🌱 Plant Growth and Development: Role of Hormones in NEET & CBSE Biology

-
Image
Introduction Plant growth and development are crucial chapters in both NEET and CBSE Class 11 Biology. Understanding how plants grow and how hormones regulate this process is important not just for exams, but also for grasping key concepts in plant physiology. --- 🌿 What is Plant Growth? Growth in plants refers to an irreversible increase in size, usually accompanied by an increase in dry mass. It involves cell division (mitosis), cell elongation, and cell differentiation. Plant growth is indeterminate, meaning it continues throughout their life due to the presence of meristems (actively dividing tissues). --- 🔍 Phases of Growth 1. Meristematic Phase – cells are actively dividing. 2. Elongation Phase – cells elongate and expand in size. 3. Maturation Phase – cells differentiate and mature into specific tissues. --- 📈 Growth Curve Follows a sigmoid curve (S-shaped). Has four phases: 1. Lag Phase (slow growth), 2. Log Phase (rapid growth), 3. Declining Phase (slowdown), 4....

Celebrating Teacher’s Day 2025: Honoring the Architects of Knowledge

-
Image
The Origin of Teacher’s Day Teacher’s Day in India commemorates Dr. Sarvepalli Radhakrishnan, born on September 5, 1888. A philosopher, statesman, and the second President of India (1962–1967), Dr. Radhakrishnan believed education was the cornerstone of progress. When students and admirers suggested celebrating his birthday, he humbly proposed that the day be dedicated to honoring all teachers instead. Since 1962, September 5th has been celebrated as Teacher’s Day across the country, a tradition that continues to thrive. Why Teachers Matter Teachers are more than just educators—they are mentors, role models, and catalysts for change. On this Teacher’s Day, let’s reflect on their impact: Shaping Minds: They introduce students to new ideas, critical thinking, and problem-solving skills. Building Character: Beyond academics, teachers instill values like discipline, empathy, and resilience. Inspiring Futures: Many successful individuals credit a teacher for sparking...
