Materials enter and leave the nucleus through openings called nuclear pores. These pores regulate the movement of molecules, such as RNA and proteins, between the nucleus and the cytoplasm. They allow for communication and transportation of essential components for cellular functions.
The openings in leaves that allow gases to pass through are called stomata. Stomata help regulate gas exchange by allowing carbon dioxide to enter the leaf for photosynthesis and oxygen to exit, while also enabling water vapor to escape through transpiration.
Are there any openings?

The holes through which gases enter and leave are commonly referred to as "pores" or "stomata," depending on the context. In biological systems, stomata are small openings on the surfaces of leaves that facilitate gas exchange, allowing carbon dioxide in and oxygen out. In other contexts, such as materials science or geology, pores can refer to tiny openings in a material that allow gases to flow through.
Scorpions breathe through four pairs of book lungs on the underside of the abdomen. Great link I found on scorpions for you. Click the link below labeled "scorpions"Scorpions have a six-segmented abdomen. On the underside of each of the last four segments are small paired openings called stigmata.
