Plant Kingdom: key facts for NEET
16 facts the paper keeps asking, each with how it is asked. Copy it onto one page of your notebook: that page is this chapter's handbook.
Cyanobacteria not in Plantae
Cyanobacteria (blue-green algae) are no longer placed in Plantae, so they are not "algae" any more.
Asked as: Assertion-Reason: "Blue-green algae belong to Plantae" (false).
Types of taxonomy
Numerical taxonomy gives every observable character equal importance; cytotaxonomy uses chromosomes; chemotaxonomy uses plant chemicals.
Asked as: "Taxonomy based on chromosome number, structure and behaviour is called ___".
Sexual reproduction in algae
Isogamy: flagellated gametes in Ulothrix, non-flagellated in Spirogyra; anisogamy in Eudorina; oogamy in Volvox and Fucus.
Asked as: match the alga to its type of sexual reproduction.
Economic products of algae
Algin comes from brown algae, carrageen from red algae, agar from Gelidium and Gracilaria; Chlorella is a protein supplement for space travellers.
Asked as: "Agar is commercially obtained from ___".
Green algae (Chlorophyceae)
Green algae have chlorophyll and , pyrenoids holding protein plus starch, and a wall of inner cellulose with outer pectose.
Asked as: "Pyrenoids contain ___" or "the outer layer of the green algal wall is ___".
Brown algae (Phaeophyceae): pigments and food
Brown algae have chlorophyll and with fucoxanthin, and store laminarin or mannitol; their wall is cellulose coated with algin.
Asked as: match the algal class to its pigment and stored food (Table 3.1).
Brown algae: body and zoospores
Brown algal body has a holdfast, a stipe and a frond; zoospores are pear-shaped with 2 unequal lateral flagella; kelps reach .
Asked as: "The leaf-like photosynthetic organ of brown algae is the ___".
Red algae (Rhodophyceae)
Red algae have r-phycoerythrin and chlorophyll and , store floridean starch (like amylopectin and glycogen), have no flagella, and are oogamous.
Asked as: "Floridean starch is the stored food of ___".
Bryophytes: dominant phase
Bryophytes are the amphibians of the plant kingdom; the haploid () gametophyte is the main body, and the sporophyte depends on it.
Asked as: "In bryophytes the dominant, free-living phase is ___".
Sphagnum and pioneer plants
Sphagnum gives peat, used as fuel and as packing material; mosses and lichens are the first to colonise rocks.
Asked as: "Peat is obtained from ___" or "pioneers on bare rock are ___".
Gemmae in Marchantia
In the liverwort Marchantia, gemmae are green, multicellular asexual buds formed in gemma cups.
Asked as: "Gemmae are ___ (asexual / sexual) structures of ___".
Moss life cycle: protonema
In mosses the protonema grows straight from the spore, and the leafy stage arises as a lateral bud on the secondary protonema; e.g. Funaria, Polytrichum, Sphagnum.
Asked as: "The leafy stage of a moss develops from ___".
Pteridophytes
Pteridophytes are the first terrestrial plants with xylem and phloem; the sporophyte is dominant, and the gametophyte is the prothallus.
Asked as: "The gametophyte of a fern is called ___".
Heterospory and seed habit
Selaginella and Salvinia are heterosporous; the embryo developing inside the retained female gametophyte is a precursor to the seed habit.
Asked as: "Development of the embryo within the female gametophyte retained on the sporophyte is a precursor to ___" or "name a heterosporous pteridophyte".
Gymnosperm roots
Pinus roots form mycorrhiza; Cycas has coralloid roots with -fixing cyanobacteria; Sequoia is one of the tallest trees.
Asked as: "Coralloid roots of Cycas are associated with ___".
Monoecious Pinus vs dioecious Cycas
Pinus bears male and female cones on the same tree, while Cycas bears male cones and megasporophylls on different trees.
Asked as: "Which gymnosperm bears male cones and megasporophylls on separate plants?"
Trap
The dominant phase flips between groups. In bryophytes the haploid gametophyte is the main plant and the sporophyte depends on it. In pteridophytes the main plant is the diploid sporophyte, with true roots, stem and leaves, and the prothallus is the small gametophyte.
How does NEET ask Plant Kingdom?
8 real previous-year questions from this chapter, as printed in the paper, each with its worked solution. Answer the first one here with no sign-in.
In which one of the following, the ovules are not enclosed by an ovary wall and remain exposed?
Answer key (C) & worked solution
Correct answer: Option C
The gymnosperms are plants in which the ovules are not enclosed by any ovary wall and remain exposed, both before and after fertilisation. Pinus is a gymnosperm. Funaria is a moss. Selaginella is a pteridophyte.
Which of the following is responsible for peat formation?
Answer key (C) & worked solution
Correct answer: Option C
Species of Sphagnum, a moss, provide peat that has been used as fuel and packaging material because of its water holding capacity.
Which of the following plants is monoecious?
Answer key (D) & worked solution
Correct answer: Option D
When male and female sex organs are present on the same plant body, such plants are said to be monoecious. Chara is monoecious as both male and female reproductive structures are in the same plant body. Cycas circinalis, Carica papaya, and Marchantia polymorpha are dioecious.
Winged pollen grains are present in
Answer key (D) & worked solution
Correct answer: Option D
In pinus, winged pollen grains are present. It is extended outer exine on two lateral sides to form the wings of pollen. It is the characteristic feature of Pinus. The wings of the pollen rise upwards and float in the air during pollination.
Which of the following algae produce Carrageen?
Answer key (A) & worked solution
Correct answer: Option A
Red algae produce carrageen. Carrageen is a common name given to polysaccharides extracted from certain seaweeds like red edible seaweeds. It is used as a gelling, thickening, and stabilizing agent. The cell wall of red algae is composed of agar, carrageen, and funori along with cellulose. In brown algae, the cell wall contains algin while in green algae it is composed of cellulose and pectin. In blue-green algae, the cell wall is composed of mucopeptides.
Genera like Selaginella and Salvinia produce two kinds of spores. Such plants are known as
Answer key (B) & worked solution
Correct answer: Option B
Genera like Selaginella and Salvinia which produce two kinds of spores, macro (large) and micro (small) spores, are known as heterosporous. The megaspores and microspores germinate and give rise to female and male gametophytes, respectively. The female gametophytes in these plants are retained on the parent sporophytes for variable periods. The development of the zygotes into young embryos takes place within the female gametophytes. This event is a precursor to the seed habit and it is considered an important step in evolution.
Which of the following algae contains mannitol as reserve food material?
Answer key (C) & worked solution
Correct answer: Option C
Ectocarpus is a member of Phaeophyceae or brown algae that are found primarily in marine habitats. They possess chlorophyll a, c, carotenoids, and xanthophylls. They vary in colour from olive green to various shades of brown depending upon the amount of the xanthophyll pigment, fucoxanthin present in them. Food is stored as complex carbohydrates, which may be in the form of laminarin or mannitol.

Why does Plant Kingdom show "–" until you answer 3 questions?
Unknown is not zero. Until you answer at least 3 graded questions in Plant Kingdom, ViJEEta shows – instead of a zero or a 50% default. Book exercises can raise chapter mastery up to 0.60, adaptive practice up to 0.75, and only a timed chapter test or mock can certify 0.80 and above.
What happens when you test Plant Kingdom?
Every chapter test is 25 questions. It starts at moderate difficulty and adapts after each saved answer. If you open a solution before answering, that attempt earns no credit, so your mastery stays honest.
