Eukaryotic Cell Structure and Function PDF

By definition, eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal cells. In addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others. In previous sections, we began to consider the Design Challenge of making cells larger than a small bacterium — more precisely, growing cells to sizes at which, in the eyes of natural selection, relying on diffusion of substances for transport through a highly viscous cytosol comes with inherent functional trade-offs that offset most selective benefits of getting larger. In the lectures and readings on bacterial cell structure, we discovered some morphological features of large bacteria that allow them to effectively overcome diffusion-limited size barriers e. As we transition our focus to eukaryotic cells, we want you to approach the study by constantly returning to the Design Challenge. We will cover a large number of subcellular structures that are unique to eukaryotes, and you will certainly be expected to know the names of these structures or organelles, to associate them with one or more "functions", and to identify them on a canonical cartoon representation of a eukaryotic cell.

Cell Structure and Their Functions. Some organisms, such as bacteria, may exist solely as single-celled creatures. Bailey, Regina. Your Citation. A structure within a eukaryotic cell that carries out specific activities inside the cell is called a n. Biconcave shape Do not contain organelles including nucleus Contain only hemoglobin.

2.3: Eukaryotic Cell: Structure and Function

A eukaryotic cell has a true membrane-bound nucleus and has other membranous organelles that allow for compartmentalization of functions. Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have:.

The cell from Latin cella , meaning "small room" [1] is the basic structural, functional, and biological unit of all known organisms.
