Module 3: The First Four Kingdoms

September 16, 2014 PowerPoint  Honors Marine Biology Module 3

Kingdom Monera represents the least complex organisms in creation. The Monera Kingdom consists of unicellular lifeforms. Unicellular means that they only have one cell. Moneran cells are far simpler and more basic than the cells of other lifeforms. These cells have no nucleus, and are also missing many of the organelles, or parts, commonly found in other cells.

Monera are classified into two phyla, or groups, autotrophs and heterotrophs. Autotrophs are able to create their own food, similar to plants. Heterotrophs cannot create their own food, and so must rely on autotrophs as their food source.

Monera is a kingdom that contains unicellular organisms with a prokaryotic cell organization, (having no nuclear membrane), such as bacteria. Kingdom Monera have been divided into two domains, Archaea and Bacteria (with Eukarya as the third domain).  Most bacteria were classified under Monera however, cyanobacteria (also known as the blue-green algae) were initially classified under Plantae due to their ability to photosynthesize.

The Protista Kingdom consists of unicellular lifeforms (lifeforms with only one cell) who have a nucleus. The primary difference between protists and monera is that protists are more complex, having a nucleus.  Many protists appear to be both plant and animal. Like plants, they are green, and can create their own food. However, like animals, they have moving body parts and are able to move around their environments. You can see why scientists no longer classify living things into two kingdoms.

Your class quiz for next week is to know Figure 2.6 Classification Table page 51

The Nitrogen Cycle

In class we set up a fish tank to explain the Nitrogen cycle. (Experiment 3.A)
