genus
In scientific contexts, the word "genus" is used as a technical term in biology. When writing the name of a specific genus (like Panthera), it should always be capitalized and italicized. In general conversation, the word is much less common and is used formally to describe a 'category' or 'type' of thing. It sounds more academic than words like "kind" or "sort." The plural form of genus is usually "genera," though "genuses" is sometimes accepted in non-scientific writing.

Eleanor is using her characteristic all-caps typing style and questioning the academic rigor of a child's project. Karen uses the phrasal verb 'mess with (someone's) head', meaning to confuse or psychologically manipulate someone, reflecting her stressed and protective parenting style.
