Qhov sib txawv tseem ceeb ntawm lub xov tooj ntawm tes thiab atom yog lub xov tooj ntawm tes yog tsim los ntawm cov molecules whereas atoms ua molecules.
Cells yog qhov ua haujlwm tsawg tshaj plaws hauv cov kab mob uas muaj sia nyob. Nws muaj ntau macromolecules. Lub caij no, atoms tsim cov macromolecules. Yog li, lub atom yog qhov tsawg tshaj plaws ntawm cov teeb meem. Feem ntau, ib lub xovtooj ntawm qhov ntsuas micrometer thaum lub atom nyob hauv qhov ntsuas angstrom.
Cell yog dab tsi?
Ib lub xovtooj yog qhov ua haujlwm tsawg tshaj plaws ntawm cov kab mob nyob. Hauv lwm lo lus, nws yog qhov tsawg tshaj plaws ntawm lub neej. Yog li ntawd, peb hu nws lub tsev thaiv ntawm lub neej. Muaj ntau hom hlwb xws li cov kab mob microorganisms, tsiaj hlwb thiab cov hlwb cog. Lawv muaj cov qauv sib txawv. Tab sis, tag nrho cov hlwb no muaj ib daim nyias nyias uas tuav cov ntsiab lus hauv.
Daim duab 01: Ib Lub Cev Muaj Zog
Thaum xav txog cov qauv ntawm lub xovtooj, nws muaj cov cytoplasm uas muaj cov cell membrane, thiab cytoplasm tuav cov organelles sib txawv xws li mitochondria. Yog li, cov macromolecules sib txawv, xws li cov proteins, nucleic acid, carbohydrates, lipids, thiab lwm yam, ua rau lub hlwb.
Atom yog dab tsi?
Atom yog qhov me tshaj plaws ntawm cov tshuaj lom neeg uas tuaj yeem muaj nyob. Yog li ntawd, nws yog qhov tsawg tshaj plaws ntawm cov teeb meem, thiab ib qho atom sawv cev rau cov khoom ntawm cov tshuaj uas nws belongs. Tag nrho cov roj, cov khoom, cov kua thiab cov ntshav muaj cov atoms. Cov no yog feeb units; feem ntau qhov loj yog nyob ib ncig ntawm 100 picometers.
Daim duab 02: Hom qauv ntawm ib lub Atom
Thaum xav txog cov qauv ntawm ib lub atom, nws muaj cov nucleus thiab electrons txav ib ncig ntawm lub nucleus. Tsis tas li ntawd, protons thiab neutrons (thiab muaj qee qhov subatomic hais ib yam nkaus) ua rau lub atomic nucleus. Feem ntau, tus naj npawb ntawm neutrons, protons thiab electrons yog sib npaug, tab sis nyob rau hauv cov ntaub ntawv ntawm isotopes, tus naj npawb ntawm neutrons txawv ntawm cov protons. Peb hu ob qho tib si protons thiab neutrons "nucleons".
Nyob ib ncig ntawm 99% ntawm lub atom qhov loj yog nyob rau hauv lub nucleus vim hais tias qhov loj ntawm ib tug electron yuav luag negligible. Ntawm cov subatomic hais, ib tug proton muaj +1 nqi; Ib qho hluav taws xob muaj -1 nqi thiab neutron tsis muaj nqi. Yog hais tias lub atom muaj cov zauv sib npaug ntawm protons thiab electrons, ces tag nrho cov nqi ntawm atom yog xoom; tsis muaj ib tug electron ua rau ib tug +1 nqi thiab ib tug nce ntawm ib tug electron muab -1 nqi rau lub atom.
Qhov txawv ntawm Cell thiab Atom yog dab tsi?
Ib lub xovtooj yog ib chav tsev lom neeg, thaum lub atom yog chav tsev tshuaj. Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm lub xov tooj ntawm tes thiab atom yog tias lub xov tooj ntawm tes yog ua los ntawm cov molecules thaum atoms tsim cov molecules. Tsis tas li ntawd, thaum txiav txim siab txog qhov muaj pes tsawg leeg ntawm cov chav no, ib lub xovtooj ntawm tes muaj cytoplasm, cell membrane, nucleus, thiab lwm yam thaum lub atom muaj cov subatomic me me xws li electrons, protons thiab neutrons.
Ntxiv mus, qhov sib txawv ntxiv ntawm cell thiab atom yog tias lub xov tooj ntawm tes muaj macromolecules xws li cov proteins, carbohydrates, lipids thiab nucleic acid thaum molecules yog tsim los ntawm atoms.
Summary – Cell vs Atom
Ib lub xovtooj yog ib chav tsev lom neeg, thaum lub atom yog chav tsev tshuaj. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm lub xov tooj ntawm tes thiab atom yog tias lub xov tooj ntawm tes yog ua los ntawm cov molecules whereas atoms ua molecules.
