About This Chapter
Characteristics and Life Functions of Organisms - Chapter Summary
Come to understand humans as living organisms with life functions and many characteristics comparable to other life forms through this informative chapter. The online video lessons in this chapter also cover strategies and adaptations used by organisms to obtain requirements of life. Additional topics of study related to characteristics and life functions of organisms include the following:
- Taxonomy: classification and naming of living things
- Cladograms and phylogenetic trees: evolution classifications
- Evolution of prokaryotes: archaebacteria and eubacteria
- Evolution of protists: importance and evolutionary history
- Evolution of plants and fungi: characteristics and evolutionary history
- Evolution of animals: importance and evolutionary history
- Evolution of humans: characteristics and evolutionary history
- Factors that influence homeostasis within an organism
Each lesson in this chapter on characteristics and life functions of organisms has three components: a video presentation, a written transcript and a short, self-assessment quiz. The video lessons were developed by experienced professional educators to be brief yet thorough and engaging. The self-assessment quizzes allow you to see how well you've absorbed the information, which can indicate to you if there are areas where you need to put in some extra study time.
1. Taxonomy: Classification and Naming of Living Things
The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.
2. Cladograms and Phylogenetic Trees: Evolution Classifications
Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.
3. The Evolution of Prokaryotes: Archaebacteria and Eubacteria
The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.
4. The Evolution of Protists: Importance & Evolutionary History
Some organisms are very familiar. However, there are some that play vital roles in our lives that we don't even think about. We will look at a group of one of these unfamiliar kingdoms - protists.
5. The Evolution of Plants and Fungi: Characteristics & Evolutionary History
In early classification systems, plants and fungi were grouped together. While there are some similarities between these two kingdoms, there are some key differences that we will explore.
6. The Evolution of Animals: Importance & Evolutionary History
The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.
7. The Evolution of Humans: Characteristics & Evolutionary History
Just like other organisms, humans have changed over time. We will look at the evolution of humans as well as connections with our primate relatives, including Old World and New World primates.
