Autotrophs and Heterotrophs Living organisms require a continuous input of energy to maintain cellular and organismal functions such as growth, repair, movement, defense, and reproduction. Cells can only use chemical energy to fuel their functions, therefore they need to harvest energy from chemical bonds of biomolecules, such as sugars and lipids. Autotrophic organisms, namely plants, algae, and photosynthetic and chemosynthetic bacteria, convert inorganic materials into such biomolecules by...

Quantifying Respiration using Microrespirometers ExpandNOTE: In this experiment, you will measure the rate of cellular respiration for germinating seeds by measuring the rate of exchange for oxygen. As oxygen is consumed to provide energy, germinating seeds release carbon dioxide. This carbon dioxide is absorbed by potassium carbonate and thus the overall gaseous pressure of the respirometer will be reduced. HYPOTHESES: The experimental hypothesis is that germinating seeds will show a greater...

Whole Organ Tissue Culture

Whole organs can be cultured ex vivo using specialized bioreactors with the goal of repairing or replacing entire organs. This method uses a donor organ that is stripped of all cells, leaving behind the three-dimensional structure, which is then repopulated with new cells. This video demonstrates the whole organ culture of lungs and shows how a dynamic culture that mimics the mechanical stimulation in the body is needed to induce native tissue properties.

Here, we present the fabrication protocol of an organic charge-modulated field-effect transistor (OCMFET)-based device for in vitro cellular interfacing. The device, called a micro OCMFET array, is a flexible, low-cost, and reference-less device, which will enable the monitoring of the electrical and metabolic activities of electroactive cell cultures.
FAQs
Membrane-defined compartments separate cellular activities while still allowing them to coordinate. By keeping processes in distinct spaces, membranes help organize metabolism and signaling rather than letting all reactions occur together. This arrangement gives the cell controlled internal structure, and its importance becomes especially clear when comparing the coordinated compartments of eukaryotic cells with the organization of prokaryotic cells.
The cytoskeleton contributes more than mechanical support. It helps maintain cell shape, positions organelles, and supports movement of materials within the cell. These roles connect physical structure with function: organelle placement can support coordinated activity, while intracellular transport helps distribute materials where they are needed. Changes in cytoskeletal organization can therefore affect several cellular processes at once.
The comparison centers on how each cell type arranges molecules, membranes, organelles, and other structures to support life-sustaining functions. Examining these arrangements helps explain why prokaryotic and eukaryotic cells represent distinct forms of biological organization. It also provides a foundation for understanding how differences in internal structure influence metabolism, signaling, growth, and reproduction.
To analyze a specialized cell, researchers can relate its structural arrangement to the role it performs, then consider how cells with coordinated organization contribute to tissues and organs. This approach connects cellular features with larger biological function without treating cells as isolated units. It is useful in cell biology, development, and physiology, where organization helps explain specialization.
Disrupted cellular organization can impair function because membranes, cytoskeletal support, organelle positioning, and material transport no longer operate in their coordinated arrangement. Studying these disruptions helps connect changes inside cells with disease-related consequences. This perspective is relevant to biomedical research, where cellular organization provides a framework for examining how altered structure may affect signaling, metabolism, growth, or reproduction.
Examining organization across molecules, organelles, membranes, and cells helps explain how local interactions produce whole-cell behavior. Extending the analysis to tissues and organs reveals how cellular coordination supports larger biological systems. Consequently, this topic links molecular and cellular observations to broader questions in development and physiology, while also providing context for interpreting functional changes in biomedical research.
