<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Kupfuura: Phloem inyanzvi inoshandiswa kutakura zvokudya muzvirimwa zvepamusoro, kunyanya kutakura sucrose nepamusoro pemhepo inokonzerwa neosmosis, nzira inonzi translocation. Phloem ivhu rakaoma kunzwisisa, rinoumbwa nemhando mbiri huru dzemasero, machubhu esiringi nemasero anowirirana zvikuru, pamwe chete nemasero eparenchyma, maploem fibers uye sclereids. Mapaipi etsinga akabatanidzwa kubva kumagumo kusvika kumagumo nemapureti emagumo pakati peanozivikanwa semapureti etsinga, ayo anobvumira kutakurwa kwephotosynthate pakati pezvinhu zvetsinga. Zvikamu zvetubhu rezefa hazvina nyukliya uye ribosomes, uye metabolism yazvo nemabasa zvinodzorwa nemasero anoperekedza nucleate. Masero anowirirana, akabatanidzwa kumapaipi anosefa kupfurikidza neplasmodesmata, ane mutoro wokutakura phloem neshuga. Mabryophytes haana phloem, asi moss sporophytes ane nhengo dzisina kuoma dzine basa rakafanana rinozivikanwa se leptome. Mubvunzo: Chii chinonzi leptome?  <response>: nhengo dzisinganyanyi kuoma dzine basa rakafanana
