[Micronucleus] 1. The smaller nucleus in ciliate protozoans, such as the Paramecium. In fission it divides by mitosis, and in conjugation it furnishes the pairing of gamete nuclei
[macronucleus] 2. The larger type of nucleus in ciliates. They are polyploid and undergo direct division without mitosis. They control the non-reproductive cell functions and everyday tasks, such as metabolism.
[Kinetoplast] 3. A network of circular DNA (called kDNA) inside a large mitochondrion that contains many copies of the mitochondrial genome. Commonly found in protozoa
[Kinetostome] 4. An organelle formed from a centriole, and a short cylindrical array of microtubules. It is found at the base of a eukaryotic cilium or flagellum and serves as a nucleation site for the growth of the axoneme microtubules.

[soma] 4. Parts of an organism other than its reproductive cells
[spermatheca] 5. receptacle where sperm will be stored after mating
[viviparous] 6. bringing forth live young that have developed inside the body of the parent.
