The student will investigate and understand life
functions of archaebacteria, monerans(eubacteria), protists, fungi, plants, and
animalsincluding humans.
Key concepts include:• how their structures and functions vary between
and within the kingdoms;• comparison of their metabolic activities;• analyses of their responses to the environment;• maintenance of homeostasis;• human health issues, human anatomy, body
systems, and life functions; and• how viruses compare with organisms.

• Nonvascular Plants (Mosses, Liverworts & Hornworts)
•Nonvascular plants are the simplest of all land dwelling plants.
•They lack an internal means for water transportation.
•They do not produce seeds or flowers.
•They generally only reach a height of 1 to 2 centimeters, because they lack the woody tissue necessary for support.

Viruses• Viruses can

![Page 81: 6 Kingdoms of Life. Classification Key Words and Definitions in Cornell Notes ( with at least one example) 1. Unicellular – 2. Multicellular- 3. Eukaryote](https://reader036.vdocuments.net/reader036/viewer/2022062322/5697c0081a28abf838cc6876/html5/thumbnails/81.jpg)
Viruses• The viral reproductive process
includes the following steps:1. A virus must insert its genetic
material into the host cell.2. The viral genetic material takes
control of the host cell and uses it to produce viruses.
3. The newly formed viruses are released from the host cell.

Virus Treatment– Viruses cannot be treated with
antibiotics.
– There are some anti-viral drugs available.
– You generally have to wait for the virus to run its course and let your immune system fight it off.
