Aerobic Respiration

Aerobic respiration is the process by which complete oxidation of respiratory substrate occurs. In this case, respiratory substrate glucose breaks down in the presence of oxygen resulting in the end products of CO2 and H2O. Most of the cells perform the respiration through aerobic process. Aerobic respiration occurs by completing the series of chemical reactions. … Read more

Cilia and Flagella: Structure and Functions

image of Parts of flagellum

The hair-like extended portion of the cell surface bounded by the cell membrane and containing microtubules and responsible for cell motility are known as cilia and flagella. The cilia and flagella are widely distributed in both the animal and plant cells. Flagella (singular = flagellum) are complex filamentous, long, thread-like structures that extend from the … Read more

Mitosis: Definition, Stages of Mitosis and its Significance

image of Mitosis

The old cells divide to produce new cells. In this case, a single old cell divides into two cells and these two new cells again divide to produce four cells and so on. Generally, this process is known as cell division where a parent cell divides into two or more daughter cells. The capability of … Read more

Sixspine Butterfly Fish: Parachaetodon ocellatus

Sixspine butterfly fish is a very attractive fish which is also known as Ocellated Coralfish, Eye-spot Butterflyfish, Six-spined Butterfly-fish or Six-spined Coralfish. It has compressed, sub-rhomboidal body with prominent snout. Anterior portions of soft dorsal and anal fins are the highest. Lateral line ceases the opposite of the posterior fourth of the dorsal fin.  Systematic … Read more

Anaerobic Respiration and Its Application

Anaerobic respiration is the process by which incomplete oxidation of respiratory substrate takes place. In this case, it occurs in the absence of oxygen resulting the end products of ethyl alcohol and CO2 in plants and lactic acid (in animals) with very slight energy.  Anaerobic respiration is observed in certain bacteria, yeast and other fungi, … Read more
