Ka sehloohong dimela dinama tse nyenyane tse: tlhaloso e feletseng ea

Masela a - ka sebopeho nang le e plurality lisele tse tšoanang tse nang le mesebetsi e tloaelehileng. Liphoofolo tsohle tse multicellular le dimela (ho sa ballwe dimelametsing) bopilwe mefuta e fapaneng ya dinama tse nyenyane tse.

ke eng lesela?

Ka lisele phoofolo li arotsoe ka mefuta e 'nè:

• epithelial;
• mesifa;
• dikgokelo;
• tšohile dinama tse nyenyane tse.

Kaofela ha tsona, ntle le bakeng sa ea methapo ea kutlo, le arohaneng le eena ka mefuta. Kahoo, epithelium ka ba dikhubu, bataletseng, cylindrical, ciliated le hlokolosi. Muscle dinama tse nyenyane tse e arotsoe striated, cardiac le boreleli. The Group na le mafura connective, teteaneng fibrous, faeba hlephileng, reticular, lesapo le lefufuru, mali le lisele tsa mmele.

Dimela lisele le mefuta e ana:

• thuto;
• conductive;
• barbotage;
• phetha molao dinama tse nyenyane tse;
• excretory (secretory);
• dinama tse nyenyane tse ipatileng (parenchyma).

Kaofela ha bona ba arotsoe ka lihlopha-potlana. Ho joalo, bakeng sa lisele thuto tse bolaeang, e kenellang lipakeng, lehlakoreng le leqeba. Conductive arotsoe ka ho xylem le phloem. Koahela masela kopana mefuta e meraro: ho epidermis, diporopo le Cork. Manual e arotsoe collenchyma le sclerenchyma. Secretory dinama tse nyenyane tse e arotsoe mefuta. A ka sehloohong dimela dinama tse nyenyane tse, joaloka batho ba bang kaofela, e ba 'maloa mefuta. A re hlahlobeng bona ka ho qaqileng.

ke eng e ka sehloohong dimela dinama tse nyenyane tse?

Ho na le tse 'nè tsa mefuta e oa hae. Kahoo, lesela ka sehloohong ke ho re:

• aquifer;
• pneumatici;
• assimilation;
• Stock tsoha.

Ba na le mohaho o tšoanang, empa ba bang ba se tšoane le e mong le tse ling. Mosebetsi o ka sehloohong oa tsena le mefuta e mene ea lisele le batla le fapaneng hape.

Sebōpeho sa lesela: a kakaretso kakaretso

Lesela motheo ea mefuta eohle e mene e entsoe ka lisele tse phelang e nang le marako a masesaane. Masela a ba mofuta ona ba e le bitsoa hobane ba motheong oa litho tsa 'ohle. Joale a re sheba mesebetsi le sebopeho sa lesela motheo ea e mong le e mofuta bomong ka ho qaqileng le ho feta.

Metsi behang dinama tse nyenyane tse: sebopeho le mosebetsi

Lesela ka sehloohong ea mofuta ona e hahoa lisele tse kgolo na mabota mosesaane. Ka vacuoles ea lisele tsa dinama tse nyenyane tse mucous na le ntho e khethehileng, e leng e reretsoe ho boloka mongobo.

Mesebetsi aquifer lesela itšetlehile ka 'nete ea hore ho boloka mongobo.

Ke metsi behang parenchyma ka bakoa le makhasi ea limela tse kang cacti, lekhala, lekhala, 'me a mang, ho hōla a leholimo omeletseng. Ka lebaka la ho ba bangata ba joalo dimela dinama tse nyenyane tse ka Stock ka ka metsi a ka tabeng ea pula ke ke ba nako e telele.

Features pneumatici parenchyma

dinama tse nyenyane tse ipatileng lisele tsa mefuta e sa ba le hōle le e mong le tse ling. Ka pakeng tsa ba libaka tse intercellular oo moea e boloketsoe.

Ho sebetsa ha parenchyma ke hore ho fana ka lisele tsa lisele tse ling tsa dimela le carbon dioxide le oksijene.

Ho na le ke dinama tse nyenyane tse joalo 'meleng hangata ka Marsh le dimela tsa metsing. Naheng e sa tloaelehang.

Assimilative parenchyma: sebopeho le mosebetsi

Ho na le e mahareng-boholo bo lekaneng lisele tse tšesaane-marako.

Ka hare ka seleng assimilation dinama tse nyenyane tse ka bongata ke chloroplasts - the organelles le boikarabelo ba ho tala.

organelles tsena na lera tse pedi. Ka hare ho thylakoids chloroplast di - mekotla discoid tsa enzyme leng ho 'ona. Ba bokelloa ka liqubu - grana. Recent ya kokangana ke lamellar - o molelele o dibopeho tšoanang le thylakoids ena. Ho feta moo, chloroplasts ke starch inclusions ribosome hlokahala hore tswakana tsa protheine, DNA le RNA saeteng.

Tshebetso ya tala - generating dintho manyolo ho tloha inorganic ke enzyme le matla a letsatsi - o hlahellang teng thylakoids. The potlakisang tsebetso ea lik'hemik'hale ka sehloohong eo e fana ka liphetoho tsena lik'hemik'hale o bitsoa chlorophyll. ntho ena ke tala (leboha ho eena makhasi 'me re susumetsoa tsa dimela ba le' mala o ena).

Ho joalo, mosebetsi o ka sehloohong oa ea mofuta ona e dinama tse nyenyane tse - tala e boletsoeng ka holimo, hammoho le phapanyetsano khase.

Assimilation dinama tse nyenyane tse e ngata tse tsoetseng pele ka ho makhasi le ka holimo bakoa ea limela herbaceous. e boetse teng litholoana tala. Assimilation dinama tse nyenyane tse e sa ka holim 'a makhasi' me re susumetsoa, le sebeletsang pepeneneng letlalo sireletsang.

Features polokelo parenchyma

Lisele tsa lisele ena ba tšoauoa ka boholo mahareng. mabota a bona ke tloaelo ho tšesaane, empa e ka thatafetseng.

Mosebetsi polokelo parenchyma - polokelo ya limatlafatsi. Ka lebaka leo, maemong a mangata, ho sebeletsa e le starch, inulin, le lik'habohaedreite tse ling, 'me ka linako tse ling - lihaha-'mele,-amino acid le mafura.

Ke lesela la mofuta ona ka embryos ya dipeo tsa dimela tsa selemo le selemo, hammoho le ho endosperm ena. Ka perennial litlama, lihlahla, lipalesa le lifate tse ho boloka lesela ka 'na ea bulbs ka, tubers, metso, hammoho le ka ea mantlha ea bakoang le.

bofello

Lesela ka sehloohong - bohlokoa ka ho fetisisa 'meleng oa semela, kaha e ke ka lebaka la makala tsohle. Masela tsa mofuta ona fana dithulaganyo ka 'ohle, ho akarelletsa le tse tala le phapanyetsano khase. Hape, lisele tsa motheo le boikarabelo ba ho bōpa bososoli ya dintho manyolo (ho le ngata ka ho fetisisa ke starch) ka dimela la bona, empa hape le ka dipeo tsa bona. Ho feta moo phepo metsoako manyolo ka parenchyma le ka li sirelelitsoe moeeng le metsi. Pneumatici le lisele tse metsi behang na hase bohle ba limela. Eo hona joale e pele feela lehoatateng, 'me ea bobeli - ka mefuta makgobokgobo.
