Study Notes
Plant Growth and Development
- Plant growth refers to the process of increasing in size and developing new structures.
- Key factors influencing plant growth include genetics, environment, and available resources.
Importance of Water to Plants
- Water is essential for photosynthesis, nutrient transport, and maintaining cell turgor pressure.
- It acts as a solvent for biochemical reactions and helps in temperature regulation within the plant.
Transport System in Plants
- Plants utilize a specialized transport system consisting of xylem and phloem for nutrient and water distribution.
- Xylem is responsible for transporting water and minerals from the roots to other parts of the plant.
- Phloem transports organic compounds, particularly sugars produced through photosynthesis, to areas where energy is required.
Plant Nutrition
- Botanists identify 17 essential elements necessary for plant nutrition, including nitrogen, phosphorus, and potassium.
- These elements play various roles in growth, development, and metabolism of plants.
Plant Hormones, Responses, and Feedback Mechanisms
- Plant hormones regulate growth and responses to environmental stimuli.
- Key hormones include auxins (growth promoters), gibberellins, cytokinins, abscisic acid (growth inhibitors), and ethylene.
- Hormonal balances guide plants in adapting to changing conditions.
Reproduction and Modern Biotechnological Applications
- Reproductive strategies in plants include sexual (through seeds) and asexual methods (such as cuttings).
- Modern biotechnology applications involve genetic modification and tissue culture techniques to enhance crop qualities.
- Notable contributions from Filipino scientists have advanced research in plant reproduction and biotechnology.
