Questions and Answers
How does a plant grow?
Plant growth involves cell division, elongation, and differentiation, contributing to the development of roots, stems, and leaves.
How important is water to plants?
Water is essential for photosynthesis, nutrient transport, and maintaining plant structure.
How do plants transport food to their systems?
Plants transport food through the phloem, while water and nutrients are transported through the xylem.

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.
