Mene ne tsarin da mafi sauki cell? cikakken kwatancin

Kada ka san abin da tsarin a cell ne cikin sauki? Idan ba haka ba, to, wannan labarin ne a gare ku.

Wanne kimiyya karatu keji?

Wannan kimiyya ne ake kira cytology. Yana da wani reshe na ilmin halitta. Ta iya amsa tambaya, abin da yake cikin tsarin da cell protozoa. Har ila yau, wannan nazari na bincika ba kawai tsarin, amma kuma da matakai da faruwa a cikin cell. Wannan salon salula numfasawa, metabolism, haifuwa da kuma photosynthesis. sauki multiplication Hanyar - mai sauki cell division. Wasu na farko Kwayoyin suna iya photosynthesis - samar da kwayoyin halitta daga inorganic. Salula numfasawa faruwa ta tsakiyan nonon mata na glucose. Wannan shi ne babban aikin da sauki carbohydrates a cikin cell. Lokacin da hadawan abu da iskar shaka na cell samun makamashi.

Wane ne cikin sauki?

Kafin akai la'akari da tambaya na yadda tsarin da cell ne mai sauki, bari mu ga abin da suke wadannan "halittun".

Shin kwayoyin cewa kunshi guda cell. Suna kuma kira eukaryotes, tun akwai wani core a cikin kwayoyin jikinsu. Sauki cell ne sosai kama da wani cell a wani kwayar kwayoyin.

rarrabuwa

Akwai shida sauki iri:

• ciliates.
• Radiolaria.
• dory.
• sporozoans.
• sarkozhgutikonostsy.
• flagellates.

Wakilai na farko da irin zauna da gishiri tafkunan. Wasu jinsunan kuma iya rayuwa a cikin ƙasa.

Spore yafi wakilta parasites na vertabrate.

Radiolarians kamar yadda ciliates, rayuwa a cikin teku. Bã su da wani m harsashi sanya na silicon dioxide, wasu daga wanda kankara suna kafa.

Sunfish alama shi ne cewa su motsa tare da taimakon pseudopodia.

Sarkozhgutikonostsy kuma amfani da irin wannan hanyar sufuri. Don irin wannan ne da yawa amoeba da sauran protozoa.

Flagellates wakilta wani bambancin tsararru na kwayoyin, wanda aka yi amfani da motsi na flagella. Wasu jinsunan protozoa iya rayuwa a cikin tafkunan, da kuma wasu masu parasites. Bugu da kari, da yawa 'yan irin wannan ne ba a cikin sel da chloroplast. Wadannan protozoa kansu samar da ake bukata domin rayuwa gina jiki ta hanyar photosynthesis.

Mene ne tsarin da mafi sauki cell?

tsarin tantanin halitta za a iya raba uku main sassa: da jini membrane, cytoplasm da kuma tsakiya. Yawan nuclei a cikin na farko Kwayoyin ne daidai da daya. Wannan shi ne daban-daban daga kwayan Kwayoyin, wanda ba su da nuclei. Saboda haka, bari mu duba a daki-daki, kowane daga cikin uku da aka gyara daga cikin cell.

A jini membrane

Tsarin tantanin halitta na da sauki dole nufa gaban wannan bangaren. Shi ne da alhakin rike da homeostasis na cell, kare shi daga muhalli da tasirinsa. A jini membrane kunshi uku azuzuwan na lipids: phospholipids, glycolipids da cholesterol. Fi yawa a cikin tsarin da membrane phospholipids.

A cytoplasm ne: yadda yake aiki?

Wannan shi ne duk da cewa wani bangare na kwayar halitta, fãce da tsakiya, wanda shi ne a cikin jini membrane. Ya kunshi hyaloplasm da wasu gabbansa, kuma inclusions. Hyaloplasm - ne ciki yanayi na cell. Wasu gabbansa ne m Tsarin cewa yin takamaiman ayyuka, kamar yadda shi ne hada da wadanda ba na dindindin Tsarin cewa yin yafi ga stock zaɓi.

A tsarin da na farko Kwayoyin: wasu gabbansa

A cikin cell, da mere gaban da yawa wasu gabbansa, wanda suke peculiar zuwa dabba Kwayoyin. Bugu da kari, da bambanci ga Kwayoyin na kwayar kwayoyin, mafi daga cikin sel da wasu gabbansa sauki ƙungiyoyi - kowane irin flagella, cilia da kuma da sauran fannin jiki. A gaban irin wannan tsarin zai iya gadara da sosai 'yan sel kwayar dabbobi - kawai cikin maniyyin ba.

By da wasu gabbansa da suke ba a cikin sel da sauki ne mitochondria, ribosomes, lysosomes, endoplasmic reticulum, Golgi hadaddun. Kwayoyin suna ma wasu na farko chloroplast, waxanda suke da halayyar shuka Kwayoyin. A sifa da aiki kowane daga cikinsu a cikin tebur.

Bugu da kari, da Kwayoyin suna bayar da sauki ƙungiyoyi da wasu gabbansa. Wannan na iya zama flagella da cilia. Dangane da nau'in, jiki zai iya suna da duka guda kuma mahara flagella.
