Chapter 6: A Tour of the Cell
Concept 6.1 Biologists use microscopes and the tools of biochemistry to study cells 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference. Magnification is the ratio of an object’s image size to its real size. Resolution is a measure of the clarity of the image; it is the minimum distance two points can be separated and still be distinguished…show more content…

The nuclear lamina, a netlike array of protein filaments, connects the layers of the nuclear envelope. 12. What is the nuclear lamina? Nuclear matrix? The nuclear lamina is the netlike array of protein filaments that maintains the shape of the nucleus by mechanically supporting the nuclear envelope. The nuclear matrix is a framework of protein fibers extending throughout the nuclear interior. The nuclear matrix and nuclear lamina may help organize the genetic material so it functions efficiently.

Found within the nucleus are the chromosomes. They are made of chromatin. What are the two components of chromatin? When do the thin chromatin fibers condense to become distinct chromosomes? Chromatin is composed of proteins and DNA. Chromatin fibers condense to become distinct chromosomes as a cell prepares to divide.


When are the nucleoli visible? What are assembled here? Nucleoli are visible in a nondividing nucleus and in cells active in protein synthesis. Within the nucleoli, proteins imported from the cytoplasm are assembled with rRNA into large and small subunits of ribosomes.


What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.


Ribosomes in any type of organism are all the same, but we distinguish between two

IB Biology is challenging, college-level biology, so sometimes you will need a little more study help than your class notes provide. In this article, I've compiled the best FREE online IB Biology study guides (including IB Biology Notes and IB Biology Revision) into one useable resource and provided you with some IB Biology practice questions. I will order this IB Biology Study Guide using the IB Biology Syllabus.


How to Use This IB Biology Study Guide

If there is a single topic you are interested in learning more about, use the Command + F function on your computer to search the article for that term. For example, if you want to learn more about Cell Theory, use Command + F to bring up the search function. Type in “Cell Theory” and it will bring up all of the study materials for Cell Theory.

If you are looking for general quiz material for the whole IB Biology Exam, you can skip to the end of the article to the Overall Reviews section for great overall study resources.

First, I will delve into resources by IB Biology Topic. I will separate the resources into:

  • Quick Reference: These guides primarily come from the site IB Guides. They're short summaries of the information that often include definitions and diagrams.
  • Longer Notes: These longer notes come from the site BioNinja. They're a more in-depth look at the material, and you can focus on the specific topic you're interested in by clicking on the topics listed on the left side of the page.
  • Overview: The IBWorld site has all the notes for each topic on one webpage. It's especially a good resource for people who want to be able to just read through a lot of notes without clicking through different pages to get to different topics.
  • Slideshow: These are powerpoint-type presentations on the material.
  • Video: Demonstration videos on how to solve problems related to the material. They come from two different sources since neither one covers all the IB Biology topics.


How Should You Use This Guide Throughout the Year?

You should use this guide throughout the year as a refresher before tests and quizzes or for additional support if you did not entirely understand a specific lesson in your IB Biology class. If you still need more assistance, check out our article on the Best IB Biology Books. You should be studying throughout the year and not waiting to cram before the IB Biology exam.   

You should also be integrating real practice questions with each subject. You can find past IB Biology HL and IB Biology SL papers for sale online from the Follett IB store. Also, if you are struggling to understand the material, you should be studying the corresponding chapter in a review book as you learn that chapter in class. 




Common Mistakes Students Make When Studying for IB Biology 

Many students have a hard time with IB Biology. There is a lot of material to cover and you need to be learning it throughout the year(s) in order to master the IB Biology exam. Some common mistakes students make when studying are:

  • Ignoring subjects you don't understand in class: If you do not understand it in class, you need to seek more help whether through IB Biology study guides, IB Biology books, or through tutoring. 
  • Only worrying about studying right before the IB Biology exam: There is way too much material to cover to learn it all in a few days or weeks (there is a reason it is spread over one to two years). Learn the material as you cover it in class. Use this study guide for help understanding the concepts you cover in class.

Command Terms

  • Slideshow: Excellent interactive slideshow that gives you tips and tricks.
  • Knowing the command terms is the most crucial part of the IB Biology Exam. If you do not understand the difference in command terms (such as Draw, Annotate, Outline, Analyze, etc.), you will not be able to answer the questions correctly.
