Chiyambi

Mu thupi la zomera, pali mitundu ingapo ya minofu. Awiri ofunikira kwambiri ndi parenchyma ndi collenchyma. Ngakhale kuti zonsezi zimagwira ntchito zofunika pa zomera, zimakhala ndi makhalidwe ndi ntchito zosiyanasiyana.

Parenchyma

Parenchyma ndi minofu ya zomera yomwe imapezeka mu ziwalo zonse za zomera. Zimapanga zambiri za thupi la zomera ndipo zimapangidwa ndi maselo omwe ali ndi makoma ochepa komanso osasiyanitsidwa bwino. Ntchito yake yayikulu ndikupanga njira zosiyanasiyana za metabolic, monga photosynthesis, kupuma kwa ma cell ndi kaphatikizidwe ka zinthu zosungidwa.

Mitundu ya parenchyma

  • Chlorophyllous parenchyma: Imayambitsa photosynthesis. Amapezeka mu ziwalo zobiriwira za zomera, monga masamba, zimayambira zobiriwira ndi zipatso zosapsa.
  • Reserve parenchyma: Kusunga zakudya m'chomera, monga zowuma kapena lipids. Zimapezeka mumbewu ndi ziwalo zosungira.
  • Hereferous parenchyma: Imasunga madzi muzomera zomwe zimakhala m'madzi kapena m'malo achinyezi kwambiri.

Colenchyma

Collenchyma ndi minofu ya zomera yomwe imapangidwa ndi ma cell omwe ali ndi makoma okhuthala komanso makulidwe osakhazikika. Zimapezeka mu ziwalo zomwe zikukula, monga timitengo tating'ono, ndipo zimapanga zosanjikiza zomwe zimapereka chithandizo ku chomeracho. Zitha kupezekanso m'masamba ndi maluwa ndipo ntchito yake ndikupereka kukhazikika komanso kuthandizira chomera.

Zapadera - Dinani apa  Mitengo yokhala ndi golide: sayansi, tizilombo tating'onoting'ono, ndi kufufuza kosabowola

Kusiyana pakati pa parenchyma ndi collenchyma

  • Maselo a parenchyma ali ndi makoma opyapyala, osasiyanitsidwa bwino, pomwe ma cell a collenchyma amakhala ndi makoma okhuthala, osakhazikika bwino.
  • Parenchyma imapezeka mu ziwalo zonse za zomera, pamene collenchyma imapezeka mu ziwalo zomwe zimakula.
  • The parenchyma imapanga kagayidwe kachakudya, pomwe collenchyma imapereka chithandizo ndi kuuma kwa mbewu.

Mapeto

Ngakhale parenchyma ndi collenchyma ndizosiyana malinga ndi mapangidwe awo ndi ntchito zawo, zonsezi ndizofunikira pa moyo wa zomera. Parenchyma imagwira ntchito yofunika kwambiri ya kagayidwe kachakudya, pomwe collenchyma imathandizira ndikuumirira kuti igwire. ntchito zake molondola.
