A group of students is trying to grow a kelp plant in a tank without any others animals. They use a temperature regulation system to keep the water temperature at about 12°C. They bury the holdfast below the soil that has been enriched with nutrients and place the plant near a window in direct sunlight. However, over a few weeks the kelp plant withers and dies. Why did this happen?

Kelp is very sensitive to temperature change. Placing the plant near the window and exposing it to direct sunlight will result in continuous warming of the water in which the kelp plant is growing. Research has shown that kelp plant degrades very quickly when temperature increases due to tissue loss.
