Stomata are small openings or pores found on the surface of leaves and stems of plants. They play a crucial role in the process of gas exchange, allowing the plant to take in carbon dioxide (CO2) from the atmosphere for photosynthesis and release oxygen (O2) as a byproduct. Additionally, stomata are involved in the regulation of water vapor loss through a process called transpiration.

Each stoma (singular of stomata) is flanked by two specialized cells known as guard cells. These guard cells can change shape to open or close the stomatal pore, thereby controlling the exchange of gases and the loss of water vapor. When the guard cells are turgid (full of water), the stomatal pore opens, and when they lose water and become flaccid, the pore closes.

In summary, stomata are essential for photosynthesis, respiration, and transpiration in plants, helping to maintain the balance of gases and water within the plant.

Suppose a company incurred 1 million in expenses related to the restructuring of its business. These expenses related to store closings and severance pay for terminated employees. Because the restructuring is going to cause the company to have a "bad year," the CFO would like to make it a "really bad year." The CFO encourages the chief accountant to over-estimate certain expenses and charges. The CFO explains, "If we take the extra charges this year, then we don't have to report those charges in future years." Required: 1. Understand the reporting effect: If the chief accountant follows the CFO's request, how will net income be affected in the current year? How will it be affected in future years? 2. Specify the options: If the chief accountant does not follow the CFO's request, how is the balance of retained earnings affected in the current year? 3. Identify the impact: Are investors and creditors potentially harmed by the CFO's suggestion? 4. Make a decision: Should the chief accountant follow the advice of the CFO? 1. Net income will be in the current year and in future years. 2. The balance of retained earnings will be in the current year. 3. Are investors and creditors potentially harmed by the CFO's suggestion? 4. Should the chief accountant follow the advice of the CFO?
