Cell: The Unit of Life — solved practice questions

6 NEET Biology questions with step-by-step solutions. Attempt each, then reveal the answer.

  1. Q1easy

    Who first discovered the cell?

    • ARobert Hooke
    • BCharles Darwin
    • CLouis Pasteur
    • DGregor Mendel
    Show answer & solution

    Correct answer: (A) Robert Hooke

    Robert Hooke discovered the cell in 1665 while observing cork under a microscope.

  2. Q2easy

    Which organelle is called the 'powerhouse of the cell'?

    • Anucleus
    • Bribosome
    • Cmitochondria
    • Dgolgi apparatus
    Show answer & solution

    Correct answer: (C) mitochondria

    Mitochondria produce energy (ATP), so they are called the powerhouse of the cell.

  3. Q3medium

    Which structure is present in plant cells but absent in animal cells?

    • Anucleus
    • Bcell wall
    • Cmitochondria
    • Dribosome
    Show answer & solution

    Correct answer: (B) cell wall

    Plant cells have a rigid cell wall (and chloroplasts) which animal cells lack.

  4. Q4easy

    The control centre of the cell, which contains the DNA, is the:

    • Acytoplasm
    • Bnucleus
    • Cvacuole
    • Dlysosome
    Show answer & solution

    Correct answer: (B) nucleus

    The nucleus contains the genetic material (DNA) and controls cell activities.

  5. Q5medium

    Organisms whose cells lack a true (membrane-bound) nucleus are called:

    • Aeukaryotes
    • Bprokaryotes
    • Cprotists
    • Dfungi
    Show answer & solution

    Correct answer: (B) prokaryotes

    Prokaryotes (e.g. bacteria) have no membrane-bound nucleus; eukaryotes do.

  6. Q6medium

    Which organelle is the site of protein synthesis?

    • Aribosome
    • Blysosome
    • Cvacuole
    • Dchloroplast
    Show answer & solution

    Correct answer: (A) ribosome

    Ribosomes are the sites where proteins are synthesised.
