Activity #1
Botany is a natural science concerned with the study of plants. The main branches of botany (also referred to as "Plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for economic benefit in horticulture, agriculture and forestry and organismal topics which focus on plant groups such as algae, mosses or flowering plants.

Core topics
Cytology — cell structure, chromosome number
Epigenetics — Control of gene expression
Paleobotany — Study of fossil plants and plant evolution
Palynology — Pollen and spores
Plant biochemistry — Chemical processes of primary and secondary metabolism
Phenology — timing of germination, flowering and fruiting
Phytochemistry — Plant secondary chemistry and chemical processes
Phytogeography — Plant Biogeography, the study of plant distributions
Phytosociology — Plant communities and interactions
Plant anatomy — Structure of plant cells and tissues
Plant ecology — Role and function of plants in the environment
Plant evolutionary developmental biology — Plant development from an evolutionary perspective
Plant genetics — Genetic inheritance in plants
Plant morphology — Structure of plants
Plant physiology — Life functions of plants
