Botany - Fields of Study (Concise)
Morphology
External Morphology: study and description of external characters of plant organs (root, stem, leaf, flower, fruit, seed)
Internal Morphology: study of internal structure of plant organs
Histology: study of tissues
Anatomy: study of gross internal details of plant organs (root, stem, leaf, flower, etc.)
Cytology (Cell Biology)
Structure and functions of cell and cell organelles and their multiplication
Embryology
Development of male and female gametophytes, formation of gametes, fertilization, development of embryo, endosperm and seed
Palynology
Study of development, structure, and aspects related to microspores or pollen grains
Plant Taxonomy
Identification, nomenclature and classification of plants into related groups based on information from Botany
Plant Physiology
Study of vital activities of plants: absorption of water and minerals, photosynthesis, respiration, nitrogen metabolism, growth, etc.
Plant Ecology
Study of reciprocal relationship between plants and the environment in which they live
Palaeobotany
Study of fossil plants; helps understand the course of evolution in plants
Genetics
Genes: structure, synthesis, inheritance, mutations, etc.
Phytogeography
Study of distribution of plants in different parts of the globe during past and present periods
Phycology
Study of all aspects related to algae (chlorophyllous and autotrophic thallophytes)
Mycology
Study of fungi (non-chlorophyllous, heterotrophic thallophytes)
Lichenology
Study of lichens (algal and fungal members live together as symbionts); mostly grow on rocks
Bryology
Study of bryophytes
Pteridology
Study of pteridophytes (the first vascular plants; called ‘Vascular Cryptogams’)
Microbiology
Study of all microorganisms: viruses, bacteria, algae, fungi, protozoans, etc.
Bacteriology
Study of bacteria
Virology
Study of viruses
Pomology
Study of fruits and fruit-yielding plants
Anthology
Study of flowers
Agrostology
Study of grasses or lawns
Dendrology or Xylology
Study of shrubs and trees
Dendrochronology
Determination of age of trees by counting annual rings
Phenology
Study of seasonal changes in plants
Xylotomy
Study of wood or xylem vessels
