The answer is guard cells.
Guard cells are cells surrounding each stoma. They help regulate the rate of transpiration by opening and closing the stomata. They are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore (stoma).

After a scorpion sting, the local reactions can last for seven to ten days. They are generally less problematic and usually go away without issues in a few days. The more extreme bites can lead to fever, pain, and muscle aches for a few days and more extreme injuries to the skin.
However, the signs of paralysis after scorpion sting start with difficulty in swallowing and opening the mouth. The influences of scorpion stings may comprise both systematic and local issues. The initial signs may involve swelling, pain, sweating, excessive sweating, and abdominal pain.
Endocytosis is a term used to describe a process of active transport that facilitates the movement of particles such as molecules and parts of a cell or the whole cell into a cell.The best scenario for the process occurs when a cell needs to pass/transport molecules that are large and cannot move through the membrane passively.
