There are a few differences between animal cells and plant cells.
Plant cells have cell walls, and animal cells do not.
Plant cells have a large central vacuole and animal cells do not.

Photosynthesis and respiration work together by creating the energy and transporting it.
The process are similar because they both take something in, and let something else out.
The processes complement eachother by Respiration being able to take oxygen to the leaves, and the leaves using that oxygen to power their chemical reaction.
Good luck there friend!
