Hey Saloni,
Bachelor in Pharmacy is a 4-year undergraduate degree course in which a student learns to prepare and dispense drugs.
The course includes subjects like Biology (Anatomy and Physiology), Chemistry, Pharmaceutics, Pharmacology, Pharmacognosy,etc.
As according to your question, I want to tell you that in  this course (Pharmacy) you have to study both of these subjects widely with detail.
When it comes to biology, the course in initial semesters include study about human Anatomy and Physiology and in later semesters importance of plants are also taught to you in the course.
And now if we talk about chemistry, in initial semesters you are taught about inorganic chemistry and Electrochemistry part and in the later semesters complete organic chemistry is included in the syllabus of B.Pharmacy and also physical chemistry part is included in the course.
So, in short I would say that complete Biology and Chemistry of class 11th and 12th is included in the syllabus of B.Pharmacy.
Good Luck!
