Mbewu zimayamwa zakudya m'njira ziwiri: kuyamwa kwa mizu ndi kuyamwa masamba. Kuyamwitsa kwa mizu kumaphatikizapo kuthira feteleza m'nthaka, pomwe amakumana ndi mizu ndikuyamwa ndikugwiritsidwa ntchito ndi mizu yabwino kapena nsonga za mizu, kenako amatumizidwa ku mizu, tsinde, masamba, maluwa, ndi zipatso za mbewu.

Izi zimagwiritsidwa ntchito kulimbikitsa kugawanika kwa maselo a zipatso kapena kutalika, kuonjezera chiwerengero cha zipatso ndi kulemera kwa zipatso. Amagwiritsidwa ntchito kwambiri popanga zipatso monga mphesa, sitiroberi, ndi maapulo.

mitengo ya ubber ndi mitengo italiitali yokhala ndi moyo wachuma kwa zaka makumi angapo, ndipo latex yake imakololedwa pogogoda makungwa, njira yapadera yokolola. Labala amapangidwa kuchokera ku minyewa yomwe imapanga latex mu khungwa la mtengo wa rabala. Maselo a latex amagwiritsa ntchito zinthu zopangidwa ndi photosynthesis—shuga ndi zakudya zina—kuti apange mphira popanga zinthu zosiyanasiyana.
