Monotropa merupakan Angiospermae yang tidak berkolofil sehingga tidak mampu untuk melakukan fotosintesis. Monotropa mendapatkan nutrisi untuk pertumbuhan dan perkembangannya melalui mekanisme miko-heterotrof, yaitu dengan berasosiasi dengan jamur mikoriza. Mikoriza bersimbiosis dengan akar tumbuhan autotrof untuk mendapatkan hasil fotosintesis, nutrisi tersebut kemudian ditransfer ke tumbuhan Monotropa. Sel-sel hifa yang berhubungan dengan epidermis akar tumbuhan autotrof dan Monotropa merupakan titik transfer nutrisi. Hifa mikoriza akan membentuk selubung (sheath) ke akar tumbuhan yang kemudian akan membentuk struktur hartig net yang menembus epidermis akar. Hartig net akan terus mengintrusi ke sel korteks akar yang kemudian akan membentuk fungal pegs. Fungal pegs ini yang akan menginduksi terbentuknya transfer sel untuk mentransfer nutrisi dari mikoriza ke Monotropa
