Kingdoms of life branch off? Is Protista at top, then Monera and Fungi, Plantae, and Animalia branch of Mo?

Sorry, couldn't word it properly in my question.


So, I need to glue the kingdoms as they branch off each other.


My friend told me that Protista is on it's own at the top and then there's Monera, and the Animalia, Plantae, and Fungi branch off the Monera


Is that right?Kingdoms of life branch off? Is Protista at top, then Monera and Fungi, Plantae, and Animalia branch of Mo?
No, that's totally wrong. Using the 5 kingdom system, Monera would be on a branch on its own. The Monerans, or prokaryotes, are single celled organisms whose DNA is not contained in a membrane-bound nucleus. In all of the other kingdoms cells contain a nucleus surrounded by its own membrane which holds the entire genome (all of the DNA).





You could represent Monera at the bottom of the tree with all other kingdoms coming up from it, sort of like this:

Here's another example:

This one shows the split between Archaea and Eubacteria, but since your teacher isn't having you learn that I would just ignore it for now. Just know that modern cellular and genetic analysis tells us that all prokaryotes are not as closely related as we once thought and that there is huge diversity among them. Under the old 5 kingdom system, Archaea and Bacteria are combined under Monera.





Here is another one that is sort of similar:

It shows the more modern three domain system (Archaea, Bacteria, Eukarya) but also divides them up into kingdoms. Again it separates the monerans but you could combine them in your depiction:

Below are some other examples. I hope these give you some ideas. You can see that there are several different ways to represent the same idea. Some are more complex and detailed than others, but you can see the basic idea.
