Qualities of Living Organisms - Chapter Summary
In these lessons, you'll learn about the qualities of living organisms. Topics covered include asexual reproduction in animals, fertilization of flowering plants, and major types of cells. Digestive, circulatory, and respiratory systems will also be discussed. After completing the chapter, you should be able to do the following:
- Describe seven common characteristics of all living organisms
- Detail the three primary structures that all cells have
- Explore how cytoplasm is key to cellular health
- Identify tissue types in humans and tissue systems of plants
- Recognize some of the eleven organ systems that keep the human body functioning
- Explain the pros and cons of various types of reproduction
- Describe how generations of flowering plants are produced
Our subject matter experts provide plenty of examples while discussing the qualities of human organisms in these short and engaging video lessons. The video timelines let you navigate the videos and review topics in any order. You can use the Help feature to submit questions to instructors if you get stuck on a topic. A brief multiple-choice quiz is available for each lesson to assess your understanding of the concepts reviewed.
1. The Defining Characteristics of Living Organisms
A house is not a living thing, but the people, animals, and plants living inside it are. So how do we define 'life'? Learn about seven characteristics that all living organisms have in common, no matter how different they may look on the outside.
2. What are Cells? - Overview
All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.
3. What is Cytoplasm? - Definition & Functions
Did you know your cells are filled with a thick fluid? Cytoplasm is an important part of your cells and serves several functions that are key to cellular health and productivity.
4. What Are Tissues? - Types & Explanation
Learn about the different tissues that are found in humans and plants. This lesson summarizes the four tissue types in humans and the three tissue systems of plants.
5. What Are the Organ Systems of the Human Body?
In this lesson, you'll learn about the 11 organ systems, which are made of multiple organs that work together to keep the human body functioning. Using easy-to-understand descriptions and illustrations, we'll explore the circulatory, respiratory and digestive, systems, among other types, after which you'll have the chance to take a brief quiz and see how well you understood the material.
6. Asexual & Sexual Reproduction in Animals
No species of animal can live forever, so it needs to reproduce. In this lesson we'll talk about how animals reproduce, and some of the pros and cons of the different types of reproduction.
7. Flowering Plants: Reproduction & Fertilization
Some plants use flowers to reproduce. The flowers contain all the parts needed for the reproduction process. This lesson explains how all of these parts are used to create the next generation of flowering plants.
8. Asexual Reproduction in Plants: Advantages, Disadvantages & Types
Plants are successful because they have evolved to have a variety of ways to reproduce. In this lesson, we will examine asexual reproduction in plants to learn the types, as well as the pros and cons of this means of reproduction.
