Many completely dead parts of plants, containing only dead cells, and apparently completely dry, may still long time act as vascular tissue, and if there are not any significant damage, live parts separated by them from the rest of the plant can continue in growth and continue to participate in all plant vital functions, ie primarily photosynthesis and metabolism, also ripenig, if reproductive organs present there.
Maraming ganap na patay na bahagi ng mga halaman, na naglalaman lamang ang mga patay cell, at tila ganap na dry, mahabang panahon ay maaari pa ring kumilos bilang vascular tissue, at kung may mga hindi anumang kapansin-pansing pinsala, live na bahagi na pinaghiwalay ng mga ito mula sa iba pang mga bahagi ng halaman ay maaaring patuloy sa paglago at patuloy upang MAKILAHOK sa lahat ng mga mahalagang mga function ng halaman, ie pangunahing potosintesis at metabolismo, ripenig Gayundin, kung reproductive organo nagpapakita.
