Study Notes
Plant Growth and Development
- Plant development encompasses growth processes such as cell division, elongation, and differentiation.
- Essential factors influencing plant growth include light, temperature, soil quality, and water availability.
Importance of Water to Plants
- Water is crucial for plant survival, affecting photosynthesis, nutrient transport, and temperature regulation.
- Plants absorb water through root hairs, which increases surface area for efficient water uptake.
Transport System in Plants
- The transport system is primarily divided into two components: xylem and phloem.
- Xylem is responsible for transporting water and minerals from roots to the rest of the plant.
- Phloem transports the sugars produced during photosynthesis from leaves to other parts of the plant for energy use or storage.
Plant Nutrition
- 17 essential elements have been identified as necessary for plant nutrition, including nitrogen, phosphorus, and potassium.
- A balanced supply of these nutrients is vital for optimal growth, influenced by both soil composition and fertilizers.
Plant Hormones, Responses, and Feedback Mechanisms
- Plant hormones (such as auxins, gibberellins, and abscisic acid) regulate growth, responses to environmental stimuli, and developmental processes.
- Growth promoters enhance growth processes, while growth inhibitors may slow down or halt growth under certain conditions.
Reproduction and Modern Biotechnological Applications
- Modern biotechnology includes techniques like genetic modification to enhance crop resistance and yield.
- Significant contributions in plant biotechnology have been made by renowned Filipino scientists who advanced agricultural practices.
Recall and Assignment
- Engaging with the material actively through recall sessions enhances memory retention.
- Assignments provide opportunities to apply knowledge and solidify understanding of plant functions and interactions within ecosystems.
