Why is it difficult to classify protists? Select three options.

There are many varying characteristics and exceptions to each type of protist.
They have been previously categorized based on what they are not.
They are all eukaryotes composed of one or more cells that contain nuclei.
There are no exceptions to the characteristics of each type of protist.
They are microscopic and therefore too small to study accurately.
Recent studies show that protists have not descended from one common ancestor.

Please help me, I have a bad grade in science so far : (

Scientists used to lump protists into a single kingdom, and they still use this classification for some purposes. However, science has largely recognized that the taxonomic grouping known as Kingdom Protista actually includes a wide range of organisms that are not particularly related.

The eukaryotic organism that does not belong to fungi, plants or animals is called protists. They generally are found in moist or aquatic places.

It is difficult to classify protists because:

Option A. There are many varying characteristics and exceptions to each type of protist.

Option B. They have been previously categorized based on what they are not.

Option F. Recent studies show that protists have not descended from one common ancestor.

The reasons can be explained as:

The diversity of the kingdom makes it difficult for the characterization of protists. They have various reproductive modes, body forms and can be colonial, multicellular or unicellular.

They can also act as a parasite or can live in a symbiotic relation. It was recently found that they did not descend from a common ancestor that makes the difference.

Therefore, options A, B and F are correct.
