The right answer is D.
A gamete is a generally haploid reproductive cell specialized in fertilization, or gamy (that is to say, able to fuse with another gamete, complementary type if necessary), in eukaryotes.
The process that carries out the fusion of two gametes is called fertilization or gamy, it is the complementary event of meiosis. Fertilization produces a new single cell, called a zygote, whose chromosome number has doubled to 2n.
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.

Note that Facilitated diffusion , Active transport and Osmosis are three different ways of transporting substances across the cell surface membrane.
Facilitated diffusion is the movement of a substance from high to low concentration , similar to simple diffusion , but due to the complexity of the cell surface membrane , polar molecules and ions cannot just pass like that , so they pass through specific carrier and channel proteins in the cell surface membrane and so we call it facilitated diffusion.
For Active transport , it's the movement from low to high concentraion using energy from ATP
For Osmosis , it's totally different . You only name osmosis when its all about water . Its the net movement of water from high water potential to low water potential through partially permeable membrane .
If you're doing AS , you'll be familiar with Endosmosis and Exosmosis.
