Question

Algae are plant microorganisms and protozoa are animal like microorganisms.explain

Answer 1

Protozoa are unicellular animal-like organisms. Paramecium and amoeba are protozoa, rpthey are found in stagnant water, ponds, soil, oceans, and in animal faeces. They depend on other organisms for food. Some feed on other protozoa and bacteria. Some parasites.

Answer 2

A microorganism is a living thing that is too small to be seen with the naked eye. Examples of microorganisms include bacteria, archaea, algae, protozoa, and microscopic animals such as the dust mite.

These microorganisms have been often under-appreciated and under-studied. Indeed, until Anton von Leeuwenhoek invented the microscope, we did not know they existed! Until that time, it was thought that phenomena such as illness and food spoilage were caused by “vapors” or “spontaneous generation.”

Though some microscopic fungi can infect humans just like bacteria or protozoa, there’s one microscopic fungus that most humans like a lot: yeast!

*Algae *

Microscopic algae were once thought to be plants, but recent studies have shown that algae don’t fit into the plant family. Instead, these single-celled photosynthetic organisms are thought to be relatives of the lineage that led to land plants.

Throughout history, algae have been important photosynthesizers. They likely evolved before land plants did, and helped to pump oxygen into Earth’s atmosphere along with their ancestors, the cyanobacteria.

Today algae can both help and hurt humans – some species clean water and produce oxygen, while others produce dangerous toxins that can end up in our seafood and drinking water.
