single cell proteins

Single cell proteins are tiny organisms that can be used as a source of protein for humans and animals. They are made up of just one cell, which means they are very small and simple. These proteins can be grown in a lab or a factory using things like bacteria or yeast. One example of a single cell protein is spirulina, which is a type of algae that is rich in protein and other nutrients. Another example is Quorn, which is a meat substitute made from a fungus. Did you know that single cell proteins have been used in space exploration? Astronauts have eaten foods made from these proteins while on long missions in space. Think of single cell proteins like tiny Lego pieces that can be put together to make a big, strong building. Just like how you can build something great with just one Lego piece, you can get a lot of protein from just one cell.
