Key Difference – Evolution vs. Speciation The terms evolution and speciation have very close links, although they have completely different definitions in the natural and social sciences. According to Darwin, evolution occurs mainly through the natural selection by which one species evolves with the greater inherited characteristics that make them well adapted its changing environment. However, […]
Difference Between Pili and Flagella
Key Difference – Pili vs. Flagella Pili and flagella are two types of extracellular filaments, which are attached to the cellular membrane of most of the prokaryotes including bacteria and archaea. Pili and flagella are different from one another. A key difference that can be identified between the two stems from the function of these two […]
Difference Between Thallophyta and Bryophyta
Key Difference – Thallophyta vs Bryophyta According to the earliest classification of the plant kingdom, there were two sub-kingdoms; Cryptogamae (seedless plants) and Phanerogamae (seed-bearing plants). The sub-kingdom Cryptogamae is further divided into three divisions, namely; Thallophyta, Bryophyta, and Pteridophyta. According to this classification, both Thallophyta and Bryophyta include very primitive plants with no […]
Difference Between Primordial Follicle and Primary Follicle
Key Difference – Primordial Follicle vs Primary Follicle It is important to know about the process of folliculogenesis in order to understand the difference between Primordial Follicle and Primary Follicle; hence, we will first look at this process. The human ovaries are located behind and below the fallopian tube, and have two principle functions; […]
Difference Between Apical and Lateral Meristems
Key Difference – Apical vs Lateral Meristems Let us first understand what a meristem is, before looking at the differences between apical and lateral meristems. Meristem is a unique plant tissue made of cells that are not fully differentiated and capable of dividing continuously to produce new plant tissues. In addition, these cells possess […]
Difference Between Ingestion and Egestion
Key Difference – Ingestion vs Egestion Ingestion and egestion are two essential processes that take place in all organisms though there exists a difference between them based on their functions. In multicellular animals, these processes occur in the gastrointestinal tract whereas in unicellular organism they occur through cellular membranes. Food undergoes a series of […]
Difference Between Grana and Stroma
Key Difference – Grana vs Stroma Since Grana and Stroma are two unique structures of Chloroplasts, it is important to understand what is a chloroplast, before looking at the differences between grana and stroma. Chloroplasts are categorized under plastids, which occur as spherical or disc-like bodies in the cytoplasm of eukaryotic plant cells. The […]
Difference Between Monera and Protista
Key Difference – Monera vs Protista Monera and Protista are two kingdoms of living organisms that represent the unicellular organisms though there exists a difference between them based on the cell structure and organization. All living organisms are classified into five kingdoms based on their complexity of the cell structure, body organization, modes of […]
Difference Between NK Cells and NKT Cells
The key difference between NK cells and NKT cells is that NK cells are not antigen-specific receptors, while NKT cells are antigen-specific receptors. The immunity system is the body’s main system that can produce defensive action against invading pathogens and microbes. There are two types of immunity: innate immunity and adaptive immunity. Innate immunity produces […]
Difference Between Centriole and Centrosome
Key Difference – Centriole vs Centrosome Centriole and centrosome are both components of Eukaryotic cells, which are adapted to carry many different cellular functions though there are exists a difference between them based on their structure and functional capabilities. The structural units of these two components are microtubules. Microtubules are composed of protein subunits […]
