Botany Labs

Interactive botany, built for NEET. Rotate it, test yourself, remember it.

Molecular Basis of Inheritance

2 labs
Genetics & EvolutionMedium3D

Nucleosome

See how 2 metres of DNA folds into a 10 µm nucleus. Explore the nucleosome in 3D — click the 8 histones (2 each of H2A, H2B, H3, H4), the DNA wrapped 1.65 turns, and the H1 linker. Then switch to DNA Packing and coil the 'beads on a string' into the 30 nm chromatin fibre, watching the packing ratio climb.

DNA Packaging

Drag one slider and watch 2 metres of DNA fold all the way down to a 10,000× compacted chromosome. Walk the five packing levels in 3D — naked double helix → nucleosomes (beads-on-a-string) → 30 nm chromatin fibre → looped domains → the condensed metaphase chromosome — with the packing ratio climbing 1× → ~10,000× at every step.

Cell: The Unit of Life

Cell BiologyEasy3D

Prokaryotic Cell

Explore a bacterial cell in 3D cutaway. Click the capsule, cell wall, plasma membrane, mesosome, nucleoid, plasmid, 70S ribosomes, flagella and pili to learn NEET-relevant facts. Flip the Gram Stain toggle to watch the wall thicken and the outer membrane appear — Gram +ve vs Gram −ve, seen not memorised.

Marchantia

Explore the dorsiventral thallus of Marchantia in 3D — a classic NEET liverwort. Click the green dorsal surface (diamond air chambers + gemma cups), flip to the pale ventral side (rhizoids + scales), and study the two gametophores: the scalloped ♂ antheridiophore and the finger-lobed ♀ archegoniophore.

Photosynthesis in Higher Plants

Light Reaction 3D

Ek electron pair ko paani se NADPH tak follow karo — live. Stepper ghumao aur dekho PSII (P680) photon kaise pakadta hai, paani lumen mein kaise phatta hai, aur H⁺ ions kaise andar jama hote hain. Side mein Z-scheme diagram same stop pe sync chalta hai, energy axis ke saath — ab wo zigzag doodle nahi, mechanism hai. Cyclic vs non-cyclic toggle dabao aur turant dekho ki ATP-only vs ATP+NADPH+O₂ ka fark kahan se aata hai.

Cell Cycle and Cell Division

Genetics & EvolutionMedium3D

Crossing Over

Prophase I ke paanch stages ek ek karke dekho — synapsis, synaptonemal complex, pachytene mein crossing over, diplotene ke chiasmata — sab 3D mein, stepper se. Maternal homologue teal, paternal violet; crossing-over toggle off karke dekho: saare gametes parental ho jaate hain, par phir bhi do alag classes bachti hain (har class do baar) — kyunki independent assortment apna kaam khud karti hai. Crossing over ON karo aur dekho recombinant chromatids — combos jo kisi parent ke paas nahi the. Anaphase I vs anaphase II ka confusion yaha permanently clear ho jaayega: pehle homologues alag, sisters baad mein.

Anatomy of Flowering Plants

Monocot vs Dicot Anatomy

Chaaron flat diagrams (dicot stem, monocot stem, dicot root, monocot root) ko ratt-ne ka band karo. Yaha ek real 3D organ khada hai — usse ghumao, slicing slider se cut plane ghumaao, aur textbook wali T.S. diagram cut face par khud ban'ti dikhegi. Xylem har state mein orange hai, isliye chaaron diagrams ek system lagne lagte hain. Neeche labelled SVG T.S. aur 'isse pehchano' tells milenge jo revision ke liye kaafi hain.

Placentation 3D

Paanch placentation types ratna band karo — unhe KAATO. Ek 3D ovary rotate karo, slice slider se beech se kaato, aur dekho ki textbook wala circle khud ban jaata hai. Marginal, axile, parietal, free-central, basal — har type ka asli 3D difference dikhega: kitne chambers, ovules kahan chipke hain, septa hain ya nahi. Sibling T.S. diagram same state se sync mein draw hota hai, toh revision ke liye exact NCERT figure ready milegi.

Sexual Reproduction in Flowering Plants

1 lab
ReproductionHard3D

Double Fertilisation

Sab kehte hain 'fertilisation matlab ek sperm + ek egg' — angiosperms mein nahi hota aisa. Ek pollen tube DO male gametes girata hai: ek egg se fuse hoke zygote (2n) banata hai, doosra do polar nuclei ke saath triple fusion karke PEN (3n) banata hai. Is 3D lab mein stepper ghumao — mature 7-celled, 8-nucleate embryo sac se lekar dono fusions tak — aur har structure pe floating ploidy tag dekho. Counting khud aankhon se hogi, ratta nahi lagana padega.

Transport in Plants

Plant PhysiologyMedium3D

Transpiration Pull

Sab bolte hain 'root pressure paani ko upar dhakelta hai' — galat. Is lab mein ek tree-height ka straw dekho: leaf se evaporation ek molecule le jaati hai, cohesion agle ko kheenchta hai, aur poora orange water column ek dhaage ki tarah upar chadhta hai. K⁺ influx toggle dabao aur guard cells ka pore khud khulta hai — K⁺ in → paani follow → turgid → moti inner wall bow karti hai. Cohesion toggle off karo aur column cavitate hoke toot jaata hai. Ψ gradient root → leaf live girta dikhega.
