Fertilization is the process by which two terminally differentiated cells, the sperm and the egg, merge to form a totipotent cell, the zygote. This review addresses one of the culminating steps in getting sperm and egg together: the cell-cell interactions that allow the two gametes to fuse and...
The cytol- ogy of gametes and the timeline of fertilization process have been well described3–5, while most of the very early cellular events just after membrane fusion and molecular mechanisms involved remains relatively unknown6–9. This is largely due to double fertilization occurs internally, ...

(pollen grain cell) encases the two sperm cells, the female gametophyte (embryo sac) is multicellular in a more conventional sense, and consists of seven cells – three small antipodal cells, the large central cell (which contains two polar nuclei that fuse prior to fertilisation), the egg ...
The development of seeds in flowering plants starts with the fertilization of the maternal gametes by two paternal sperm cells. This leads to the formation of two products, embryo and endosperm, which are surrounded by a tissue of maternal sporophytic origin, called the seed coat. The development...
In the unique double fertilization process in flowering plants, both the egg cell and the neighbouring central cell fuse with a sperm cell each. Here we succeeded in imaging cytosolic Ca2 þ in these two cells, and in the two synergid cells that accompany the gametes during semi-in vivo ...
Several molecules are able to induce the sperm acrosome reaction; however, this process should be produced coordinately in time and in the space to allow the success of fertilization between gametes. The goal of this study was to analyze the metabolites secreted by cumulus-oocyte-complex (COC) ...
a. Sister chromatids do not separate correctly in Meiosis 2. b. Extra sets of chromosomes segregate in Meiosis, leading to aneuploid gametes. c. These cells are too big to fuse correctly during fertilization. d. Extra set Explain the process of ...
On the cell surface, host cell fusion molecules, like ADAMs, could cause the HPIV2 infected host cell membrane to fuse with the neighboring non-infected cells to form syncytia. This strategy might enable fusion of dozens of non-infected cells to a giant multi-nuclear cell which means that ...
