Cov cell phab ntsa, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, thiab ribosomes yooj yim pom nyob rau hauv no kis tau tus mob. electron micrograph . (Courtesy ntawm Brian Gunning.)

Ua raws li qhov kev pom no, dab tsi tuaj yeem pom nrog lub tshuab ntsuas hluav taws xob?

Electron microscopes yog siv los soj ntsuam ultrastructure ntawm ib tug ntau yam ntawm lom thiab inorganic specimens nrog rau cov kab mob, cell, loj molecules, biopsy kuaj, hlau, thiab crystals. Kev lag luam, electron microscopes feem ntau yog siv rau kev tswj kom zoo thiab tsis ua hauj lwm tsom xam.

Ib sab saum toj no, hom microscope tuaj yeem pom cov hlwb? Compound microscopes yog teeb illuminated. Daim duab pom nrog lub tshuab ntsuas no yog ob sab. Qhov no microscope yog feem ntau siv. Koj tuaj yeem saib cov hlwb ntawm tus kheej, txawm tias muaj sia nyob.

Ib yam li ntawd ib tug yuav nug, cov qauv ntawm tes tuaj yeem pom tsuas yog nrog lub tshuab ntsuas hluav taws xob?

Ribosomes

Electron microscopes puas tuaj yeem pom cov cell nyob?

Electron microscopes yog cov cuab yeej muaj zog heev rau kev pom cov qauv lom neeg. Lawv pab cov kws tshawb fawb saib cov hlwb , cov ntaub so ntswg thiab cov kab mob me me hauv kev nthuav dav heev. Txawm li cas los xij, cov qauv tshuaj lom neeg no ua tau 'tsis raug saib rau electron microscopes thaum tseem ciaj sia.
