An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.
A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.

Explanation:
Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
