Chlamydomonas and Amoeba are classified in kingdom protista according to Whittaker's classification system but by earlier classification system both these organisms are classified in different kingdoms (True/False)

Answer

To determine whether the statement "Chlamydomonas and Amoeba are classified in kingdom Protista according to Whittaker's classification system but by earlier classification system both these organisms are classified in different kingdoms" is true or false, we can follow these steps:

### Step 1: Understand Whittaker's Classification System
Whittaker's classification system divides living organisms into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. In this system, both Chlamydomonas and Amoeba are classified under the kingdom Protista.

### Step 2: Identify the Characteristics of Chlamydomonas and Amoeba
- **Chlamydomonas**: It is a unicellular green alga that can perform photosynthesis, thus it is autotrophic.
- **Amoeba**: It is a unicellular protozoan that is heterotrophic, meaning it obtains its food by consuming other organisms.

### Step 3: Review Earlier Classification Systems
In earlier classification systems, such as that proposed by Aristotle, organisms were classified primarily into two kingdoms: Plantae and Animalia.
- **Chlamydomonas** would be classified under Plantae because it is autotrophic (able to produce its own food).
- **Amoeba** would be classified under Animalia because it is heterotrophic (it consumes other organisms for food).

### Step 4: Compare Classifications
According to Whittaker's classification, both organisms are in the same kingdom (Protista). However, in earlier classification systems, they were placed in different kingdoms (Chlamydomonas in Plantae and Amoeba in Animalia).

### Conclusion
The statement is **True**. Chlamydomonas and Amoeba are classified in the kingdom Protista according to Whittaker's classification system, but by earlier classification systems, they are classified into different kingdoms.
