The site of photosynthesis is the thylakoid membrane, which contains integral and peripheral membrane protein complexes, including the pigments that absorb light energy, which form the photosystems. WHAT PIGMENTS ARE RESPONSIBLE FOR PHOTOSYNTHESIS?

Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules.
Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.
The other notable way that Zea leaves differ from those of Syringa is that the vascular bundles in Zea are surrounded by bundle sheath cells. These cells aid in corn’s specialized mode of photosynthesis, called C4 photosynthesis. (Most plants perform C3 photosynthesis. The differences between these two photosynthetic pathways are covered in Bio 6B.)
