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