Original video: https://youtu.be/HF8KMq8PQng Presented on: 14 Jan 2026 Let’s dive into the science behind chloroplasts and mitochondria! Chloroplasts are the green organelles in plant cells that capture sunlight, using it to make sugars and release oxygen through photosynthesis. Mitochondria, often called the ‘powerhouses,’ take those sugars and oxygen and break them down to produce ATP—the energy currency of the cell—while releasing carbon dioxide and water. Notice how the p

Original video: https://youtu.be/2aJAXRgvPks Presented on: 14 Jan 2026 Hi everyone! This 3D clay model illustrates the vital relationship between the two "powerhouses" of the cell. The Chloroplast is the site of photosynthesis, where light energy is captured by chlorophyll in the thylakoids (stacked into grana) to produce carbohydrates. Mitochondrion on the other hand, is the site of cellular respiration, where the matrix and folded cristae work together to break down sugars

Original video: https://youtu.be/jVOKReBkEG0 Presented on: 14 Jan 2026 Hi everyone! Let’s learn a bit about the fascinating connection between the chloroplast and the mitochondrion. Chloroplasts and mitochondria are deeply connected through a continuous cycle of energy and matter within the cell. Chloroplasts capture sunlight to build energy-rich sugars and release oxygen. Mitochondria then consume that very oxygen to break down the sugars, releasing the stored energy in a fo
