Question

A high school student is carrying out a science project. She plants alfalfa seeds, and encloses an area planted with one set of alfalfa seeds within a box covered in red cellophane (which reflects light of red wavelengths). She leaves another set of planted alfalfa seeds uncovered. What do you expect she'll find in these two alfalfa populations when her science project is over?

Answer 1

Answer:

The answer is the germination rate will be higher in the uncovered seed set.

Explanation:

Red light affects phytochrome reversibility and is the most important for photosynthesis, flowering and fruiting regulation. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production. Therefore, the uncovered plants will germinate in more numbers.
