Phytochromes are light-sensitive proteins found in plant cells that play a crucial role in the plant's understanding of its environment, particularly in detecting light. If seeds are planted too deep, the absence of light means phytochromes cannot absorb the light necessary for initiating germination processes, leading to the seeds not germinating.
