For unicellular organisms like bacteria, unicellular algae and amoeba, (A)____ is synonymous with ______(B)

Answer

To solve the question, we need to identify what A and B represent in the context of unicellular organisms like bacteria, unicellular algae, and amoeba.

1. **Understanding the Question**: The question states that for unicellular organisms, (A) is synonymous with (B). We need to determine what these terms are.

2. **Identifying Characteristics of Unicellular Organisms**: Unicellular organisms are characterized by their ability to reproduce and grow.

3. **Defining Reproduction in Unicellular Organisms**: In unicellular organisms, reproduction typically involves cell division, where one cell divides to form two new cells. This process increases the number of organisms.

4. **Defining Growth in Unicellular Organisms**: Growth in unicellular organisms can also be understood as the increase in size and mass of the single cell until it reaches a certain size, at which point it divides.

5. **Establishing the Synonym Relationship**: Since reproduction in unicellular organisms is essentially the process of one cell dividing to form two, and growth can be viewed as the preparation for this division, we can conclude that in this context, reproduction and growth are synonymous.

6. **Filling in the Blanks**: Therefore, we can fill in the blanks as follows:
- (A) = Reproduction
- (B) = Growth

So the complete statement would be: For unicellular organisms like bacteria, unicellular algae, and amoeba, (A) reproduction is synonymous with (B) growth.

### Final Answer:
For unicellular organisms like bacteria, unicellular algae, and amoeba, (A) reproduction is synonymous with (B) growth.
