WebApr 11, 2024 · cut. In plants, the great majority of studies indicating haploid selection have been carried out using male haploid tissues in angiosperms. Hence, evidence in these systems is confounded with the effects of sexual selection and intra-specific competition. Evidence from other plant groups is scarce and results show no support for the masking … WebMay 4, 2024 · Both the micropyle and megasporangium are diploid tissue of the sporophyte and are connected to the ovary wall by a region of tissue called the funiculus. The funiculus connects to a region of the ovary called the placenta, where nutritive support is provided the ovary wall and supplied to the developing ovule.
