What else can I help you with?
Why are unicellular organisms such as euglena and paramecium restricted to being microscopic in size?
This is because of the surface area compared to the volume area Eg. A small size : large surface area to a small volume. Or the movement of required particles would take to long to sustain life if the cell is to big.
What are some names of protozoans?
Single-celled, animal-like, eukaryotic organisms of the kingdom Protista. Protozoans can occur wherever moisture exists. There are many parasites and commensals of plants and animals, as well as free-living species. They cause a number of diseases, such as African sleeping sickness, malaria, and dysentery. They are an economically and scientifically important group. It is thought that the organisms of the kingdom Animalia evolved from ancestors which were protozoans.
