Plant Kingdom is short, fact-based and very predictable. This plant kingdom NEET PYQ analysis breaks down the question types NTA repeats, the pigment and food-storage tables you must know cold, and the examples that keep appearing in past papers.

Why Plant Kingdom Deserves Your Time
NEET usually asks one to two questions from Plant Kingdom. Almost every question is a direct NCERT line: a pigment, a stored food, an example or a feature. You can master the chapter in a few focused sessions. For a strategy on where this chapter fits in your revision, see the NEET 2027 chapter weightage.
Many of these facts also come back as statement-based questions. Our guide to assertion reason question tricks helps with that format.
Plant Kingdom NEET PYQ Analysis: What NTA Repeats
When you sort a decade of NEET biology PYQs from this chapter, four question types cover nearly everything.
| Question type | Frequency | What it tests |
|---|---|---|
| Algae groups | Most frequent | Pigments, stored food, cell wall, examples |
| Bryophytes vs pteridophytes | Very frequent | Dominant phase, heterospory, vascular tissue |
| Naked-seed plants | Regular | Coralloid roots, mycorrhiza, naked seeds |
| Economic importance | Regular | Agar, algin, carrageen, peat, protein-rich algae |
The algae table alone accounts for a large share of questions. Our list of overlooked NCERT Botany lines covers the small facts that trip students up here. For a quick warm-up before the full set, try these five quick Plant Kingdom questions.
Algae Classes: The Table You Must Memorise
| Feature | Chlorophyceae (green) | Phaeophyceae (brown) | Rhodophyceae (red) |
|---|---|---|---|
| Main pigments | Chlorophyll a, b | Chlorophyll a, c, fucoxanthin | Chlorophyll a, d, phycoerythrin |
| Stored food | Starch | Laminarin, mannitol | Floridean starch |
| Examples | Chlamydomonas, Volvox, Spirogyra, Chara | Ectocarpus, Laminaria, Sargassum, Fucus | Polysiphonia, Porphyra, Gracilaria, Gelidium |
Economic facts NTA asks often:
- Agar comes from Gelidium and Gracilaria
- Algin comes from brown algae, and carrageen from red algae
- Chlorella is a unicellular, protein-rich alga used as a food supplement
Bryophytes and Pteridophytes
Bryophytes and pteridophytes are often tested side by side. To track which of facts like these are asked repeatedly, compare with our most repeated NEET topics list.
| Feature | Bryophytes | Pteridophytes |
|---|---|---|
| Dominant phase | Gametophyte | Sporophyte |
| Vascular tissue | Absent | Present (first vascular plants) |
| Examples | Marchantia, Funaria, Sphagnum | Selaginella, Equisetum, Dryopteris, Pteris |
Key facts: bryophytes are called the “amphibians of the plant kingdom”. Sphagnum provides peat. Selaginella and Salvinia are heterosporous, which NCERT describes as a precursor to the seed habit.
Gymnosperms
These plants have naked ovules, which means the seeds are not enclosed in a fruit. Two root facts are asked often:
- Cycas has coralloid roots associated with nitrogen-fixing cyanobacteria
- Pinus roots have fungal associations called mycorrhiza
Sequoia, a gymnosperm, is one of the tallest tree species. Ginkgo and Cycas are other common examples.
Worked PYQ-Pattern Questions
Q1. Floridean starch is the stored food of: (a) Chlorophyceae (b) Phaeophyceae (c) Rhodophyceae (d) Cyanobacteria
Answer: (c) Rhodophyceae. Red algae store floridean starch, which is similar to amylopectin and glycogen.
Q2. Which plant is heterosporous? (a) Funaria (b) Selaginella (c) Marchantia (d) Dryopteris
Answer: (b) Selaginella. Salvinia is the other NCERT example.
Q3. Agar is obtained from:
Answer: Gelidium and Gracilaria, both red algae.
Q4. The dominant phase in the life of a moss is the:
Answer: Gametophyte. In bryophytes the sporophyte depends on the gametophyte.
Common Traps in This Chapter
- Mixing up chlorophyll c (brown algae) and chlorophyll d (red algae)
- Saying bryophytes have vascular tissue
- Calling Dryopteris heterosporous (it is homosporous)
- Linking algin with red algae instead of brown algae
- Forgetting that coralloid roots belong to Cycas, not Pinus
