During the secondary growth in both stem and root, the peripheral tissues like epidermis, hypodermis and cortex are replaced by a new secondary tissue called the Periderm (bark). The periderm composed of three components: (1) Phellogen, (2) Phellem and (3) Phelloderm. The current post discusses the Similarities and Differences between […]

Primary vs Secondary Meristem Meristems are a group of plant cells that remain in a continuous state of division. The meristematic cells continuously produce new cells through the life of the plant. In previous posts, we have discussed the Characteristics of Meristematic Cells, Classification of Meristems and Difference between Meristematic […]

Stem: Stem is the part of the plant which lies above the surface of the soil. It arises from the plumule of the embryo. Stem shows positively phototropic and negatively geotropic growth. Stem possess nodes and internodes. Branches, leaf, flower bud and bracts are developed from nodes. Root: Root is […]

Shoot Apex vs Root Apex Apex is the growing terminal portions of the stem and roots in plants. The apical portion of the stem is called ‘Shoot Apex’ and that of the root is called ‘Root Apex’. The apex portions of both stem and root possess a meristematic tissue called […]

Prokaryotic vs Eukaryotic Chromosome Prokaryotes and Eukaryotes are the two major domains of living organisms. This classification is on the basis of the features of their cellular features primarily the nature of membrane bounded organelles and organization of the genetic materials. Both prokaryotes and eukaryotes contain the genetic materials which […]
