Exploring Plant Growth: The Effects of Light and Water on Cress

In this experiment, we examined how different conditions affected the growth of cress plants. We used three identical cups, each containing the same amount of cotton wool and seeds, to ensure fairness. One cup was placed in a light spot with water, another in light with no water, and the last one in darkness with water. After one week, we observed the differences in growth, showcasing how essential light and water are for plant development. Can you identify and draw the various cress plants from each condition?
