Study Notes
Mycology and Botany Specializations
- Mycology focuses on the biology of fungi, a diverse group critical for ecosystems and medicine.
- Pteridology is the study of ferns and related plants, essential for understanding plant evolution and diversity.
- Phycology concentrates on algae, vital for aquatic ecosystems and oxygen production.
Applied Botanical/Plant Sciences
- Agronomy applies crop and soil sciences to enhance the yield of field crops.
- Plant breeding aims to develop improved plant varieties with traits like disease resistance.
- Biotechnology involves gene manipulation to produce beneficial products using biological organisms.
- Economic botany studies how humans utilize plants, analyzing both harmful and beneficial species.
- Food science and technology focus on developing food products from various plant sources.
- Forestry encompasses forest management and the sustainable use of forest resources.
- Horticulture is the cultivation of ornamental plants, fruits, and vegetables.
- Natural resource management emphasizes responsible resource use and protection for societal benefit.
- Plant pathology investigates plant diseases to enhance agricultural productivity.
- Phytochemistry examines plant biochemistry and the chemical processes involved in plant life.
- Systematics studies the evolutionary relationships among plants, including their classification.
- Systems ecology uses mathematical models to understand plants' roles in ecosystems, like nutrient cycling.
- Taxonomy identifies, names, and classifies plants into organized categories.
Living vs Non-living Criteria
- Living organisms possess defined forms, coordinated cellular organization, and can grow and reproduce.
- Non-living entities do not exhibit cellular organization, do not metabolize, and lack the ability to reproduce.
Plants vs Animals
- Plant bodies exhibit variable forms while animal bodies are constant; plants have rigid cell walls made of cellulose.
- Plants manufacture food through photosynthesis, whereas animals rely on the consumption of plants or other animals.
- Plants respond more slowly to stimuli compared to animals, which possess a nervous system for faster reactions.
Historical Figures in Botany
- Theophrastus, often called the "Father of Botany," classified plants and authored significant botanical texts.
- Pedanius Dioscorides significantly influenced pharmacology with his work "De Materia Medica."
- Hieronymus Bock published "Herball," advancing plant classification and nomenclature.
- Otto Brunfels is recognized among the "Fathers of Botany" for his contributions to plant identification.
- Leonhart Fuchs authored "Notable Commentaries on the History of Plants," contributing to plant classification.
Plant Classification
- Approximately 350,000 plant species are recognized, underscoring the vast diversity of the plant kingdom.
- Taxonomy focuses on plant classification, historically based on growth habits but now prioritizes reproductive structures.
Plant Kingdom Classification
- Thallophytes (e.g., bacteria, fungi, algae) do not develop embryos, while Embryophytes (e.g., trees, flowers) do.
Structure of Eukaryotic Plant Cells
- Key components of living plant cells include the cell wall, protoplast (encloses organelles), and inclusions.
Cell Components
- Cell Wall: Composed mainly of cellulose; serves as a protective non-living structure.
- Protoplast: Living part of the cell, divided into cytoplasm and nucleus.
- Plasma Membrane: Selectively permeable, regulates entry and exit of substances.
Organelles and Their Functions
- Mitochondria: Sites of cellular respiration; contain double membranes with folded inner structures.
- Ribosomes: Involved in protein synthesis, visible only under electron microscopy.
- Golgi Bodies: Package and secrete cellular materials; structured in multilayered complexes.
- Lysosomes: Contain digestive enzymes for cellular waste disposal and recycling.
- Plastids: Include chloroplasts (photosynthesis), leucoplasts (food storage), and chromoplasts (pigment storage).
Nucleus and Its Components
- Nucleus: Control center for cell activities.
- Nuclear Membrane: Regulates material passage in and out of nucleus.
- Chromatin: Contains hereditary information visible during cell division.
- Nucleoli: Synthesize ribosomal RNA essential for ribosome formation.
Inclusions
- Non-protoplasmic structures such as vacuoles (storage of substances) and crystals (various functions) are present in plant cells.
