In eukaryotic cells, which are found in complex organisms including humans, little membrane-bound organelles carry out various functions. It's been suggested that these organelles, which all have ...
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.
Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. These components vary depending on whether the cell is prokaryotic or eukaryotic, and whether it belongs to a plant, animal, fungus, or protist.
All cells can be sorted into one of two groups: eukaryotes and prokaryotes. A eukaryote has a nucleus and membrane-bound organelles, while a prokaryote does not. Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells.
The 3D Cell Viewer is a tool for viewing thousands of 3D images of cellular structures and organelles.
For the first time, researchers have directly visualized how newly formed cellular organelles leave the endoplasmic reticulum (ER) and transition onto microtubule tracks inside living cells. This new ...
