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 [...]
In this article we will discuss about the structure and life history of monocystis. Structure of Monocystis: The adult organism or the Trophozoite has the following features: 1. Body spindle-shaped and flat and covered by a thin layer of cuticle. The anterior end is broader and the posterior end is narrower. 2. The cytoplasm is divisible into a thin outer [...]
The following points highlight the top four modes of nutrition in protozoa. The modes are: 1. Holozoic 2. Holophytic (Holos = Whole + Phyton = Plant Origin) or Autotrophic (Photosynthesis) 3. Saprophytic (Sapros = Rotten) or Saprozoic 4. Parasitic. Mode # 1. Holozoic: (holos = whole + zoon = animal). Most of the free-living protozoon's depend on engulfing the whole [...]
