Solution:

Monera is the kingdom of all prokaryotes and includes bacteria, blue-green algae (cyanobacteria) and archaebacteria (a group of ancient bacteria). Protista includes unicellular and colonial eukaryotes; the important members are diatoms, dinoflagellates, euglenoids, moulds and protozoans. Fungi is the kingdom of multicellular or multinucleate heterophyllous and spore-producing eukaryotic organisms like Rhizopus mildews, mushroom etc. Kingdom Plantae includes all coloured multicellular photosynthetic organisms (plants).
