Chloralla and spirulina which are grown to harvest SCP are

Options

A. Unicellular green alga and filamentous blue green alga respectively
B. Filamentous blue green alga and unicellular green alga respectively
C. Baker's Yeast and Torula yeast respectively
D. Filamentous fungus and unicellular fungus respectively

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
- The question asks about Chlorella and Spirulina, specifically what type of organisms they are that are grown to harvest Single Cell Protein (SCP).

2. **Defining Single Cell Protein (SCP):**
- Single Cell Protein (SCP) refers to protein extracted from single-celled organisms, which can include bacteria, yeast, fungi, and algae. SCP is a rich source of protein and is used to supplement diets in humans and animals.

3. **Identifying Chlorella:**
- Chlorella is a type of green algae. It is unicellular, meaning it consists of a single cell. Chlorella is known for its high protein content and nutritional value.

4. **Identifying Spirulina:**
- Spirulina is classified as a blue-green algae (also known as cyanobacteria). It is filamentous, meaning it forms long, thread-like structures. Spirulina is also rich in protein and other nutrients.

5. **Analyzing the Options:**
- The options provided in the question include:
- A) Unicellular green algae and filamentous blue algae
- B) Filamentous blue algae, blue-green algae, and unicellular green algae
- C) Bakers yeast and Chlorella yeast
- D) Filamentous fungus and unicellular fungus
- Based on the definitions, Chlorella fits as a unicellular green algae, and Spirulina fits as a filamentous blue algae.

6. **Selecting the Correct Answer:**
- The correct answer is A) Unicellular green algae and filamentous blue algae, as it accurately describes Chlorella and Spirulina.

**Final Answer:**
Chlorella is a unicellular green algae, and Spirulina is a filamentous blue algae. Therefore, the correct answer is A) Unicellular green algae and filamentous blue algae.
