Study Notes
Plant Structures and Functions
- Roots anchor plants and absorb water and nutrients from the soil.
- Stems provide support and transport water, nutrients, and sugars between roots and leaves.
- Leaves are the primary site for photosynthesis, capturing sunlight to convert carbon dioxide and water into glucose.
Plant Phases and Characteristics
- Vegetative phase focuses on growth and development of leaves and stems.
- Flowering phase involves reproduction through the formation of flowers, leading to fertilization.
- Dormant phase occurs when growth halts, often due to unfavorable environmental conditions.
Terms and Meanings
- Germination is the process of a seed developing into a new plant.
- Pollination refers to the transfer of pollen from male anthers to female stigmas.
- Photosynthesis is the process by which plants convert light energy into chemical energy.
Plant Processes and Descriptions
- Photosynthesis transforms light energy into glucose, fueled by chlorophyll in leaves.
- Respiration is the process by which plants convert glucose and oxygen into energy, releasing carbon dioxide and water.
- Transpiration involves the loss of water vapor from plant leaves, aiding nutrient transport and cooling.
Differentiation Process
- The term for undifferentiated cells becoming specialized is cell differentiation, a crucial process in plant development.
Preceding Phase to Flowering
- The phase that precedes flowering in a plant's life cycle is the vegetative phase, during which the plant accumulates energy reserves.
Growth Factors in Trees
- The main factor contributing to the increase in height or girth of trees is secondary growth, primarily driven by the activity of the cambium layer.
Light Response in Plants
- The response of plants to the relative lengths of light and dark periods is called photoperiodism, influencing flowering and dormancy cycles.
Plant Development Modifiers
- Substances that promote, inhibit, or modify aspects of plant development are known as plant hormones or phytohormones.
