CBSE Grade 9 Science | Exploration Cell – The Building Block of Life explained in Tamil. In this video, we continue Chapter 5 – Cell: The Building Block of Life from the new CBSE Grade 9 Science (Exploration) textbook. Students will learn about the mitochondria, the powerhouse of the cell, and understand how cells produce energy in the form of ATP through cellular respiration. We also explore the structure of mitochondria and the importance of the inner membrane and cristae. The lesson then explains plastids, the special organelles found only in plant cells. Students will understand the functions of chloroplasts, chromoplasts and leucoplasts, how plants prepare food by photosynthesis, why flowers and fruits have different colours, and how plants store starch, oils and proteins. Finally, we study vacuoles, their structure and functions in both plant and animal cells. Students will learn how vacuoles store water, minerals, food and waste materials, and why plant cells remain firm due to the large central vacuole. The session also includes interesting textbook discussions, Pause & Ponder questions and Threads of Curiosity to strengthen conceptual understanding. Every topic is explained step by step in simple Tamil with clear diagrams, making it easy to understand textbook concepts, competency-based questions and examinations.
