DENDROLOGY

Detailed explanation-1: -Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

Detailed explanation-2: -As with all eukaryotic cells, protists contain membrane-bound nuclei and endomembrane systems, as well as numerous organelles.

Detailed explanation-3: -Some organisms have characteristics which do not qualify them to fit neatly into either kingdom. For instance, funguses and most bacteria do not photosynthesize and most of them lack a means of controlled locomotion. Some organisms have attributes of both plants and animals.
