Answer:
a) Increased by exposure of Light
Explanation:
According to the table provided in the full question, Petri dish labelled A was covered for the first week and showed to have the least number of seed growth (i.e 12 germinated seeds). On the other hand Petri Dish B showed to have the highest number of growth for the first week (i.e 20 germinated seeds).
Since Dish A was covered with an opaque cover to block light entry for the first week differentiating it from Dish B ( which was not covered), explaining the reason for the least number of tobacco seeds germinated.
In most cases, to aid proper germination of seeds light exposure is required, hence the key definition in germination "which is the process whereby a seed begins to grow when placed under proper conditions".
According to the results of this experiment, germination of tobacco seeds during the first week is: Increased by exposure of Light.
a) increased by exposure to light
From the experiment, we can infer that:
- According to the table provided in the full question, Petri dish A was covered for the first week and showed to have the least number of seed growth (i.e. 12 germinated seeds).
- On the other hand Petri Dish B showed to have the highest number of growth for the first week (i.e. 20 germinated seeds).
- Since, Dish A was covered with an opaque cover to block light entry for the first week differentiating it from Dish B ( which was not covered), explaining the reason for the least number of tobacco seeds germinated.
- In most cases, to aid proper germination of seeds light exposure is required, hence the key definition in germination "which is the process whereby a seed begins to grow when placed under proper conditions".
Therefore, option a) is correct.
