Distinguish between unicellular and multicellular organisms
Answers
Answer:
organisms which are made up of only one cell or single cell is called unicellular like amoeba.
organisms which are made up of more than two cells are called multicellular organisms like human
Answer:
Unicellular organism
and Multicellular organisms
1. The structure of the unicellular is made up of a single cell.
1.The structure of the multicellular organisms is made up of numerous cells.
2. Amoeba, paramecium, yeast all are examples of unicellular organisms.
2. Few examples of multicellular organisms are human beings, plants, animals, birds, and insects.
3. The shape of the unicellular organism is irregular.
3. The multicellular organisms have a definite shape.
4. The unicellular organism has a simple body organization.
4.They have complex body organization.
5. In a unicellular organism, a single cell is responsible to carry the process of life
5.In a multicellular organism, different cells are specialized to perform different functions.
6. Unicellular organism includes both eukaryotes and prokaryotes.
6. Whereas, multicellular organisms only include eukaryotes.
7. The overall body cell of a unicellular organism is exposed to the environment.
7. In a multicellular organism, only the outer cells are exposed to the environment.
8. Division of labor, in a unicellular organism, is at organelle level
8. On the other hand, a division of labor, in a multicellular organism, is at cellular, organ system level and organs.
9. Usually, a lifespan is short.
9.A lifespan of a multicellular organism is long.
10. The unicellular organism is reproduced by asexual reproduction.
10.Multicellular organisms are reproduced by sexual reproduction.
11. In a unicellular organism, cell differentiation is absent.
11. Cell differentiation is obvious in a multicellular organism.
12. The unicellular organism is heterotrophs in nature.
12.Multicellular organisms are both heterotrophs and autotrophs in nature.
