Take notes on the 2 non-human examples of living things maintaining homeostasis negative

Answer 1

1) Plants: Plants are non-human examples of living things that maintain homeostasis. One way they do this is through stomatal regulation. Stomata are tiny pores found on the surface of leaves that allow for gas exchange. When plants are subjected to dry conditions or high temperatures, they close their stomata to prevent excessive water loss through transpiration. By regulating the opening and closing of stomata, plants are able to maintain water balance and prevent dehydration.

Additionally, plants can also maintain homeostasis through the process of photosynthesis. Through this process, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. They are able to regulate the rate of photosynthesis in response to changing environmental conditions such as light intensity, temperature, and the availability of water and nutrients. This helps plants maintain the balance of energy production and consumption necessary for their survival.

2) Bacteria: Bacteria are another example of non-human living things that maintain homeostasis. They are able to do so through various mechanisms, one of which is osmoregulation. Bacteria inhabit diverse environments, including those with extreme temperatures, pH levels, and salinity. To survive in such conditions, bacteria adjust their internal osmotic pressure by regulating the concentration of solutes inside their cells. They can either pump out or accumulate compatible solutes, such as sugars or amino acids, to maintain the proper water balance within their cells.

Moreover, bacteria can regulate their internal temperature through a process known as thermoregulation. Some thermophilic bacteria, which thrive in extreme hot environments, possess special heat-shock proteins that stabilize their cellular structures and enzymes at high temperatures. On the other hand, psychrophilic bacteria, found in extremely cold environments, have the ability to produce antifreeze proteins that prevent the formation of ice crystals within their cells.

In conclusion, plants and bacteria are two examples of non-human living things that maintain homeostasis. Plants regulate stomatal opening, maintain water balance, and adjust the rate of photosynthesis to adapt to changing environmental conditions. Bacteria, on the other hand, adjust their osmotic pressure and internal temperature to survive in extreme environments.
