Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies. Internal fertilization is followed by mammals, birds, while external fertilization is supported by mostly aquatic animals and few amphibians. We all are aware of the word fertilization, which defines … [Read more...]

Difference Between Arteries and Veins

Arteries carry oxygenated blood away from the heart, these are the thick-walled muscular tube, while Veins carry deoxygenated blood towards the heart. Though both have the exception of the pulmonary artery and vein, as here the system get opposite and the pulmonary artery carries the deoxygenated blood, and pulmonary vein carries oxygenated blood. Among the two types of circulatory system - Open circulation and Closed circulation. In vertebrates, closed type of circulatory system is found, … [Read more...]

Ovum, also known as egg cell and is said to be the largest cell in the female body. On the contrary Sperm cells is the smallest cell in the male body. Egg cell and sperm cells differ in many ways, which can be their origin, nature, composition, and purpose for existence. Though both play an important role at the time of human reproduction process, where the … [Read more...]

Difference Between Bones and Cartilage

June 30, 2017 by Rachna C Leave a Comment

A bone is a hard connective tissue, while cartilage is soft connective tissue. Bones form the skeletal structure of the body, whereas cartilage is present in nose, ear, ribs, larynx, and joints and also act as a shock absorber in these joints. Bones protect against the mechanical damage and supports the movement of the body, provide shape to the body. And as cartilage being soft they are usually found along the respiratory tract, between the joints and in other flexible parts of the … [Read more...]

Difference Between Chordates and Non-Chordates

June 19, 2017 by Rachna C 5 Comments

The animal has a cord or backbone in their body structure are chordates. Contrary, Non-chordates are the animals without backbone or notochord, this the vital difference between chordates and non-chordates is that the. These animals belong to the different phyla of the animal kingdom. Also being same at the multicellular level, there is a lot of difference between patterns of organization of cells in this kingdom. Lower animals like coelenterates, sponges differ in cellular level of … [Read more...]

Difference Between Cold-blooded and Warm-blooded Animals

April 20, 2017 by Rachna C 1 Comment

Cold-blooded are the animals which cannot regulate their internal body temperature according to the required level and they keep on changing their temperature according to the changes in external environment temperature. Although Warm-blooded animals attempt to keep their internal body temperature maintained and does not change the same along with changes in external environment. For example, if it is colder outside, the body of Warm-blooded animals try to adapt according to the situation and … [Read more...]

Difference Between Invertebrates and Vertebrates
