NEET · Biology · Cell: The Unit of Life doubts

What does “Cell theory” actually mean in Cell: The Unit of Life, and why does it matter for NEET?

all living organisms are made of cells, and every cell arises from a pre-existing cell.

I keep getting “Cell theory” questions wrong in Cell: The Unit of Life. What's the trap?

forgetting Virchow's addition that cells come only from other cells.

What does “Prokaryotic cell” actually mean in Cell: The Unit of Life, and why does it matter for NEET?

a cell without a membrane-bound nucleus or organelles — like bacteria.

I keep getting “Prokaryotic cell” questions wrong in Cell: The Unit of Life. What's the trap?

thinking prokaryotes have no DNA at all.

What does “Mitochondria” actually mean in Cell: The Unit of Life, and why does it matter for NEET?

the powerhouse of the cell, where aerobic respiration makes most of the ATP; it has its own DNA.

I keep getting “Mitochondria” questions wrong in Cell: The Unit of Life. What's the trap?

assuming all cellular energy is made in mitochondria (glycolysis is in the cytoplasm).

What does “Ribosomes” actually mean in Cell: The Unit of Life, and why does it matter for NEET?

tiny non-membrane-bound structures that build proteins.

I keep getting “Ribosomes” questions wrong in Cell: The Unit of Life. What's the trap?

listing ribosomes as membrane-bound organelles.

What does “Cell membrane” actually mean in Cell: The Unit of Life, and why does it matter for NEET?

a selectively permeable boundary described by the fluid-mosaic model.

I keep getting “Cell membrane” questions wrong in Cell: The Unit of Life. What's the trap?

thinking the membrane lets everything pass freely.

What is the difference between prokaryotic cell and eukaryotic cell?

Prokaryotic cells (bacteria) have no nucleus or membrane-bound organelles; eukaryotic cells (plants, animals) have a true nucleus and organelles.

What is the difference between plant cell and animal cell?

A plant cell has a cell wall, chloroplasts and a large vacuole; an animal cell has none of these but has centrioles.

What is the difference between rough ER and smooth ER?

Rough ER is studded with ribosomes and makes proteins; smooth ER lacks ribosomes and makes lipids.

How is Cell: The Unit of Life tested in NEET, and what should I focus on?

Prioritise the core ideas: Cell theory, Prokaryotic cell, Mitochondria.

What are the most common mistakes students make in Cell: The Unit of Life?

prokaryotes do have DNA, held in a nucleoid region — they just lack a nuclear membrane.

How do I revise Cell: The Unit of Life quickly before the exam?

One-page summary of Cell theory, Prokaryotic cell, Mitochondria, then timed previous-year questions.
