Biological Classification – NEET MCQs with Concept Reminders (Class 11 NCERT)

Durastudy provide in this post, we’re diving into Chapter 2 – Biological Classification – one of the most concept-heavy chapters in Class 11 NCERT. But don’t worry – we've broken it down into simple NEET-style MCQs, each with a short Concept Reminder to help you revise smarter, not harder.

MCQs + Concept Reminders

Q1. Who proposed the Five-Kingdom classification system?
A) Aristotle
B) Ernst Haeckel
C) R.H. Whittaker
D) Linnaeus

Answer : C) R.H. Whittaker

Concept Reminder:
Whittaker’s system (1969) gave us the five kingdoms we still use today: Monera, Protista, Fungi, Plantae, and Animalia.

Q2. Which kingdom includes prokaryotic organisms?
A) Protista
B) Monera
C) Fungi
D) Plantae

Answer: B) Monera

Concept Reminder:
All bacteria and cyanobacteria (blue-green algae) fall under Monera – they have no true nucleus.

Q3. Amoeba belongs to which kingdom?
A) Fungi
B) Protista
C) Monera
D) Plantae

Answer : B) Protista
Concept Reminder:
Amoeba is a unicellular eukaryote, so it fits perfectly in Protista.

Q4. Which of the following is not a feature of fungi?
A) Saprophytic nutrition
B) Multicellular (mostly)
C) Prokaryotic
D) Cell wall with chitin

Answer : C) Prokaryotic
Concept Reminder:
Fungi are eukaryotic, not prokaryotic. Their cell walls contain chitin, not cellulose.

Q5. Which kingdom includes organisms with both autotrophic and heterotrophic modes of nutrition?
A) Monera
B) Plantae
C) Fungi
D) Animalia

Answer : A) Monera
Concept Reminder:
Some bacteria can photosynthesize (autotrophs), while others feed on organic matter (heterotrophs). Hence, Monera includes both.

Q6. Which organism has both plant and animal features?
A) Paramecium
B) Euglena
C) Amoeba
D) Plasmodium

Answer : B) Euglena

Concept Reminder:
Euglena photosynthesizes (like plants) and can also feed on food (like animals) when light is not available.

Q7. Slime molds are placed in which kingdom?
A) Fungi
B) Protista
C) Plantae
D) Animalia

Answer : B) Protista
Concept Reminder:
Slime molds are weird and wonderful! They behave like fungi while feeding and like amoebas when moving – hence placed in Protista.

Q8. Archaebacteria can survive in:
A) Normal conditions
B) Cold regions
C) Extreme environments

D) Only in water

Answer : C) Extreme environments
Concept Reminder:
Archaebacteria live in extreme places like hot springs, salty lakes, and methane-rich guts – they’re the original survivors!

Q9. Mycoplasma is unique because:
A) It is multicellular
B) It has no DNA
C) It lacks a cell wall
D) It can do photosynthesis

Answer : C) It lacks a cell wall
Concept Reminder:
Mycoplasma is the smallest living organism and has no cell wall – that's why it can change shape easily.

Q10. Which group includes unicellular eukaryotes?
A) Monera
B) Protista
C) Fungi
D) Plantae

Answer : B) Protista
Concept Reminder:
If it’s unicellular and has a true nucleus, it belongs to Protista.

Q11. Kingdom Fungi includes organisms that are mostly:
A) Autotrophs
B) Parasites
C) Saprophytes
D) Chemosynthetic

Answer : C) Saprophytes
Concept Reminder:
Most fungi feed on dead organic matter – that’s why they’re called saprophytes.

Q12. Which of the following is not an example of Monera?
A) Bacteria
B) Cyanobacteria
C) Euglena
D) Archaebacteria

Answer : C) Euglena

Concept Reminder:
Euglena is a protist, not a prokaryote – so it doesn’t belong in Monera.

Q13. Which kingdom has organisms that are all heterotrophic and multicellular?
A) Animalia
B) Plantae
C) Fungi
D) Protista

Answer : A) Animalia
Concept Reminder:
Animals can’t make their own food and are multicellular by nature – that’s why they belong in Kingdom Animalia.

Q14. Which organism causes malaria?
A) Amoeba
B) Paramecium
C) Euglena
D) Plasmodium

Answer : D) Plasmodium

Concept Reminder:
Plasmodium, a protozoan protist, causes malaria and lives inside red blood cells.

Q15. What is the mode of nutrition in fungi?
A) Photosynthetic
B) Chemosynthetic
C) Absorptive
D) Ingestive

Answer : C) Absorptive
Concept Reminder:
Fungi secrete enzymes and absorb nutrients from decaying matter. Hence, absorptive heterotrophs.

Understanding the classification of life is the first step in mastering biology.
If you revise these MCQs along with the concept reminders, you’re building a rock-solid foundation for tougher topics ahead.
