The Golgi Apparatus is an important organelle found in eukaryotic cells that helps with the creation, sorting and modification of molecules used throughout the cell.

Organelles allow for many of the different required functions of the eukaryotic cell to be performed in specialized subcellular structures.

Cells that are small and primitive, or large and more complex, are organized to promote their sustenance and survival. Even the simplest of cells are very complex.

The Endoplasmic Reticulum (ER) organelle is made up of two types, smooth and rough endoplasmic reticulum, which carry out different functions in the cell.

The eukaryotic cells of plants and animals possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles.

Both plant and animal cells are eukaryotic, with many similarities, but there are also key differences between the cells of plants and animals. Here is a summary.

Round and round they spin, those centrifuges, creating high g-forces as they work and - under the right conditions - molecules and organelles separate and layer within.

Plants are eukaryotes, composed of cells that have a nucleus, and membrane-bound organelles. But plants have a few different features than animal cells. Here's a summary.

The cell's endomembrane system consists of the rough and smooth ER, Golgi apparatus, vesicles and plasma membrane, all working together to transport cellular materials.

This lesson will make the parts of a cell very memorable by using a child's natural creativity to make comparisons.

Mitochondria provide all of the energy for a cell, making them some of the most important organelles in the cell.

The cell nucleus may be the most important organelle in the cell for students to understand. It contains the DNA which controls nearly all cell activity inside the cell.

What specifically are the main differences between prokaryotic and eukaryotic cells? Here is a side by side comparison to simplify mastering the basics of cell structure.

Ribosomes, which can be free floating in the cell or attached to endoplasmic reticulum, carry out the steps of protein synthesis in the cell.

Researchers use the genetic material from 3 people to circumvent mutations in the mother's mitochondrial DNA (mt DNA).

Cell membranes once seemed to be simple cell structures. Today, membranes are recognized as complex, highly-organized structures that still require intensive research.

Stephen King's novel "Cell" brings us back to the good old days of gore and horror in King's frighteningly twisted mind. A brief review of Stephen King's novel "Cell".

Some basic physics, chemistry and biology can offer a quick foundation for laymen wishing to better understand how DNA, genes and chromosomes work.

With recent news about three parent zygotes created to replace defective maternal mitochondrial DNA, you might be wondering "What is a mitochondrion?"

Biologists have identified seven characteristics that all living things share.

Archaea are prokaryotes that differ from bacteria and eukaryotes enough to be assigned to their own taxonomic domain. Here is a brief introduction to Archaeans.

Mutations in the mitochondrial DNA can reduce the function of the mitochondrion, the power house of the cell, resulting in metabolic syndromes and disorders of metabolism

Scientific classification sorts all life forms on Earth into five kingdoms: monera, protista, fungi, plantae, and animalia. Together they form the tree of life.

Many science students are looking for short-cuts to make learning cell biology effortless. There are none, but there are strategies to help compare the two cell types.

This classroom activity can be used to familiarize students with basic cell structure and encourage them to think about how the membrane system of eukaryotes works.

Protein tubes and fibers help to assemble and move organelles to cellular locations. These protein aggregates make up the cytoskeleton.

Problems with chromosome number or structure can have serious implications for the individual affected.

The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

The phospholipid bilayer of the cell membrane protects the cell, provides structural support and controls the flow of molecules into and out of the cell.

All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

First discovered in the 1800s, chromosomes are cell bodies that provide efficient storage for DNA.

Bacteria and viruses are both tiny infectious agents with the ability to cause disease. So it is not surprising that these microbes are sometimes mistaken as the same.

The stability of cell shape and structure are maintained by cytoskeletal proteins that interact with and transport required functional molecules.
