Cultured examples of these groups have shown that many live in tight symbiotic relationships, often exchanging nutrients and chemical signals. Sukunaarchaeum may push this dependency even further.

Examples of endoparasites include flukes, tapeworms, fungi, bacteria, and protozoa. Ectoparasites include ticks and lice, plants, protozoa, bacteria, and fungi.

This allows scientists to identify commonality in biological discoveries and extrapolate findings from one species to another. 2 For example, early insect, plant, bacterial, and viral models of ...

Animals Examples of specialised cells in animals include: Ovum - egg cell: contains half of an organism’s genetic information - DNA - which will join with the sperm during fertilisation.
