Characteristics of Protozoa
Habitat:
They live in damp, watery places, moist soil and in decaying matter of animals and plants.
Structure:
They are composed of only one cell. However they perform all the life activities e.g. intake of food, respiration and reproduction etc.
Mode of Life:
- i) Mostly they live singly.
- ii) Some times they form colonies.
Harmful Protozoa:
- i) Amoeba causes dysentery.
- ii) Plasmodium causes malaria.
Beneficial Protozoa:
Many protozoa are useful to man because they feed on harmful protozoa e.g. amoeba.
Shelled Protozoa:
Some protozoa live in sea. They have a calcium shell around them for protection. Hence they are called shelled protozoa.
Examples: – Their examples are amoeba, plasmodium and paramecium etc.
Also, living on a scholarship, a student cannot fully provide himself with food and other necessary things, so you have to either study where these are available (often, not where you want), or even postpone the idea of education until better times. Distance education allows everyone to find the profession of their dreams, regardless of the remoteness of the university. At the same time, there is an opportunity to work and pay for tuition independently.
