Photosynthesis: Nature's Solar Power
Think of photosynthesis as the ultimate solar panel system that keeps all life on Earth running. Chloroplasts contain a green pigment called chlorophyll that absorbs light energy to power this amazing process.
The basic equation is surprisingly simple: carbon dioxide + water → glucose + oxygen. This endothermic reaction needs energy input from sunlight to work, which is why plants can't photosynthesise in the dark.
But what happens to all that glucose? Plants are pretty clever with their sugar - they use it for cellular respiration to release energy, build cellulose to strengthen cell walls, create starch for long-term storage, and even make amino acids by combining glucose with nitrate ions.
Quick Tip: Remember that starch is perfect for storage because it's insoluble - unlike glucose, it won't draw water into cells through osmosis and cause them to burst!
