BOTANY ORIGINS
efforts to identify poisonous, medicinal and edible plants
IMPORTANCE OF BOTANY
Aid food production
Understand life process
Create Medicine
Understand environmental changes
HOW BOTANY AIDS IN FOOD PRODUCTION
Enhance yields through plant breeding
Study weeds to reduce impact
ETHNOBOTANY
the study of Relationship btwn pple and plants
Limitations of classification
Rarely possible to construct with certainly past evolutionary pathway

TAXONOMY
Deals with classification nomenclature and identification
Classification
Ordering plants according to similarities
Types of classification
Artificial
Natural
Phylogenetic
ARTIFICIAL CLASSIFICATION
based on observable features
It’s easy- adv
Related plants may be separated no use of evolution relationship-dis
Natural classification
Sun of total characteristics
PHYLOGENETIC CLASSIFICATION
According to evolutionary sequence and genetic relationship
