Responsibility and rights, education and experience, teaching and guidance. 1. Responsibilities and powers: Professors are senior teachers and researchers in institutions of higher learning, with high academic qualifications and professional knowledge, and they undertake important responsibilities such as teaching, scientific research and guiding students, enjoying high academic status and decision-making power, while teaching assistants are teachers' assistants, helping professors to perform teaching tasks, such as assisting course teaching, organizing experiments and correcting homework, with relatively low power and decision-making ability.

2. Education and experience: The professor has rich academic background and experience and has made great achievements in his own field. He can conduct independent research and publish academic papers. A teaching assistant is a student who is pursuing a postgraduate or doctoral degree. Although he also has certain knowledge and research ability, compared with professors, he is still in the learning and training stage.

3. Teaching guidance: The professor is responsible for guiding students in the teaching process, including providing academic advice, guiding research direction, and guiding papers. It has a deeper influence on students' academic development and growth, while teaching assistants mainly assist in teaching and provide support and answers to students to some extent.
