Biology The Cell MCQs Chapter 4 Class 11

The Cell in Biology for Entry Tests and FSC Board Exams

The Cell is a fundamental topic in Biology and forms the basis of understanding all living organisms. It is crucial for students preparing for MDCAT, NUMS, AKU, NUST, UET, ECAT, and FSC board exams (First Year & Second Year). This topic includes essential concepts such as cell theory, structure and functions of organelles, plasma membrane, cytoplasm, nucleus, and cell division, which are frequently tested in both board and competitive exams.
