Homework Answers
A. Red light is involved in the germination of seeds as it helps in morphogenesis. This process is known as photo morphogenesis. Phytochromes in the plant respond to these lights.
B. Far red light inhibits germination as the plant things that it is not receiving light. It understands it as darkness.
C. The plant will not be able to germinate as the last stimulus was darkness.
Plant germinate only in the red light so the last stimulus in this case was darkness which can lead to death of the plant.

ntroduction: Photosynthetic plants require light to make sugars in order to produce the energy to grow. Yet, when we think about plants needing light to grow, we do not intuitively understand how light affects the rate at which plants grow taller. Plants do exhibit positive phototropism, which means they grow towards light....
