The system by which gases enter and leave the body is called the respiratory system. It includes organs such as the lungs, nose, and trachea that work together to allow for the exchange of oxygen and carbon dioxide between the body and the environment.
Stomata (stoma)
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.
Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
Substances leave the plant through processes such as transpiration, where water evaporates from the leaves, and translocation, where sugars and other nutrients are transported through the phloem tissue to other parts of the plant for growth and metabolism. Additionally, gases like oxygen and carbon dioxide can enter and exit the plant through tiny openings called stomata on the leaves.
There are pores on the underside of the leaf called stomata they allow transpiration.
Simple diffusion.

Stomata (stoma)
When energy is unable to pass from a system to the surroundings, it is called an isolated system. In an isolated system, energy is conserved, and no energy can enter or leave the system.
A microscope can be used for this.
Oxygen (O2) and Carbon Dioxide (CO2) =)
A system in which neither matter nor enery enters or leaves is a closed system.
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.
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.
pores in the leaves and stomates allow gases to enter and leave the plant

The condition that does not heat to enter or leave the system.
