Directional growth responses including Phototropism (growth toward light), Gravitropism (response to gravity), and Thigmotropism (response to touch). 🎨 Slide Design and Visual Best Practices
Natural or synthetic chemicals controlling plant activities. Includes auxins, gibberellins, cytokinins, ethylene, and abscisic acid, used to promote, inhibit, or modify growth.
Effective use of a downloaded PPT goes beyond mere presentation. An instructor might integrate interactive elements, such as pausing to ask students to predict the effect of removing the apical meristem (demonstrating auxin's role in apical dominance). Similarly, embedding short time-lapse video clips of seed germination or phototropism within the PPT dramatically enhances engagement. plant growth and development ppt download top
The programmed, natural aging process of plant organs (leaves, flowers, fruits), culminating in death or shedding (abscission). This allows plants to salvage nutrients and redirect them to surviving structures or seeds.

Essential for photosynthesis and photoperiodism (flowering response to day length) [3].
An irreversible, permanent increase in the size of an organ, its parts, or an individual cell. It is quantitative and measurable (e.g., fresh weight, dry weight, length, area, volume). The programmed, natural aging process of plant organs
Plant growth is generally defined as an irreversible increase in size and volume, while development covers the entire life cycle, including differentiation and maturation. A. Seed Germination
