Single-celled organisms are called Unicellular.
Explanation:To provide a detailed solution, let's break down the question and answer choices:
1.
Question: - The question states that single-celled organisms are being referred to.
2.
Answer Choices: - The answer choices are as follows:
- A: Unicellular
- B: Multicellular
- C: Both of these
- D: None of these
3.
Explanation: - Single-celled organisms consist of only one cell, which means they are composed of a single unit of life.
- The term "Unicellular" accurately describes these organisms, as it literally means "consisting of a single cell."
- Multicellular organisms, on the other hand, are composed of multiple cells, meaning they are made up of more than one unit of life.
- The answer choice B, "Multicellular," is incorrect because it refers to organisms that have multiple cells, which contradicts the question's focus on single-celled organisms.
- The answer choices C and D are also incorrect because they do not accurately describe single-celled organisms.
Therefore, the correct answer is A: Unicellular, as it accurately describes single-celled organisms.
