Plant cells are quite different from the cells of the other eukaryotic kingdom's organisms. Their distinctive features are:
A large central vacuole (enclosed by a membrane, the tonoplast), which maintains the cell's turgor and controls movement of molecules between the cytosol and sap.[[sr:Биљна ћелија
A close up of cellulose and protein, and in many cases lignin, and deposited by the protoplast on the outside of the cell membrane. This contrasts with the cell walls of fungi, which are made of chitin, and prokaryotes, which are made of peptidoglycan.
The plasmodesmata, linking pores in the cell wall that allow each plant cell to communicate with other adjacent cells. This is different from the network of hyphae used by fungi.
Plastids, especially chloroplasts that contain chlorophyll, the pigment that gives plants their green color and allows them to perform photosynthesis.[[sr:Биљна ћелија
Plants lack centrioles that are present in animal cells.
Like other eukaryotic cells, plant cells typically also have a nucleus, containing most of the cell's DNA, and mitochondria, the 'power plants' of the cell. However, some parts of a living plant's tissue are selectively dead so they can serve the plant without consuming vital nutrients.
n animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical.[citation needed] Human cells are biologically categorized as animal cells.

Gives them life for the most part. Plant cells are a little different in that their chemical changes are more visible. Hence the changing colors of the tree leaves in the Fall.
Animal cells do everything from keeping the body oxidated - to carrying energy and food - to getting rid of waste and foreign bodies such as bacteria and viruses.
It all depends on the application too. This is kind of a broad response, but your question was broad too.
Hope this is useful to you nonetheless...
