CO2
Mainly in leave cells. They are modified for photosynthesis

The main parts of a leaf involved in photosynthesis are the chloroplasts, where photosynthesis occurs, and the stomata, which regulate gas exchange for photosynthesis. The mesophyll cells contain the majority of the chloroplasts where photosynthesis takes place, while the veins in the leaf provide the transport system for water and nutrients needed for photosynthesis.
in photosynthesis leave do take carbondidxside from the air and leave oxygen
So animals can take it in and produce more CO2
Yes materials made inside of the nucleus such as ribosomes must leave
Carbon dioxide enters through small pores called stomata on the underside of the leaf. Oxygen is released through the same stomata during photosynthesis.
Proteins that are attached to the ribosomes, I suppose
pores in the leaves and stomates allow gases to enter and leave the plant
The stomata in the epidermis allow oxygen, carbon dioxide and water vapour to enter and leave the leaf. The guard cells also contain chloroplasts for photosynthesis.
Unwanted materials such as waste products, toxins, and excess ions leave the cells through the holes in the plasma membrane. These holes include channels and transporters that allow the passive or active movement of substances in and out of the cell.
in the leaf.it takes in sunlight to start the process of photosynthesis
