Def. "[t]he scientific study of plants, ... [t]ypically those disciplines that involve the whole plant"[3] is called botany.

Usage notes:

"The scientific definition of what organisms should be considered plants changed dramatically during the 20th century. Bacteria, algae, and fungi are no longer considered plants by those who study them. Many textbooks do not reflect the most current thinking on classification."[4]

"This path has attracted 'archaeaologists' with great tenacity and drive, impressive creativity and dynamic thinking, and a capacity to expand a mental comfort zone to broker remarkable observations, often in view of reluctant acceptance."[5]

Def. the scientific study of the archaea is called archaeaology.

"The B recognition element (BRE) is a DNA sequence found in the promoter region of most genes in eukaryotes and Archaea.[6][7]"[8]

In the archaean from the Dead Sea imaged at the right, "We have completely fragmented their DNA. I mean we have completely destroyed it by bombarding it with [radiation]. And they can reassemble their entire chromosome and put it back into working order within several hours."[9]
