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.

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...

Liverworts Example: Marchantia Plant body is dorsiventral, thalloid Asexual reproduction: by fragmentation and gemmae Sexual reproduction: male and female sex organs borne on separate structures 2. Mosses Example: Funaria, Polytrichum Gametophyte has two ...
