Pumpkin seedling. Macrophotograph of a pumpkin seedling, Cucurbita pepo, soon after germination. The seedling has unfurled its first leaves (at centre right and lower left). Another leaf is ready to unfurl between the first two leaves. The leaves grow against gravity or towards light and provide food for the plant using sunlight. The seed remains dormant until the right conditions trigger germination. For a photo of the seedling with another leaf developed see image B787/301.
