Master of How leaves eat sunlight

artiteacher Leaves physically move and change shape to capture the perfect amount of sunlight.

artiteacher Chlorophyll is the pigment that absorbs sunlight to kickstart the food-making process.

artiteacher Drag sunbeams into the hungry sprout to learn how leaves turn light into food.
Chloroplast origins: Long ago, chloroplasts were independent living bacteria before they moved inside plant cells.

Which microscopic structures inside plant cells act as the solar-powered factories where photosynthesis occurs?
How do chloroplasts protect themselves inside a plant cell when the sunlight becomes dangerously intense?
