Mnemonic 1: Underground Stems — "Roger The Brave Captain"

Rhizome (ginger) — Tuber (potato) — Bulb (onion) — Corm (Colocasia)

Memory hook: "Roger The Brave Captain knows the underground."

Mnemonic 2: Seven Families — "Fancy Students Love Making Big Awesome Projects"

• Fabaceae — Solanaceae — Liliaceae — Malvaceae — Brassicaceae — Asteraceae — Poaceae

Mnemonic 3: Placentation — "MAPs go Free to Base"

• Marginal $\frac{pea}{Fabaceae}$ → Axile $\frac{tomato}{Solanaceae}$ → Parietal $\frac{mustard}{Brassicaceae}$ → Free central (Dianthus) → Basal (sunflower/Asteraceae, wheat/Poaceae)

Mnemonic 4: Tissues — "Parce Que Collègues Sont Morts" (French trigger: "because colleagues are dead")

• Parenchyma — Living, thin cellulose walls, storage
• Collenchyma — Living, pectin-corner thickening, flexible
• Sclerenchyma — DEAD, lignin-uniform thickening, rigid

Mnemonic 5: Fabaceae Floral Formula — "Vexillary Dia-delphous Marginal Pod"

V = Vexillary aestivation, D = Diadelphous (9+1), M = Marginal placentation, P = $\frac{Pod}{Legume}$ fruit

Mnemonic 6: Root → Epidermal Layers (inside-out) — "Every Cop Eats Pie, Xylem Phloem"

Epidermis → Cortex → Endodermis (Casparian strip) → Pericycle → Xylem (radial) → Phloem (radial)

Mnemonic 7: Aestivation Types — "VTIV"

Valvate (just touching) → Twisted (one-side overlap) → Imbricate (irregular) → Vexillary (Fabaceae butterfly)

Mnemonic 8: Xylem/Phloem Living Status

"X-rays KILL; Phloem Fibres also die; Sieve Tubes LIVE without brain"

• Xylem vessels, tracheids, fibres = DEAD
• Xylem parenchyma = LIVING
• Phloem fibres = DEAD
• Sieve tubes, companion cells, phloem parenchyma = LIVING
