This module is designed to introduce you to the events that occur in the cell cycle and the process of mitosis that divides the duplicated genetic material creating two identical daughter cells. At the end you can test your understanding...

This excellent interactive website about cellular respiration provides an overview then goes into the details that can be so difficult to understand. The practice, review, and quiz pages should help solidify understanding.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. Students view online animations of cell membrane dynamics (links provided). Then they...

College-level course highlighting the biology of cells of higher organisms. Course topics include cellular membranes and organelles; cell growth and oncogenic transformation; transport, receptors, and cell signaling; the cytoskeleton,...

Use this information to help you understand the differences between major parts of the cell cycle. A good place to start a study of cell division.

An illustrated tutorial highlighting the process of cell division called mitosis.

In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson,...

A site about cell division and the cell cycle in the science of biology including mitosis, meiosis, and binary fission.

Tutorial on DNA basics that goes along with an online quiz over the material. Use the naviagation buttons at the bottom of the page to go to the quiz over the material.

Poses and answers the question, "What is (and is not) mitosis?" An overview with images of the phases of mitosis, plus a mitosis animation.

[Free Registration/Login may be required to access all resource tools.] The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes). Our...

[Free Registration/Login may be required to access all resource tools.] Describes the Krebs cycle.

In this activity you will be able to classify and count the cells from the tip of an onion root into the appropriate phases of the cell cycle. You can use your count to predict the time a dividing cell spends in each phase.

A collection of video lectures discussing applications of human biology taught at Massachusetts Institute of Technology. Lectures vary in length and cover topics like the cell cycle, stem cells, and cancer.

Learn about the process of cellular respiration in this tutorial.

Students compare and contrast passive and active transport by playing a game to model this phenomenon. Movement through cell membranes is also modeled, as well as the structure and movement typical of the fluid mosaic model of the cell...

This page contains diagrams and formulas for the Krebs cycle. The page has seven different catagories. The page is written by Clarke Earley, Ph.D., a chemistry professor at Kent State University.

Learners examine the major biological concepts related to the development and impact of cancer. The resource consists of a web version of the supplement, state standards, and downloadable materials.

This site will allow students to grasp the complex concept of meiosis by modeling the process with clay.

[Free Registration/Login may be required to access all resource tools.] How do you make a cell with half the DNA? Meiosis. This activity outlines the phases of meiosis, provides an overview of sexual reproduction, and describe how...

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are...

Every animal starts out as a single, fertilized cell. What happens then? Launch an interactive that showcases four similar-looking embryos. Can you guess what each one of them actually is? Watch them develop.

Informative text is clearly written and supported by good illustrations and charts as well. A quiz is also provided at the bottom of the site.

Students read an article about how the HIV virus replicates itself in a host cell, and the parts of an HIV particle. Includes labeled drawings of an HIV particle and of its replication cycle. The lesson materials and a set of PowerPoint...
