What makes an egg cell specialised




















Egg cell. The cytoplasm contains nutrients for the growth of the early embryo. The haploid nucleus contains the genetic material for fertilisation. The cell membrane changes after fertilisation by a single sperm so that no more sperm can enter. Eggs are one of the biggest cells in the body and only a few are made. Ciliated epithelial cell.

Another specialisation of the sperm cell is the acrosome, which contains enzymes which dissolve the cell membrane of the egg and allows the sperm to fuse with the egg cell. The egg cell is specialised in a way that once this occurs the egg cell membrane reacts and prevents other sperm from entering.

Compare and contrast three ways in which sperm cells and egg cells are specialised for their functions Both sperm cells and egg cells contain a haploid nucleus, this means that they contain half the number of chromosomes of a normal diploid cell. Answered by Aoife C.
