Question

Cardinal temperature is related to
A. Minimum temperature
B. Optimum temperature
C. Maximum temperature
D. All of the above

Answer 1

Cardinal temperatures are minimum, optimum and maximum temperature at which growth of plant is seen.

Complete Answer:
- As we know this fact that minimum temperature is the term used to define the lower limit of the survival range for an organism.
- Secondly, optimum temperature is the exact point where the growth will be at the topmost level which means it should be given to the organism to grow properly.
- Maximum temperature is the term that is used in order to tell the upper limit for the survival of the organism.
- This acts as the topmost level above which there will not be growth or rather if growth happens it will be at a very low level. Now it is clear that all the above given are the limits or points present in the cardinal temperature.

So, the correct option is D as all these are the terms used to define the temperature points.

Note: It is noted that cardinal temperature involves the whole range from the lower limits till the upper limits and also the point in between them which causes the growth of an organism. This temperature plays a major role in the growing of an organism.
