Give at least 10 branches of science?
These are the branches of plant sciences:1.Morphology is the branch of science deals with Description of different plant organs (two parts) (Fundamental prerequisite for classification of plants)2. External Morphology deals with Description of external characters of plant organs3. Internal Morphology deals with Internal structure of different plant organs (2 branches)4. Histology deals with Different tissues present in the plant body.5. Anatomy deals with Gross internal details of the plant organs.6. Cytology Structure and functions of cell and cell organelles and their multiplication.7. Embryology deals with Development of male and female gametophytes, formation of gametes, process offertilization, development of embryo, endosperm and seed. P. Maheswari made significant contributions to Embryology8. Palynology deals with All aspects of microspores or pollen grains including their structure and development.9. Plant Taxonomy Identification, Nomenclature and classification of plants into related groups based on the information obtained from other fields of Botany.10. Plant Physiology deals with Different vital activities of plants like absorption of water and minerals, photosynthesis, transpiration, Nitrogen metabolism, growth etc.11. Plant Ecology deals with Reciprocal relationship between the plants and the environment12. Palaeobotany deals with Fossil plants. (This study helps in understanding the process of evolution)13. Genetics deals with All aspects related to genes such as structure, synthesis, inheritance, mutations etc.14. Phytogeography deals with Distribution of plants in different parts of the globe during past and present.15. Phycology deals with all aspects related to algae which are Chlorophyllous and autotrophic thallophytes (algae)16. Mycology deals with all aspects of fungi which are Nonchlorophyllous heterotrophic thallophytes (fungi)17. Lichenology deals with Lichens special group of plants in which an algal member and a fungal member live together as symbionts. (Lichens mostly grow on rocks)18. Bryology deals with study of bryophytes. These are the first Embryophytes of plant kingdom. Mostly grown on damp and shady places.19. Pteridology deals with the study of Pteridophytes - first vascular plants, known as vascular cryptogams.20. Taxonomy: It is the study of identification, nomenclature and classification of animals
