Ib txoj kev xav uas piav qhia txog keeb kwm ntawm sporophyte hauv cov nroj tsuag hauv av yog lub npe hu ua interpolation theory lossis antithetic theory. Nyob rau hauv no txoj kev xav, lub hauv paus chiv keeb ntawm sporophyte pib thaum lub zygote nyob rau hauv lub neej voj voog ntawm ib tug multicellular, haploid ntsuab alga faib los ntawm mitosis es tsis txhob ntawm meiosis

sporophyte pib tsim qhov twg?

Lub embryonic sporophyte tsim hauv lub archegonium, thiab cov sporophyte paub tab nyob nrog rau gametophyte. Lub sporophyte tsis yog photosynthetic. Yog li ob lub embryo thiab cov laus sporophyte tau noj los ntawm gametophyte.

Dab tsi tuaj thawj sporophyte lossis gametophyte?

The gametophyte tiam yog suav tias yog laus dua li tiam sporophyte, txij li thaum, nyob rau hauv evolution, kev loj hlob ntawm kev sib deev muaj tseeb preceded lub alternation ntawm tiam. Cov lus no tau txais kev txhawb nqa los ntawm kev sib raug zoo ntawm gametophyte muaj nuj nqi thiab xav tau dej rau phev motility.

pom sporophyte nyob qhov twg?

Ib tug sporophyte yog ib tug multicellular diploid tiam pom nyob rau hauv cov nroj tsuag thiab algae uas tau hloov pauv ntawm ntau tiam neeg. Nws tsim cov spores haploid uas tsim los ua gametophyte.

qhov tseem ceeb sporophyte hloov zuj zus los ntawm qhov twg?

Phylogenetic cov ntaub ntawv tau pom tias sporophyte-dominant, tracheophyte lub neej- voj voog hloov zuj zus los ntawm a gametophyte-dominant life-cycle.
