The principal difference is that plant cells have a cellulose cell wall as well as a cell membrane. Plant cells usually contain chloroplasts in which photosynthesis takes place.

A) Plant cells have cell walls, which make them appear rectangular-shaped. These structures are composed of cellulose, hemicellulose, and a variety of other materials.


B) Plant cells have chlorophyll, the light-absorbing pigment required for photosynthesis. This pigment is contained in structures called chloroplasts, which makes plants appear green.


C) Plants cells have a large, central vacuole. While animal cells may have one or more small vacuoles, they do not take up the volume that the central vacuole does (up to 90% of the entire cell volume!). The vacuole stores water and ions, and may be used for storage of toxins.

D) In addition, some plant cells (especially those found in seeds) have specialized microbodies called glyoxysomes. In the picture above, these appear as black dots scattered throughout the cytoplasm. These function in converting fatty acids to carbohydrates.

E) Another difference is that plant cells contain plastids while animal cells don't.

F) Animal cells contain centrioles and lysosomes which are not found in typical plant cells

An animal cell is a form of eukaryotic cell which make up many tissues in animals.Tthey 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.Human cells are biologically categorized as animal cells.
The most significant organelles of an animal cell include:
Cytoplasm
All cells consist of a jelly-like substance called cytoplasm. The cytoplasm allows substances such as food and oxygen to move around within the cell.
Cell membrane
Surrounding the cytoplasm is a soft and thin cell membrane, usually a phospholipid bilayer containing protein channels that allow specific molecules to move in and out of the cell as required. The cell membrane holds the cytoplasm inside it. It also controls substances that go in or out of the cell.
Nucleus
In both plant and animal cells, there is a nucleus found in the cytoplasm. The nucleus is a very important part of a cell. It controls everything that happens inside the cell.The nucleous is a structure inside the nucleus.It controls everything that the nucleus does.
Other Components
There are also very many other components; such as mitochondria, vacuoles and lysosomes. These all play a very important part in the function of a cell.



Plant cells
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.

A cell wall made 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.
Plant groups without flagella (including conifers and flowering plants) also lack centrioles that are present in animal cells.

The difference between a plant cell and animal cell is that an animal cell has NO cell wall and has no vacuole system! Hope this helped!

Plants have one large vacuole. Animals have many vacuoules. Plants have a cell wall and chloroplasts. Animanls have neither. Animals have centrioles. Plants do not. This is the complete list of the differences.

plant cell - no true nucleus, has cloroplast, has cell wall, prokaryotic

animal cell - true nucleus, cell membrane, eukaryotic
