The Biology Project: Cell Biology
Tutorials and interactive quizzes covering cells, mitosis, meiosis, the cell cycle, prokaryotes, eukaryotes, & viruses. Part of The Biology Project.
Construction of the Cell Membrane
"The student will study the structure of the cell membrane by constructing it using the correct molecules." Learning object relevant to health sciences students studying nutrition, biochemistry and pharmacology.
Connecting Concepts: Plant Biology/Water Relations 2: Water Flow Through Whole Plants
Students follow movement of water through a plant from the soil to the atmosphere. They calculate water potential at each of 5 locations in the soil-plant-atmosphere continuum. Students will: 1) predict the value and direction of the solute potential and pressure potiential in different parts of a plant, given information about physical conditions; and 2) calculate the water potential for soil, root cell, xylem, mesophyll cell, leaf air space, and atmosphere.
Virtual Cell Animations
Virtual Cell contains animations developed to introduce students to new concepts including; transcription, translation and the lac operon. By walking through the still images and movies, viewers can easily choose between either studying a specific step from one of the processes or taking a more immersive look at the process in it's entirety.
Cell-ebration
This site has been created to show students how cells work. It reviews the functions of the cell organelles. This web site focuses on the structure and function of the cell membrane. Students will learn how the organelles interact with each other to keep the cell alive. This web site adds to the knowledge of most middle school students about organelles and expands to how the cell works as a whole. Scientists who study this area are known as cell physiologists. Physiology is the study of the func
Plants in Motion
TIme lapse movies of plant growth from germination to flowering, including tropic responses, nastic movement and circadian rhythms.
Blood Cell Basics
Students will make a proportional model of blood out of red gelatin, a plastic bag, and rice. They will learn about the different components that make up blood and will investigate what happens when the arteries and veins experience buildup from cholesterol. They will then work in pairs to brainstorm ways to clean our clogged arteries.
Orchestrating cell separation in plants: What are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants ‘shed’ parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the ‘shedding’ proces

2.1 Introduction In this section we are going to review the different needs that drive the creation of corporate governance frameworks. The contingent model of regulation applies to financial reporting: the idea that equilibrium in regulation exists, but is broken by some intrusive event, often a financial scandal. This leads to a search for a revision of the rules, and a new equilibrium is worked out. This is very much a pattern that drives change in corporate governance.

In this hands-on activity, students build their own two-cell battery. They also determine which electrolyte solution is best suited for making a battery.

This RLO describes the timing and main events for each of the phases of the menstrual cycle. It concentrates on the main events occurring in the ovary and uterine wall during these phases
• Nobel Laureates 2010 is a 56 minute documentary that explores the lives and careers of this year's Nobel Laureates who have been awarded the highest honour in their respective fields. From Japan to Peru, Spain, America and the Philippines, the film takes us all over the world, interviewing extraordinary people as diverse as the Peruvian Literature Laureate Mario Vargas Llosa and one of the youngest Physics Laureates, 36 year old Russian born Konstantin Novoselov. Filmed on location in their
Moral Foundations of Politics (PLSC 118)
Marxism is the second Enlightenment tradition upon which the course will focus. Contrary to popular belief, Marx did not hate capitalism but derived from economic analysis that it would self-destruct and lead to socialism. It is also a myth that Marx did not care about freedom; he was only egalitarian in the sense that he wanted everyone to have freedom. Ergo, Professor Shapiro asserts that Marx's dialectical materialism is as committed to the two princi
A chapter which describes the mechanisms of signal transduction in a eukaryotic cell, including the activation of G-proteins and kinase cascades (49 figures). The unit is intended as ~10hrs study at level 2/3. It also provides background reading for the experimental investigation 'Investigating intracellular signalling pathways' (http://open.jorum.ac.uk/xmlui/handle/123456789/1581).
A virtual laboratory that includes immuno-gold labelling and transmission electron micrography (immuno-EM). It allows the student to study intracellular-traffic pathways of two cell-surface receptor molecules, following stimulation of the cells with their specific ligand, for different time periods. The programme first introduces the theory underlying the techniques and includes a video of EM work in a real laboratory. The student is then taken through a series of questions which requires them t
A virtual laboratory which allows users to analyse intracellular signalling pathways. The programme allows the student to stimulate cells for different periods of time and analyse phosphorylation/activation of kinases in the signalling pathways, using SDS-PAGE and immunoblotting. Use of different cell types (dominant-negative mutants) and pull-down assays allows them to derive the hierarchy in the signalling pathways. The programme first introduces the theory behind the techniques. It then takes
A protein analysis laboratory using SDS-PAGE, western-blotting and endoprotease digestion. The programme includes a section on the theory of the techniques, a video demonstration in a real laboratory, and a series of questions which guide the students through the structural analysis of model proteins (3 are included). Students go to the virtual laboratory and devise their own experiments in order to determine the molecular weight, subunit composition etc of the proteins. Results (gels and blots)
