Cress seeds are sown in two identical trays, one kept in the light and one in complete darkness, and both are watered and kept warm. Which prediction about germination is right?

Explanation

Germination runs on supplies already sealed inside the seed, and not one of the steps involved requires light, which is why seeds buried well below the surface come up at all. Light only matters afterwards, once a seedling has leaves and must begin making its own sugar, so the dark tray germinates and then fails later rather than failing to start.
