why are proteins synthesied from spirulina called single cell capsule proteins ?

Explanation

### Step-by-Step Solution:

1. **Understanding Spirulina**: Spirulina is a type of cyanobacteria, often referred to as blue-green algae. It is known for being a rich source of protein and other nutrients.

2. **Protein Content**: Spirulina contains a high percentage of protein, making it a valuable food source for both humans and animals. It is particularly useful for individuals who may have dietary restrictions or allergies to traditional protein sources like pulses.

3. **Unicellular Organism**: Spirulina is classified as a unicellular organism, meaning it consists of a single cell. This characteristic is crucial in understanding why the proteins derived from it are termed "single cell capsule proteins."
