R H Whittaker proposed the five kingdom classification in 1969 and named the kingdoms as Monera, Protista, Fungi, Plantae and Animalia.
 

A heterocyst is a differentiated cyanobacterial cell that carries out nitrogen fixation. 

They are photosynthetic autotrophs.

Eukaryotic flagella show 9+2 arrangement which is absent in prokaryotes.

 Herbivore dung supports a wide variety of coprophilous fungi. 

Monera is prokaryotic as they do not have a well-defined nucleus. All the organisms of this kingdom are prokaryotes. Complex structure was the basis of classification of organisms, many centuries ago. According to R.H. Whittaker's five kingdom classification, all the bacteria were placed under the Kingdom Monera. Monera is considered as the most primitive group of organisms. They include various types of bacteria and blue-green algae. Monerans are most abundant of all organisms, due to the versatility of their habitat. It is estimated that a single drop of water contains 50 billion bacteria.

Lichen is a symbiotic association between algae and fungi. Algal component is called phycobiont and fungal component is called mycobiont.

Protists are eukaryotic in nature.

Euglena is a green coloured, single celled organism which moves like animals. Some taxonomists considered it to be animals. Some taxonomists considered it a plant and included it in the plant kingdom on the basis of chlorophyll while others included it in animal kingdom alongwith the protozoans because of the locomotion by flagella.
