Tomatoes contain two pigments for photosynthesis—chlorophyll, which is green, and lycopene, which is red. When tomatoes start to grow, they contain much less lycopene than chlorophyll, which gives them their green color. But when harvest season arrives, the days shorten and temperatures drop, causing chlorophyll to dissolve and lycopene to take over the shade of [...]

Gold Nanoparticles Could Turn Trees into Streetlights

Scientists in Taiwan discovered that placing gold nanoparticles in plants made them glow, which could turn them into an effective form of nighttime illumination: By implanting the gold nanoparticles into the leaves of the Bacopa caroliniana plants, the scientists were able to induce the chlorophyll in the leaves to produce a red emission. Under a high [...]

Green Sea Slug Is Part Animal, Part Plant

Some animals eats algae and incorporates the algae’s chlorophyll into its own body. According to Sidney K. Pierce of the University of South Florida in Tampa, the sea slug Elysia chlorotica no longer has to, because it has incorporated enough of the plant’s genes into its own DNA to manufacture chlorophyll in its own body! The [...]
