Study Notes
Plant Growth and Development
- Plants grow through a combination of cell division and elongation, utilizing energy from photosynthesis.
- Growth occurs at specific sites called meristems, which are regions of active cell division.
Importance of Water to Plants
- Water is essential for various physiological processes, including photosynthesis, nutrient transport, and temperature regulation.
- It constitutes a significant portion of plant tissue and aids in maintaining turgor pressure for structural integrity.
Transport System in Plants
- Plants have a vascular system, consisting mainly of xylem and phloem, to transport water, nutrients, and food.
- Xylem: Responsible for transporting water and minerals from roots to other parts of the plant.
- Phloem: Transports organic nutrients, particularly sugars produced during photosynthesis, to different plant tissues.
Plant Nutrition
- Seventeen essential elements identified by botanists are crucial for plant nutrition, including macronutrients (like nitrogen and potassium) and micronutrients (such as iron and zinc).
- Adequate nutrition supports processes like growth, reproduction, and disease resistance.
Plant Hormones, Responses, and Feedback Mechanisms
- Plant hormones (such as auxins, gibberellins, and cytokinins) play critical roles in regulating growth, development, and responses to environmental stimuli.
- Growth Promoters stimulate growth and development, while Growth Inhibitors slow down or halt growth processes.
Reproduction and Modern Biotechnological Applications
- Advances in plant biotechnology have led to improved crop varieties, pest resistance, and higher yields.
- Filipino scientists have significantly contributed to plant biotechnology, enhancing agricultural practices and sustainability.
