    Study Notes

    Pharmaceutical Botany

    • Studies plants used for drug extraction to treat diseases in humans and animals.

    Key Branches of Pharmaceutical Botany

    • Pharmacognosy: Focuses on the collection, preservation, and classification of medicinal plants.
    • Pharmacology: Examines drug actions and their effects on living organisms.

    Specialized Fields in Botany

    • Phycology or Algalogy: Study of algae; includes diatomology (study of diatoms).
    • Mycology: Focuses on fungi; includes lichenology (study of lichens).
    • Microbiology: Studies microorganisms; includes bacteriology (study of bacteria) and virology (study of viruses).
    • Bryology: Examination of bryophytes, including moscology (study of mosses) and hepaticology (study of liverworts and hornworts).
    • Pteridology: Study of pteridophytes (ferns and their relatives).
    • Palynology: Investigation of pollen grains and spores.

    Differences Between Plants and Animals

    • Form and Structure: Plants exhibit variable forms; animals generally have fixed sizes.
    • Metabolism: Plants are autotrophic (photosynthesis); animals are heterotrophic (consume other organisms).
    • Reproduction: Plants produce spores; animals do not.
    • Nervous System: Plants lack a nervous system; animals possess a nervous system.

    Introduction to Botany

    • Derived from Greek terms meaning plant and to feed; initially focused on practical uses of plants.
    • Intellectual curiosity led to the establishment of botany as a scientific discipline.

    Fundamental Properties of Life

    • Growth and Reproduction: Organisms can grow and reproduce, exhibiting intussusception and extrinsic growth.
    • Ability to Respond: Organisms respond to environmental changes, such as light or temperature.
    • Metabolism: Includes cellular respiration (energy release) and photosynthesis (food synthesis).
    • Ability to Evolve and Adapt: Evolution evidenced by the fossil record reflects species' adaptation to their environment.

    Historical Figures in Botany

    • Gaspard Bauhin: Described around 6000 plant species.
    • Caesalpino: Proposed an extensive plant classification system.
    • Carolus Linnaeus: Known as the Father of Taxonomy; developed a sexual system of plant classification.
    • A.L. de Jussieu: Formulated phylogenetic classification systems.
    • Zacharias Jansen: Perfected the magnifying lens for plant anatomy.
    • Robert Hooke: Initiated studies in cytology.
    • Mathias Schleiden: Proposed the cell theory; cells as basic life units.

    Scope of Botanical Studies

    • Pure Botany: Intrinsic study of plant characteristics; includes:
      • Morphology: External and internal plant structures.
      • Taxonomy: Identification and classification of plants.
      • Physiology: Functional processes in plants; includes biochemistry and biophysics.
      • Ecology: Plant interactions with the environment.
      • Geography: Distribution of plants globally.
      • Paleobotany: Study of extinct plants through fossils.

    Economic or Applied Botany

    • Studies plants for commercial and practical values:
      • Agriculture: Food production, covering agronomy, pathology, genetics, and horticulture (including olericulture and pomology).
      • Forestry: Management of forest and timber plants; includes dendrology and wood technology.

    Experiment on Spontaneous Generation

    • Hypothesis: Rotten meat does not produce flies; only flies can reproduce.
    • Testing involved controlled jars to observe presence of flies and maggots.
    • Results confirmed only exposed meat attracted flies; sealed jars showed no signs of flies or maggots.
    • Conclusion: Disproving spontaneous generation; maggots arise from eggs laid by flies.
