Tree of Life Mind Map Structure

A tree of life mind map is a visual summary of how scientists classify living organisms. It starts with the broadest level, the three domains: Bacteria, Archaea and Eukarya. Each domain then divides into kingdoms, and kingdoms divide further into phyla, classes and species. Seeing these levels as branches makes the nested relationships easier to remember.

Domains: Bacteria, Archaea and Eukarya, the highest level of classification
Kingdoms: Animalia, Plantae, Fungi, Protista and the prokaryotic groups
Major phyla: examples of key groups within animal and plant kingdoms
Taxonomic ranks: order, family, genus and species from broad to specific
Evolutionary links: how common ancestry connects branches on the tree

Use the map to revise classification order, then check how each branch connects to the next level. A personalized version from your own notes helps you focus on what your course actually covers.

Tree of Life Questions

Answers on the biology topic and on building your own map.

What are the three domains of life?

The three domains are Bacteria, Archaea and Eukarya. Bacteria and Archaea are prokaryotic, meaning their cells lack a nucleus. Eukarya includes organisms whose cells have a nucleus and membrane-bound organelles, such as animals, plants and fungi.

How many kingdoms are in the tree of life?

Many classification systems use six kingdoms: Bacteria, Archaea, Protista, Fungi, Plantae and Animalia. Some older systems used five. Your course may follow a specific system, so check your textbook.

Which file types can I use to make my map?

You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image. You can also type a topic and let the AI build the map from it.

Can I turn the tree of life map into a quiz?

Yes. Once the map is built, you can turn it into a quiz to test yourself on the domains, kingdoms and groups. The same notes can also become flashcards. A free plan allows 5 creations a week.
