Carl Linnaeus. Carl Linnaeus, also known as Carl von Linné or Carolus Linnaeus, is often called the Father of Taxonomy. His system for naming, ranking, and classifying organisms is still in wide use today (with many changes

Artificial classification is based on a few morphological characters of organisms like flower shape, stem type and types of seeds.

First phylogenetic system of classification was given by Engler and Prantl which was based on evolutionary relationship of the organisms. Those evolved earlier are classified first and newly evolved later on.

Merriam-Webster defines chemotaxonomy as the method of biological classification based on similarities in the structure of certain compounds among the organisms being classified.

Two organisms morphologically similar to each other are classified on the basis of chemotaxonomy.

Prokaryotic organisms generally do not reproduce by sexual reproduction in favorable conditions. The most common method of reproduction is asexual.

Cladogram is arranging organism on the basis of their shared similar or derived characters that differ from ancestral character. It is an important tools of taxonomical studies.

Unicellular organisms are made of only one cell and there is absence of tissue differentiation. All unicellular algae and fungi are separated from other organisms on this basis.

Prokaryotes differ from Eukaryotes in absence of nuclear membrane and membrane bounded organelles like mitochondria,Golgi bodies etc.

Cytotaxonomy is the branch of biology dealing with the relationships and classification of organisms using comparative studies of chromosomes.

Plant cell have cell wall made up of cellulose and chloroplast that contain chlorophyll for photosynthesis. Animal cell lacks both cell wall and chloroplast.
