems Classifying Plants Plants belong to Kingdom ___ Within this kingdom plants can be divided into two major groups ___ and ...
Plants are maintaining at least one copy of MIPS gene in a core catalytic domain [1] though their expression and function are not constant throughout the plant kingdom. Furthermore, several plant species contain multiple MIPS genes, possibly to respond in specific physiological requirement [8,15...
Regulating gene expression and maintaining genome stability are crucial functions, with each approach playing a distinct and essential role. Figure 2. Plant epigenetic modifications in response to stress management during growth and development. 2.1. DNA Methylation (DM) Epigenetic modification through ...
Plants are constantly exposed to both biotic and abiotic stresses which limit their growth and development and reduce productivity. In order to tolerate them, plants initiate a multitude of stress-specific responses which modulate different physiological, molecular and cellular mechanisms. However, many ...
