About This Chapter
1. Grana in Biology: Definition & Function
Grana are a necessary part of the process of photosynthesis. In this article you will learn exactly what grana are: their structure, function, and prevalence, and will test your knowledge with a short quiz.
2. Radial Symmetry in Biology: Definition & Examples
One way that animals are broadly categorized is based on their body symmetry. Radial symmetry is one type, and here, we will explore what it is and what organisms exhibit it. Once you get to the end of the lesson, you can test your knowledge with a brief quiz.
3. Selective Permeability: Definition & Overview
This lesson will provide you with a definition of selective permeability. Also, an example and illustration will be provided to support your understanding of the process.
4. Spontaneous Generation: Definition, Theory & Examples
Did you know that people (scientists included) thought that mice came from wheat and old shirts? Learn about theory of spontaneous generation and the centuries-long debate over its validity.
5. Taxon: Definition & Examples
Categorization and organization are key to better understanding our world. In biology, we have a classification system known as taxonomy. In this lesson, we'll look at the idea of a taxon in biology.
