Question

how does co₂ enter and o₂ leave the leaf cells? by inhaling co₂ and exhaling o₂ through the vascular bundle through the mesophyll cells through stomata openings through water rewatch

Explanation:

Stomata are tiny openings on the leaf surface. They allow \(CO_2\) (needed for photosynthesis) to enter the leaf cells and \(O_2\) (a by - product of photosynthesis) to leave. Inhaling and exhaling is a characteristic of animals. The vascular bundle is for transporting water, minerals, and nutrients. Mesophyll cells are the site of photosynthesis but not the entry/exit point for gases. Water is not the medium for gas exchange in this context.

Answer:

through stomata openings
