A botanical infographic explaining photosynthesis through a magnified leaf cross-section. Center: a detailed cutaway showing the waxy cuticle, palisade and spongy mesophyll layers, a stoma with guard cells, and green chloroplasts. Blue curved arrows trace incoming water and CO2; orange arrows show released oxygen; a yellow sunbeam strikes the top. Flat vector illustration with soft gradients on a cream background. Bold sans-serif title 'How a Leaf Makes Food', numbered callout boxes, and the equation 6CO2 + 6H2O to C6H12O6 + 6O2 along the base. Botanical green and amber palette.
