Knowledge of cellular structure and function has increased dramatically with the advent of modern molecular and computational technologies. Helping students to understand cellular dynamics is a major challenge to educators. To address this challenge, we have developed the Kabala Engine, an open source engine based on OpenSG (http://www.opensg.org) and VRJuggler (http://www.vrjuggler.org). This engine is designed to enable biologists, and indeed any domain expert — chemists, artists, psychologists — to create virtual interactive worlds for teaching or research. As a proof-of-concept, we have used this engine to create Meta!Blast, a virtual plant cell containing a prototype chloroplast in which students can enter, activate the light reactions, including electron excitation, and create molecular oxygen and ATP.

And Function

The extent to which the properties of water in cells are like those of water in dilute aqueous solutions is a question of broad significance to cell biology. A detailed answer is not available at present, although evidence is accumulating that the properties of at least a large fraction of intracellular water are altered by interactions with cell ultrastructure, notably the cytomatrix. That and related evidence also suggests that the properties, composition, and activities of the "aqueous cytoplasm" of intact cells bear little resemblance to those of the "cytosol" obtained by cell fractionation. This paper will consider some of the evidence for these possibilities and some of their potential consequences with regard to cellular structure and function.

Systemic View

This study aimed to investigate Norwegian eighth-grade students’ preconceptions of cells, the development of their understanding of cellular structure and function during cell biology instruction, and their understanding of the cell as a system. We conducted pre- and posttests including drawings, images and statements with 28 students. Our findings indicate that most students had a simplified view of cells prior to instruction but developed significant knowledge about cellular structures and different types of cells during instruction. However, several misconceptions arose, and some students seemed to alter their correct preconceptions. This suggests that teachers need to address misconceptions during instruction and support integration of students’ previous and new knowledge. Additionally, we suggest that focusing on numerous structures and cells from different organisms confuses students and complicates the process of achieving a systemic view of the cell.

Keratin Intermediate Filaments

In 1991, a set of transgenic mouse studies took the fields of cell biology and dermatology by storm in providing the first credible evidence that keratin intermediate filaments play a unique and essential role in the structural and mechanical support in keratinocytes of the epidermis. Moreover, these studies intimated that mutations altering the primary structure and function of keratin filaments underlie genetic diseases typified by cellular fragility. This Retrospective on how these studies came to be is offered as a means to highlight the 25th anniversary of these discoveries.

‘Cellular structure and function’ covers the roles, structures, and functions of the main four types of macromolecules of the human body, namely proteins, lipids, carbohydrates, and nucleic acids. For these macromolecules, the roles and types of each class are discussed (for proteins this includes their roles as structural proteins and enzymes and their kinetics; for lipids, the roles and types of lipid found in the body are considered; for carbohydrates, their roles including structural and metabolic are discussed; and the structure of nucleic acids is described). Then follows a description of the organization of the cell, including the plasma membrane and its components, and the intracellular organelles. Cell growth, division, and apoptosis are covered, as are the formation of gametes, and finally the principles of how cellular functions can be modulated by pharmacological agents through receptors and signalling pathways are discussed.
