- Studies the functions and processes of plants (photosynthesis, respiration, nutrient uptake).
-
Plant Ecology
- Examines the relationships between plants and their environments, including plant communities and ecosystems.
-
Plant Taxonomy
- The classification and naming of plants based on shared characteristics and evolutionary relationships.
-
Plant Anatomy
- Investigates the internal structure of plants, including tissues and organ systems (roots, stems, leaves).

Botany's Impact
- Provides food, medicines, shelter, and fibers contributing to overall industrial and ecological value.
Unifying Themes of Life
- All living organisms, unicellular or multicellular, exhibit connections and interactions with their environment.
Metabolism
- All organisms utilize energy; metabolism embodies the chemical processes sustaining life.
Homeostasis
- Living organisms maintain internal stability despite external changes, utilizing self-regulatory processes.
Reproduction
- All living things reproduce either sexually or asexually, fulfilling the purpose of species continuation.
Heredity
- Inherited traits stem from DNA, an essential molecule in genetic replication.
Distinct Characteristics of Plants
- Multicellular eukaryotes capable of photosynthesis (autotrophs).
- Presence of cellulose in cell walls.
- Alternation of generations: two adult forms, one producing spores and the other gametes (sperm or eggs).
Classification of Living Organisms
- Carl Von Linné introduced binomial nomenclature and established two kingdoms of life.
Six Kingdoms of Living Things
- Plantae
- Animalia
- Fungi
- Protista
- Eubacteria
- Archaebacteria
Kingdom Plantae
- Eukaryotic, multicellular organisms that predominantly use autotrophic nutrition, including mosses, ferns, conifers, and flowering plants.
Levels of Biological Organization
- Organismal, cellular, and ecological hierarchy exist within the study of botany.
Scientific Method
- Science encompasses a systematic approach for knowledge building, involving testable explanations and predictions about natural phenomena.
