Plant Kingdom NEET MCQ with Answers
The Plant Kingdom is known as the Kingdom Plantae, encompasses all multicellular, eukaryotic organisms that primarily perform photosynthesis. This kingdom includes a vast diversity of life forms ranging from tiny mosses to towering trees. The Plant Kingdom is fundamental to life on Earth as it produces oxygen and forms the base of most food chains.
The Primary Features of Plant Kingdom
- Eukaryotic: Possess well-defined nucleus and membrane-bound organelles.
- Multicellular: Composed of many cells.
- Autotrophic: Primarily synthesize their own food through photosynthesis.
- Cell Wall: Composed of cellulose.
- Non-motile: Lack the ability to move independently.
- Reproduction: Both asexual (vegetative propagation) and sexual methods.
- Chloroplasts: Contain chlorophyll for photosynthesis.
- Differentiated Body: Specialized tissues for various functions (roots, stems, leaves).

Plant Kingdom MCQ
The Plant Kingdom is a very important chapter in NCERT Syllabus for NEET Examination. This topic is a very vast and requires dedicated hours of learning. In this article, we will go through some multiple-choice-questions related to the NEET Examination.
Plant Kingdom NEET MCQ with Answers
Q1. Phylogenetic system of classification is based upon
A) evolutionary relationship of organisms
B) cytological information
C) structural embryology
D) All of the above
Answer. A
Q2. The earliest system of classification given by ...A....based on gross superficial
morphological traits was called \(\ldots\) B \(\ldots\) Here, A and B are
A) Linnaeus, natural classification
B) Whittaker, natural classification
C) Linnaeus, artificial classification
D) Whittaker, artificial classification
Answer. C
Explanation: (c) Carolus Linnaeus proposed the artificial system of classification. It was based on
assessment of only gross superficial morphological characters like habit, colour, shape, etc., and
vegetative characters.
Q3. Phylogenetic system of classification was given by
A) Engler and Prantl
B) Aristotle
C) Linnaeus
D) Bentham and Hooker
ANswer. A
Explanation: (a) Phylogenetic system of classification was given by Engler and Prantl for the first
time. It was based on evolutionary and genetic relationships of organisms.
Q4. Classification on the basis of all observed characters is known as
A) number and codes taxonomy
B) numerical taxonomy
C) countable taxonomy
D) numerical information taxonomy
Answer. B
Explanation: (b) Numerical taxonomy, is based on all observable characteristics of an organism. Number
and codes are assigned to all the characters and then the data is processed using computers.
In this way, each character is given equal importance and at the same time hundreds of characters can be considered together.
In this way, each character is given equal importance and at the same time hundreds of characters can be considered together.
Q5. Classification done on the basis of cytological information, chromosome structure and their
behaviour, is known as
A) molecular classification
B) cytotaxonomy
C) chemotaxonomy
D) karyotaxonomy
Answer. B
Q6. Phylogenetic system of classification is also known as
A) Artificial system of classification
B) Hutchinson's system of classification
C) Natural system of classification
D) Whittaker's system of classification
Answer. B
Explanation: (b) Phylogenetic system of classification is also known as Hutchinson's system of
classification. John Hutchinson was a botanist in Kew Botanical Garden. He gave more detailed
phylogenetic system of classification after Engler and Prantl, thus this system of classification is
also known Hutchinson's system of classification (1926-1934).
Q7. Algae are
A) chlorophyll bearing autotrophs
B) simple and thalloid
C) Both (a) and (b)
D) heterotroph
Answer. C
Explanation: (c) Algae are chlorophyll bearing, simple, thalloid and autotrophic organism. Their body is
thalloid, i.e. it is not differentiated into root, stems or leaves. Algae are photoautotrophic, i.e.
perform autotrophic mode of nutrition by performing photosynthesis due to the presence of chlorophyll in
their chloroplast.
Q8. An example of colonial alga is
NEET 2017
A) Chlorella
B) Volvox
C) Ulothrix
D) Spirogyra
Answer. B
Explanation: (b) Volvox is a freshwater, green, hollow ball-like colonial alga. Its colony has a fixed
number of cells (500 - 60,000) and is called coenobium.
Q9. In algae, asexual reproduction occurs by the production of different types of spores. The
most common type of spore is
A) aplanospore
B) endospore
C) zoospore
D) oospore
Answer. C
Explanation: (c) Algae produce different types of spores, the most common being the zoospores. These are
motile, flagellated and give rise to new plants on germination.
Q10. Which of the following type(s) of sexual reproduction is/are present in algae?
A) Isogamy
B) Anisogamy
C) Oogamy
D) All of these
Answer. D

FAQs about Plant Kingdom for NEET
- What are the primary divisions within the Plant Kingdom?
Answer. The Plant Kingdom is divided into Bryophytes (mosses), Pteridophytes (ferns), Gymnosperms (conifers), and Angiosperms (flowering plants). - What is the significance of alternation of generations in plants?
Answer. Alternation of generations is a life cycle that alternates between a diploid sporophyte generation and a haploid gametophyte generation, ensuring genetic diversity and adaptation. - What is the main difference between Gymnosperms and Angiosperms?
Answer. Gymnosperms have naked seeds not enclosed in an ovary, while Angiosperms have seeds enclosed within a fruit (ovary). - How do Bryophytes differ from other plant groups?
Answer. Bryophytes lack true vascular tissues (xylem and phloem), roots, stems, and leaves, and they reproduce through spores rather than seeds. - What are the key characteristics of Pteridophytes?
Answer. Pteridophytes are vascular plants with true roots, stems, and leaves, and they reproduce via spores. They do not produce seeds or flowers. - Why are vascular tissues important in plants?
Answer. Vascular tissues (xylem and phloem) are crucial for the efficient transport of water, nutrients and food throughout the plant, supporting growth and survival in various environments.
