Responses
lack of growth
lack of growth
the same amount of growth
the same amount of growth
more growth
more growth
uncontrollable growth
lack of growth
The correct answer is "lack of growth". Bacteria that require light to reproduce will not be able to grow in a dark environment.
Bacteria that require light to reproduce will show "lack of growth" compared to bacteria that do not require light to reproduce.
To understand why, we need to consider the process of photosynthesis. Bacteria that require light for reproduction typically carry out photosynthesis, which is the process of converting light energy into chemical energy to fuel their growth and reproduction. In a dark environment, these light-dependent bacteria lack the necessary energy source (light) to carry out photosynthesis effectively. As a result, their growth and reproduction are hindered, leading to a lack of growth.
On the other hand, bacteria that do not require light to reproduce typically rely on other sources of energy, such as organic compounds or chemical reactions, to sustain their growth and reproduction. These bacteria are not dependent on light, so they can still continue their growth and reproduction even in a dark environment. Therefore, they would show the same amount of growth as they would in a lighted environment.
In summary, bacteria that require light for reproduction will exhibit a lack of growth when exposed to a dark environment, while bacteria that do not require light will show the same amount of growth.
