Anatomy of Flowering Plants carries 4.5 of 100 Botany marks in NEET by past-paper share: 36 of the 793 tagged NEET Botany PYQs in the ViJEEta bank (NEET 2013–2026). It ranks 11 of 21 Botany chapters.
How the weight is computed: this chapter's tagged NEET PYQs divided by all tagged NEET Botany PYQs in the bank (36 of 793), times 100, with repeated questions counted once. The bank does not store the year of each NEET question, so none is printed. Computed from the bank at build time. Updated 19 Oct 2026.
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.
Three tissue systems by structure and location: epidermal, ground (fundamental) and vascular (conducting).
Asked as: match tissue system with its component (e.g. pericycle ground, trichome epidermal).
Epidermis is usually one layer of parenchyma cells with a large vacuole; the waxy cuticle cuts water loss but is absent in roots.
Asked as: "Cuticle is absent in: leaf / stem / root / fruit".
Guard cells are bean-shaped (dumb-bell shaped in grasses), contain chloroplasts, and have thin outer walls but highly thickened inner walls facing the pore.
Asked as: which wall of the guard cell is thickened, or the shape of guard cells in grasses.
Stomatal apparatus stomatal aperture guard cells subsidiary cells (specialised epidermal cells next to the guard cells).
Asked as: "Which is NOT part of stomatal apparatus?"
Root hairs are unicellular; shoot trichomes are usually multicellular, branched or unbranched, sometimes secretory, and reduce transpiration loss.
Asked as: root hair vs trichome, unicellular vs multicellular statement pairs.
Ground tissue is every tissue except epidermis and vascular bundles (parenchyma, collenchyma, sclerenchyma); in leaves it is the chloroplast-rich mesophyll.
Asked as: "Ground tissue includes all EXCEPT…"
Open bundle has cambium between xylem and phloem (dicot stem); closed has none (monocots). Radial xylem and phloem on alternate radii (roots); conjoint same radius (stems, leaves), phloem usually outside xylem.
Asked as: match bundle type with organ / plant group.
Dicot root (sunflower): endodermis is one layer of barrel-shaped cells, no intercellular spaces, with suberin casparian strips on tangential and radial walls.
Asked as: chemical nature of casparian strips (suberin) and which walls carry them.
Pericycle (thick-walled parenchyma) gives rise to lateral roots and to vascular cambium in secondary growth.
Asked as: "Lateral roots arise from: endodermis / pericycle / cortex / epiblema".
Dicot root: – xylem and phloem patches, small pith, conjunctive tissue between xylem and phloem; stele everything inside the endodermis.
Asked as: define conjunctive tissue / stele; diarch–tetrarch identification.
Monocot root: polyarch (usually more than six xylem bundles), large well-developed pith, no secondary growth.
Asked as: T.S. with many xylem bundles and big pith monocot root.
Dicot stem cortex: collenchymatous hypodermis, parenchyma middle, endodermis rich in starch (starch sheath); pericycle as semi-lunar sclerenchyma patches above phloem.
Asked as: "Starch sheath in dicot stem is the…" (endodermis).
Dicot stem bundles: arranged in a ring, conjoint, open, endarch protoxylem; medullary rays between bundles; large parenchymatous pith.
Asked as: ring arrangement endarch identify dicot stem.
Monocot stem: sclerenchymatous hypodermis, scattered conjoint closed bundles each with a sclerenchymatous bundle sheath, peripheral bundles smaller than central ones, no phloem parenchyma, water-containing cavities present.
Asked as: NCERT exercise: "conjoint, scattered, sclerenchymatous sheath, no phloem parenchyma ?"
Dorsiventral (dicot) leaf: abaxial (lower) epidermis has more stomata; palisade (elongated, vertical) on adaxial side, spongy (loose, air spaces) below; bundles surrounded by thick-walled bundle sheath; reticulate venation.
Asked as: adaxial vs abaxial position of palisade and stomata.
Isobilateral (monocot) leaf: stomata on both surfaces, mesophyll not split into palisade and spongy; in grasses, adaxial bulliform cells along veins go flaccid under water stress and curl the leaf inward.
Asked as: function and location of bulliform cells.
Hypodermis flips between the two stems. Dicot stem hypodermis is collenchyma, monocot stem hypodermis is sclerenchyma. And the endodermis is the starch sheath in the dicot stem but the casparian-strip layer in the root.

Unknown is not zero. Until you answer at least 3 graded questions in Anatomy of Flowering Plants, 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.
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.
