Plant identification taxonomy key characters

Plant taxonomic keys are important for plant identification for students and budding taxonomists. The PPT gives a brief insight into few basic identification plant characters

26. IDENTIFICATION AND CLASSIFICATION FOR PLANT
FAMILIES
Plantidentificationimplies assigning a plant to a
particulartaxonomicgroup.
It involves identification of certain characteristic features of that particular
family or plant which would help in giving right taxonomic position.
It mainly involves using morphological features.
Classification is important because it allows scientists to identify, group, and
properly name organisms via a standardized system (Linnaeus Taxonomy);
based on similarities found in the organisms DNA/RNA (genetics),
Adaptations (Evolution), and Embryonic development (Embryology) to
other known organisms to better study and understand the new organism as a
whole.
