The process whose specific outcome is the progression of a spermatid over time, from its formation to the mature structure.

The resolution of the male germline syncytium or cyst into individual gametes by packaging each spermatid into its own plasma membrane.

Any process that stops, prevents or reduces the rate that oskar mRNAs are effectively translated into protein.

Establishment and maintenance of a specific axis of polarity of the oocyte microtubule network. The axis is set so that the minus and plus ends of the microtubules of the mid stage oocyte are positioned along the anterior cortex and at the posterior pole, respectively. An example of this is found in Drosophila melanogaster.

The process in which anatomical structures of the veins on an imaginal disc-derived wing are generated and organized.

The process in which the anatomical structures of the imaginal disc-derived wing margin are generated and organized. The wing margin is a strip of cells in the third instar disc at the boundary between the presumptive dorsal and ventral surfaces of the wing blade.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A macromolecular complex containing both protein and RNA molecules.
