Key Difference – Anisogamy vs Isogamy vs Oogamy
Kev sib deev yog ib hom kev yug me nyuam uas muaj ob lub hlwb sib txawv hu ua gametes fused los tsim ib lub diploid zygote uas txuas ntxiv mus rau cov xeeb ntxwv. Kev sib xyaw ntawm txiv neej thiab poj niam gametes thaum lub sij hawm kev sib deev yog hu ua syngamy. Syngamy txawv ntawm cov kab mob raws li qhov xwm ntawm gametes thiab lawv hom fusion. Muaj peb hom syngamy hu ua anisogamy, isogamy thiab oogamy. Isogamy yog fusion ntawm ob lub motile gametes uas yog morphologically zoo tib yam thiab physiologically txawv. Anisogamy yog fusion ntawm morphologically dissimilar txiv neej thiab poj niam gametes uas yuav ua tau motile los yog immotile. Oogamy yog ib daim ntawv ntawm anisogamy uas fusion ntawm immotile, loj poj niam gamete (qe) tshwm sim nrog motile, me me txiv neej gamete (sperm). Qhov no yog qhov sib txawv tseem ceeb ntawm anisogamy isogamy thiab oogamy.
Anisogamy yog dab tsi?
Yog syngamy tshwm sim ntawm ob tug txiv neej thiab poj niam sib txawv gametes, nws yog hu ua anisogamy lossis heterogamy. Hauv anisogamy, txiv neej thiab poj niam gametes tuaj yeem sib txawv raws li cov phev thiab qe. Ob gametes yog motile hauv qee hom thaum tsuas yog txiv neej gamete yog motile hauv qee yam kab mob. Poj niam gamete yog qhov loj me dua li txiv neej gamete. Hauv qee yam kab mob, tus poj niam gamete tsis muaj flagella txav. Li no, txiv neej gamete txav mus rau poj niam gamete rau syngamy. Anisogamy tau pom los ntawm cov nroj tsuag qis xws li qee cov algae ntsuab thiab liab algae.

Isogamy yog dab tsi?
Lub fusion ntawm morphologically zoo sib xws tab sis physiologically dissimilar ob gametes hu ua isogamy. Tsis muaj qhov sib txawv ntawm poj niam gametes thiab txiv neej gametes hauv isogamy. Lawv raug xa mus rau qhov zoo (+) thiab tsis zoo (-) mating hom. Ob gametes yeej zoo ib yam li qhov loj, zoo, thiab zoo li. Lawv tuaj yeem ua tau sib npaug lossis pear-puab hlwb. Gametes muaj flagella txav mus rau lawv qhov chaw. Thaum lawv fuse, ib tug zygote raug tsim, ua rau lub cev tshiab. Hom syngamy no yog pom los ntawm cov kab mob unicellular zoo li protozoans, cov nroj tsuag qis dua li algae thiab qee cov fungi.

Oogamy yog dab tsi?
Oogamy yog hom kev sib deev aniogamous. Nws tuaj yeem txhais tau tias yog qhov sib xyaw ntawm cov qe loj, tsis muaj zog nrog cov phev me me thiab txav mus los tsim cov zygote. Txiv neej thiab poj niam gametes muaj ntau qhov sib txawv ntawm qhov loj, zoo, zoo li thiab motility. Txiv neej gamete dais ib flagellum; yog li ntawd, nws yog heev mobile. Lub qe cell muaj ntau cov as-ham rau yav tom ntej siv thaum lub sij hawm kev loj hlob ntawm cov me nyuam.
Oogamy yog qhia los ntawm tag nrho cov nroj tsuag siab dua thiab tsiaj.

Qhov txawv ntawm Anisogamy Isogamy thiab Oogamy yog dab tsi?
Anisogamy vs Isogamy vs Oogamy |
|
| Definition | |
| Anisogamy | Anisogamy yog ib hom kev sib koom ua ke uas muaj qhov sib txawv ntawm cov txiv neej thiab poj niam gamete fuse ua ke los tsim cov zygote. |
| Isogamy | Isogamy yog ib hom kev sib koom ua ke uas morphologically zoo ib yam li ob lub gametes fused ua ke hauv kev sib deev. |
| Oogamy | Oogamy yog ib hom kev sib koom ua ke thiab kuj yog ib hom anisogamy uas tshwm sim ntawm cov qe qe loj thiab cov phev me me los tsim cov zygote. |
| Differentiation of Gametes | |
| Anisogamy | Poj niam thiab txiv neej gametes sib txawv. |
| Isogamy | Ob gametes tsis txawv li txiv neej thiab poj niam gametes. |
| Oogamy | txiv neej gamete thiab poj niam gamete sib txawv heev. |
| Size of the Gametes | |
| Anisogamy | Poj niam gamete loj dua txiv neej gamete. |
| Isogamy | txiv neej thiab poj niam gametes zoo ib yam loj. |
| Oogamy | Poj niam gamete loj dua txiv neej gamete. |
| Specialization of Gametes | |
| Anisogamy | Cells yog tshwj xeeb. Lawv txawv physiologically. |
| Isogamy | Cells tsis yog tshwj xeeb, tab sis lawv txawv ntawm lub cev. |
| Oogamy | Cells yog tshwj xeeb, thiab lawv yog physiologically txawv. |
| Flagella | |
| Anisogamy | Nyob hauv ib co kab mob, ob gametes yog motile thaum nyob rau hauv ib co hom, tsuas yog txiv neej gamete yog motile. |
| Isogamy | Ob gametes muaj flagella. |
| Oogamy | Txiv neej gamete yog motile thaum poj niam gamete tsis txav. |
| Anisogamy | Ntawm no ua rau cov xeeb ntxwv tsawg. |
| Isogamy | Qhov no tsim cov xeeb ntxwv ntau dua. |
| Oogamy | Qhov no ua rau cov menyuam yaus muaj zog dua. |
Summary – Anisogamy vs Isogamy vs Oogamy
Txiv neej thiab poj niam gametes tau sib xyaw ua ke los tsim cov zygote diploid thaum lub sijhawm kev sib deev uas yog hu ua syngamy. Cov txheej txheem no sib txawv ntawm cov kab mob, raws li qhov xwm ntawm gametes thiab hom fusion. Yog li ntawd, muaj peb hom syngamy hu ua isogamy, anisogamy, thiab oogamy. Isogamy tshwm sim ntawm ob qho tib si motile gametes uas tsis txawv li txiv neej thiab poj niam gametes. Anisogamy tshwm sim ntawm ob tug txiv neej thiab poj niam sib txawv gametes uas yog motile los yog immotile. Oogamy yog ib daim ntawv ntawm anisogamy uas tshwm sim ntawm immotile loj poj niam gamete thiab me me motile txiv neej gamete. Qhov no yog qhov txawv ntawm anisogamy isogamy thiab oogamy.
