FAQs on Questions: Plant Growth & Development Video Lecture - Biology for ACT

1. What are the stages of plant growth and development?
Ans. Plant growth and development can be divided into several stages. These include germination, seedling establishment, vegetative growth, flowering, and fruiting. Each stage has specific characteristics and requirements for the plant to progress to the next stage.
2. How does light affect plant growth and development?
Ans. Light is an essential factor for plant growth and development. It is necessary for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth. Different wavelengths of light have specific effects on plant growth, such as promoting flowering or influencing leaf formation.
3. What role do hormones play in plant growth and development?
Ans. Hormones are chemical messengers in plants that regulate various physiological processes. They play a crucial role in plant growth and development, controlling processes like cell division, elongation, and differentiation. Hormones such as auxins, gibberellins, cytokinins, abscisic acid, and ethylene are involved in different aspects of plant growth and development.
4. How do plants respond to environmental stimuli during growth and development?
Ans. Plants have the ability to respond to various environmental stimuli to adapt and optimize their growth and development. They can respond to factors such as light intensity, temperature, water availability, and nutrient levels. These responses can include changes in leaf orientation, stem elongation, root growth, and flowering time, among others.
5. What are the factors that influence plant growth and development?
Ans. Several factors influence plant growth and development. These include genetic factors, environmental conditions (light, temperature, water, nutrients), hormone levels, and interactions with other organisms like symbiotic relationships with fungi or pollination by animals. Each factor can have a significant impact on the overall growth and development of a plant.
