An analysis and an explanation of mitochondria a tiny organelles found in eukaryotic cells

Mitochondria and chloroplasts are the powerhouses of the cell. Mitochondria appear in both plant and animal cells as elongated cylindrical bodies, roughly one micrometre in length and closely packed in regions actively using metabolic energy.

Organelle An organelle is a tiny structure inside a cell that performs a particular function. Organelles are only found in eukaryotic cells those with a distinct nucleusand are not found in prokaryotic cells those without a distinct nucleus.

Both animal and plant contain many types of organelles or "little organs". Just as any organ has a specialized, particular function to perform as part of a larger system, so these "little organs" within a cell have certain tasks they perform.

Each organelle has a job to do that is crucial to maintaining the life of the cell and in most eukaryotic cells, organelles can be grouped into three categories according to their general function.

Both plant and animal cells have a nucleus. Organelles also function in transport, synthesis making thingsstorage, and recycling.

In plant and animal cells, the organelles responsible for these activities are called the endoplasmic reticulum, ribosomes, Golgi bodies, and lysosomes.

Plant cells also have organelles called vacuoles.

The endoplasmic reticulum is a complex network of folded membranes that form tubes and transport, or move, materials to all parts of the cell. They are something like a pipeline. Ribosomes play an important role in the synthesis, or making of, proteins. Golgi bodies look like a stack of flattened pancakes.

They put the finishing touches on proteins, and then sort the proteins and pack them for transport. Lysosomes are bags of enzymes that help a cell digest the food it takes in. Only plant cells have a large sac called a vacuole that they use for storage.

Other organelles function to produce energy.

Molecular Cell Biology. 4th edition.

Called mitochondria and chloroplasts, these organelles are responsible for changing energy from one form to another. Although chloroplasts also produce energy for cell, they are a little different than mitochondria for two reasons.

First, chloroplasts are not found in animal cells, they are only found in plant cells. Second, unlike animals that must take food into their bodies, plants can make their own food from which they obtain their energy. Plants create this food using small, green organelles called chloroplasts that capture the energy in sunlight.

Chloroplasts use this trapped radiant energy of the Sun and turn it into chemical energy for use or storage. When the plant is ready to use the energy, the mitochondria take over and release the stored energy.A Matter of Scale - interactive showing the sizes of things, from very tiny to huge - from NSF Organelles of Eukaryotic Cells Below is a list of organelles that are commonly found in eukaryotic cells.

Most eukaryotic cells contain many mitochondria, which occupy up to 25 percent of the volume of the cytoplasm. These complex organelles, the main sites of ATP production during aerobic metabolism, are among the largest organelles, generally exceeded in size only by the nucleus, .

Introduction to eukaryotic cells. By definition, eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal skybox2008.com addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria.

Kinetoplasts are a variation of the mitochondria found in some eukaryotic pathogens. In these organisms, each cell has a single, long, branched mitochondrion in which kinetoplast DNA, organized as multiple circular pieces of DNA, is found concentrated at one pole of the cell.
