Chirimwa rinenge uye tsanangudzo pfupi

Dyarai munyama zvikuru siyana. Sezvineiwo, morphological zvechadenga nechimwe chacho kunobva zvakananga ayo executable mabasa. It vakasarudza govera vamwe vavo mhando:

• dzidzo;
• bemhapemha;
• zvemaziso;
• conductive;
• zvinokosha.

mamiriro nomumwe ane mamwe features, izvo dzichakurukurwa pazasi.

Educational chirimwa tishu

Educational zvinyama vanonzi meristems. mamiriro ichi chine duku, polyhedral masero pamwe matete masvingo. Vari kuvharwa zvakasimba pamwe chete. Pasi maikorosikopu unogona kuona kuti ivo vane hombe neerekitironi vacuoles duku zhinji. A chinokosha rejira iri kukwanisa masero ayo agovane ichi-. Izvi ndizvo zvinoita kugara ikure chirimwa. It vakasarudza govera marudzi anotevera:

• Primary meristem - chirimwa vakura jira ichi anochengeterwa mazano matavi uye mudzi mazano. Voitakura kunze nemhaka yake chikuru chirimwa kukura pakureba.
• Secondary meristem - cambium kukurukurwa uye fellogenom. micheka izvi zvinopa kuwanda wechipiri hunde uye mudzi dhayamita. By nzvimbo dzoga apical, lateral uye yechipiri intercalary meristem.

Bemhapemha chirimwa tishu

The pabutiro jira anoiswa pamusoro muviri pechiso chirimwa. Its chikuru basa - ndiyo dziviriro. Zvivako kwakadaro mhosva nemishonga zvinomera kuti zvokuimba kushushikana, kudzivirira pamusoro nokukurumidza tembiricha kuchinja uye kunyanya kwemvura ine mwando, kudzivirira pamusoro ingress kuti utachiona. Nhengo pabutiro inogona kupatsanurwa muzvikwata mikuru mitatu:

• Epiderme e (ganda) - ndiro rinenge chikuru kuti chinosanganisira diki, yakajeka, uye zvakasimba yakavharwa pakati masero. Kazhinji, izvi mhando rejira vakafukidza mashizha uye vaduku matavi. The epidermal rukoko mashizha rinosanganisira stomata - inotungamirwa zviri kukonzera dzinotsanagura gasi Exchange uye transpiration.
• Periderm - dzisiri unhani rejira, iyo anoiswa pamusoro hunde uye mudzi pamusoro. Inoitwa feloggena uye koko. Cork chinhu akafa muchitokisi layer masvingo ayo akaiswa mushonga wokuuraya mvura isapinda fuma suberin.
• Cork - rinenge riri chinoratidza miti uye mamwe makwenzi ose. rukoko urwu kufukidza zvinyama ndiyo kwokunze chikamu chimiso.

Kuitisa munyama zvinomera

The chikuru basa boka iri munyama - chokufambisa mvura uye zvicherwa kune muviri chirimwa. Kusiyanisa pakati zvinotevera mhando conductive zvinhu:

• Xylem - kunoita mvura pamwe ichiputswa zvicherwa kubva pamudzi pasi zvikamu chirimwa. It ine mudziyo unokosha, inonzi trachea uye tracheids.
• Phloem - chinokosha, chinopa pamusoro-pasi ano. Kuburikidza nesefa sepombi zvose Organic zvinovaka muviri, izvo synthesized ne mashizha kupararira dzimwe nhengo dzose chirimwa, kusanganisira midzi.

Mucheka chikuru zvinomera: parenchyma

jira ichi rinoumbwa diki zvipenyu masero pamwe matete masvingo. Kuti hwaro ose nhengo. Zvinosanganisira:

• Kuitwa rinenge - dzine masero akawanda uye chloroplasts ndivo anokonzera dzinotsanagura photosynthesis uye paumbwe Organic zvinhu. Vazhinji munyama izvi zviri mashizha.
• Storage munyama - masero vari rakachengetedzwa muviri. zvinyama iri kusimbiswa zvibereko, midzi uye mbeu.
• Water inobereka rinenge - inoshandiswa kuunganidza uye kuchengetedzwa mvura. Izvi zvinyama hunhu miti kurarama inopisa uye akaoma mumamirire ekunze, akadai mukonde.
• jira Pneumatic - Micheka akadaro yakakura intercellular in ayo akazara mumhepo. Aerenchyma maitiro nomumachakwi uye hwemvura zvirimwa.

Zvokuimba chirimwa tishu

Anokonzera nokuumba simba puranga. Vanotsigira chimiro chirimwa, zvichiita zvakawanda nemishonga zvokuimba simba. Inoitwa rejira zvakadaro gobvu matehwe masero. Zvikuru pakufamba zvokuimba zvinyama muhurukuro hunde yacho chirimwa.
