Study Notes
Botany Overview
- Also referred to as Plant Biology; studies origin, diversity, structure, internal processes of plants, and their interactions with organisms and the environment.
Disciplines of Botany
- Plant Molecular Biology: Examines biological molecules' structures and functions.
- Plant Biochemistry: Focuses on chemical interactions within plants and the chemicals produced.
- Plant Cell Biology: Studies plant cell structures, functions, and life processes.
- Plant Anatomy: Investigates microscopic structures like cells and tissues.
- Plant Morphology: Involves the structure and evolution of plant parts.
- Plant Physiology: Studies processes like photosynthesis and mineral nutrition to understand plant functions.
- Plant Genetics: Covers hereditary traits and variations in plants.
- Plant Ecology: Explores interrelationships among plants and their environments.
- Plant Systematics: Focuses on the evolutionary relationships among different plant groups.
- Plant Taxonomy: Describes, names, and classifies plants.
- Ethnobotany: Studies social groups' botanical knowledge and use of local plants.
- Paleobotany: Examines the biology and evolution of ancient plants.
Applied Plant Biology
- Agronomy: Involves field crops and soil management.
- Horticulture: Focuses on ornamental and vegetable crops.
- Forestry: Covers forest conservation and products.
- Economic Botany: Studies plants with commercial importance.
Life and Growth in Organisms
- Organisms exhibit order and organization, stemming from one or more cells.
- Growth and development are directed by genetic coding, ensuring offspring resemble parents.
- Reproduction ensures genetic material is passed to new individuals, with two types: asexual (no gametes) and sexual (utilizes gametes).
Three Domain System & Six Kingdoms
- Life classified into three domains, consisting of six kingdoms:
- Animalia
- Plantae
- Fungi
- Protista
- Eubacteria
- Archaebacteria
Plant Lifecycle
- Features both sporophyte (diploid) and gametophyte (haploid) generations, alternation of generations being fundamental.
- Fertilization leads to diploid zygotes which undergo mitosis to create sporophytes, producing spores through meiosis.
Bryophytes
- Small, spore-bearing plants commonly found in moist areas.
- Structure is simplistic, generally lacking vascular tissues (xylem and phloem).
- Depend on water for reproduction.
Evolution of Land Plants
- Land plants (Embryophytes) retain and nourish embryos, adapted for terrestrial life.
- Include various phyla: Bryophyta, Hepatophyta, Anthocerophyta, and others.
Seedless Vascular Plants
- Contain vascular tissue but do not produce flowers or seeds.
- Notable groups include club mosses, horsetails, whisk ferns, and ferns.
Gymnosperms
- Have "naked seeds" not enclosed in ovaries; commonly bear seeds in cones.
- Largest gymnosperm group includes conifers, distinguished by size contributing to their success.
Notable Gymnosperms
- Coast Redwoods: Over 100 meters tall.
- Giant Redwoods: Exceed 26 meters in circumference.
- Bristlecone Pines: Can live up to 4900 years.
Other Plant Groups
- Cycads: Thick-leaved plants often confused with ferns.
- Ginkgo biloba: A single living species known for its fan-shaped leaves.
- Gnetophyta: Includes Gnetum, Ephedra, and Welwitschia mirabilis; adapted to arid conditions.
Angiosperms
- The most diverse and recently evolved plant group, categorized in Magnoliophyta or Anthophyta.
- Key evolutionary adaptations include flowers and fruits for reproduction and dispersal.
