Question

The function of the ampulla of spermatheca is
(a)To store sperms
(b)To nourish sperms
(c)To secrete sticky material during copulation
(d)None of the above

Answer 1

Hint: The spermatheca is well known as receptaculum seminis. This is an organ of the female reproductive system in insects, examples are ants, bees, certain molluscs, oligochaeta worms, and some other invertebrates and vertebrates.

Complete answer:
The motive of spermatheca is to collect and store sperm from the male or, within the instance of hermaphrodites, the male parts of the body. The sperms stored within the spermatheca are nourished by the ampulla. In the female reproductive tract, the spermatheca is an ectodermal organ liable for collecting, maintaining, and delivering sperm to fuse with eggs. The number and morphology of spermatheca vary consistently with species. Inside the spermathecal lumen, substances within the semen and secretions from the spermathecal gland nurture the sperm. Therefore, spermatheca gives a proper environment that makes sure the long-term viability of sperm. Maintaining sperm feasible for long periods inside the spermatheca is important for insect reproductive accomplishment.

Additional Information: Some species of animals have multiple spermatheca. For instance, some species of earthworms possess 4 pairs of the spermatheca, each pair is present within the 6th, 7th, 8th, and 9th segments. The spermatheca collects and stores the spermatozoa of another earthworm throughout copulation. They are coated with epithelium and are variant in shape where few are thin, highly coiled tubes, while others are indefinite out pocketing from the most reproductive system. This is one of the many differences in sexual reproduction.
An apiculturist studied the spermatheca of a dead bee queen to seek out where it had collected sperm from a male. In various species of stingless bees, basically Melipona bicolor, the queen lays her eggs throughout the fitting and oviposition procedure and therefore the spermatheca fertilizes the egg because it goes along the oviduct. The haplodiploid system of sex determination makes it possible for the queen to settle on the sex of the egg.
So, the correct answer is 'To nourish sperms'.

Note: Spermatheca can sometimes be the site of fertilization when the oocytes are sufficiently developed. In Pheretima, the diverticulum stores sperms. The spermatheca opens externally by small ducts. Each spermatheca is flask-shaped. In earthworm four pairs, situated inter-segmentally between 5-6, 6-7, 7-8, and 8-9th segment. They may also be referred to as seminal receptacles as they store sperms from another earthworm throughout copulation.
