| | GO:0060009 | | Sertoli cell development | | The process whose specific outcome is the progression of a Sertoli cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a Sertoli cell fate. |
| | GO:0009566 | | fertilization | | The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy). |
| | GO:0016337 | | single organismal cell-cell adhesion | | The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism. |
| | GO:0007286 | | spermatid development | | The process whose specific outcome is the progression of a spermatid over time, from its formation to the mature structure. |

| | GO:0005794 | | Golgi apparatus | | A compound membranous cytoplasmic organelle of eukaryotic cells, consisting of flattened, ribosome-free vesicles arranged in a more or less regular stack. The Golgi apparatus differs from the endoplasmic reticulum in often having slightly thicker membranes, appearing in sections as a characteristic shallow semicircle so that the convex side (cis or entry face) abuts the endoplasmic reticulum, secretory vesicles emerging from the concave side (trans or exit face). In vertebrate cells there is usually one such organelle, while in invertebrates and plants, where they are known usually as dictyosomes, there may be several scattered in the cytoplasm. The Golgi apparatus processes proteins produced on the ribosomes of the rough endoplasmic reticulum; such processing includes modification of the core oligosaccharides of glycoproteins, and the sorting and packaging of proteins for transport to a variety of cellular locations. Three different regions of the Golgi are now recognized both in terms of structure and function: cis, in the vicinity of the cis face, trans, in the vicinity of the trans face, and medial, lying between the cis and trans regions. |
| | GO:0000139 | | Golgi membrane | | The lipid bilayer surrounding any of the compartments of the Golgi apparatus. |
| | GO:0001669 | | acrosomal vesicle | | A structure in the head of a spermatozoon that contains acid hydrolases, and is concerned with the breakdown of the outer membrane of the ovum during fertilization. It lies just beneath the plasma membrane and is derived from the lysosome. |
| | GO:0031410 | | cytoplasmic vesicle | | A vesicle found in the cytoplasm of a cell. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0012506 | | vesicle membrane | | The lipid bilayer surrounding any membrane-bounded vesicle in the cell. |
