Question

Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit

Answer 1

Answer:

False

Explanation:

Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.

Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.

In addition, bacteria can have different forms of "obtaining food"

Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.

Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.
