Cell: The Unit of Life
Every living organism is built from cells, and NEET Biology treats this chapter as the foundation for everything that follows in cell division, genetics and physiology. The questions here reward precision: knowing not just what an organelle is called, but what it actually does and how it differs from similar-looking structures.
This is NEET Biology's genetics chapter, and it's one of the highest-yield topics in the exam because the underlying logic (Mendelian ratios, Punnett squares, pedigree reading) repeats across many question styles. Getting comfortable with the reasoning matters more than memorising ratios by rote.
