What is the difference between Photoshop Student edition and Photoshop extended? - photoshop extended

What is the difference between the student edition of Photoshop and Photoshop Extended? There is a big difference in price between them. Are there any restrictions on the software on a single student, or just less expensive for a student? Thanks in advance
