Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A flower is yellow in the warm summer and white in the cold winter. What does this show?
A
The plant changes it’s DNA in different temperatures
B
Gene expression is not influenced by the environment
C
Gene expression is influenced by the environment; the temperature
D
None of the above
Explanation: 

Detailed explanation-1: -Vernalization is an example of temperature influencing the timing of flowering and is defined as the process by which a prolonged exposure to the cold of winter results in competence to flower during the following spring.

Detailed explanation-2: -To survive short periods of heat stress, plants activate a molecular pathway called the heat-shock response. This heat-shock response (common to all organisms) protects cells from damage inflicted by proteotoxic stress, which damages proteins.

Detailed explanation-3: -Vernalization occurs in response to? The process of vernalization is the induction of the flowering process in plants are a result of it being exposed to prolonged sessions of lower temperatures, cold of winter or such an environment.
