1. Acrosome
A membrane-bound section at the tip of the head of a sperm which contains lytic enzyme s (hyaluronidase in mammalian sperm) which break down the outer coat of the egg and allow the sperm to inject its haploid DNA .

2. Acrosome
Anterior membrane-bound compartment covering the sperm head that contains lytic enzyme s, which help the sperm digest through the tough outer surface of the egg . The compartment is secreted by the Golgi apparatus of the spermatid (young sperm cell).

3. Acrosome reaction
A chemical change that enables a sperm to penetrate an egg .

4. Agameon
An organism that reproduces asexually only, without producing gamete s ( sperm or egg s).

5. Albumin
A heat-coagulatable, water-soluble globular protein found in egg white, blood plasma and many other plant and animal tissues. Albumin from cow blood is often used as an enzyme stabilizer.

6. Amniote egg
An egg with compartmentalized sacs (a liquid-filled sac in which the embryo develops, a food sac, and a waste sac) that allowed vertebrates to reproduce on land.

7. Amphibians
Class of terrestrial vertebrates which lay their eggs (and also mate) in water but live on land as adults following a juvenile stage where they live in water and breathe through gills. Amphibians were the first group of land vertebrates; today they are mostly restricted to moist habitats.

8. Androgenetic merogony
The development of an egg fragment that has been fertilized by sperm but has no nuclei from the egg.

9. Antisperm antibodies
Antibodies that can attack sperm and inhibit their movement or block fertilization of the egg .

10. Arachidonate (arachidonic acid)
An essential unsaturate d fatty acid that humans use to synthesize regulatory molecules such as prostaglandin s and thromboxanes . It is found in fatty animal tissue such as egg yolk and liver.
