GROWTH AND DEVELOPMENT

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A scientist planted several radish plants at work. She also planted several radish plants at home. She observed that the plants grown at home were taller and had more leaves than those grown at work. She proposed the idea that genetic differences were responsible for the differences. Which of the following is the best argument AGAINST her idea?
A
Changing environments can alter plants’ genetic material
B
Genetic factors cannot influence plant height or leaf growth
C
The genetic material of all the plants would be the same
D
Environmental factors are usually stronger than genetic factors
Explanation: 

Detailed explanation-1: -The plants that were not exposed to light grew 15.7 millimeters more on average, and the difference of growth between no light and half light plants was 7.27 millimeters. In conclusion, the plants that were exposed to no light whatsoever, were the ones who grew significantly larger than the other plants.

Detailed explanation-2: -Plant growth is affected by several factors such as seed variety, amount of water, soil type, amount of light, temperature, humidity, and other. The factors are displayed in the diagram below. You will use two variables in the experiment: seed variety and amount of water.

Detailed explanation-3: -A plants response to light has been well documented and studied. It is known to be due to differential elongation of the cells in the plant stem. Stem cells away from the light elongate in response to special auxins (growth hormones) causing the plant stem to bend towards the light.

Detailed explanation-4: -Shoots usually move towards the light; roots usually move away from it.
