Question

In angiosperms, are sperm and eggs produced by mitosis or meiosis? Which cells are spores? Which structures are gametophytes?

Accepted Answer

Welcome back. Here's our next question. It says in angiosperms micro spores are produced by biotic division inside the micro story in jam after pollination. The micro spore germinates to form the male gamete a fight which is. And our choices are deployed hap Lloyd mutant or hybrid. Well let's recall that in plants and flowering plants. We have the alternation of generations and we have the structure of the micro spore in gym which is deployed and cells and other cells in the micro spare and undergo mitosis. As we see in our problem to produce micro spores. The micro spores then germinate to form the male camino. Fight the micro spores germinate and perform the male unified by mitosis. So recalling from our content videos what goes on in mitosis and mitosis. We know that the deployed micro spirit medium after undergoing mitosis will give rise to half Lloyd micro spores. The micro sports don't undergo mitosis. Well after mitosis the daughter cells will be genetically identical to the parent cells. So in that case the male domino fights are also happy Floyd. So when we look at our answer choices, we see that choice B. Is hap Lloyd. When we look at our other choices we can rule them out, they're not deployed. They've undergone the parent cells undergoing mitosis. They're not mutant. This is a normal process. Nothing has nothing has gone wrong in producing those male camino fights and they're not hybrid. They're not a hybrid of two different things. This is just the regular steps of development to produce a happily to fight. So choice D. Is not our answer. So again, the micro sport will germinate to form the milk of the Freedom Fight, which is Choice be hap Lloyd. See you in the next video.
