In this article we will discuss about the process of locomotion in animals with the help of suitable diagrams. Locomotion involves change of place. It requires a means for support, development of a thrust against surrounding medium and stability. Some sort of skeleton, within (endoskeleton) or outside (exoskeleton) the body is present in most animals. It supports the animal and [...]
In this article we will discuss about the four main types of locomotion in protozoa. The types are: 1. Pseudopodial Movement 2. Flagellate Movement 3. Ciliary Movement 4. Peristaltic Movement. Type # 1. Pseudopodial Movement: Some protozoon's move with the help of pseudopodia. Pseudopodia are blunt, fingerlike temporary protrusions of the cytoplasm. These may be variously shaped. Large numbers of [...]
Locomotion is a characteristic and fundamental attribute of all forms of animals. Unicellular animals swim by cilia or flagella, crawl about with pseudopodia, make withdrawal movements on a stalk that coils up like a stretched spring, or glide along without apparent deformation in shape. Multicellular animals are characterized by the development of muscles—the specialized contractile tissues unique to the animal [...]
