Remember back to your high school biology class. Practise yous withal recollect the names and functions of all those niggling jail cell parts? A picayune foggy on the details, perhaps? Here'southward a quick refresher course of some of the major eukaryotic organelles to keep your science skills abrupt. It might come in handy for your next game of Trivial Pursuit!

Nucleus

Known every bit the jail cell's "command middle," the nucleus is a big organelle that stores the prison cell'south Deoxyribonucleic acid (deoxyribonucleic acid). The nucleus controls all of the cell'south activities, such as growth and metabolism, using the Dna'southward genetic information. Inside the nucleus is a smaller construction called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the Dna's orders to the remainder of the jail cell and serves as a template for protein synthesis.
Ribosomes

Ribosomes are the protein factories of the cell. Composed of ii subunits, they can be found floating freely in the jail cell's cytoplasm or embedded within the endoplasmic reticulum. Using the templates and instructions provided by ii different types of RNA, ribosomes synthesize a variety of proteins that are essential to the survival of the cell.
Endoplasmic reticulum

Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells.
Encyclopædia Britannica, Inc.

The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus. Some portions of the ER, known as the crude ER, are studded with ribosomes and are involved with protein manufacture. The rest of the organelle is referred to as the smooth ER and serves to produce vital lipids (fats).
Golgi appliance

Golgi appliance
The Golgi apparatus, or circuitous, plays an important role in the modification and transport of proteins inside the cell.
Encyclopædia Britannica, Inc.

If the proteins from the crude ER require further modification, they are transported to the Golgi apparatus (or Golgi circuitous). Like the ER, the Golgi apparatus is composed of folded membranes. Information technology searches the protein's amino acid sequences for specialized "codes" and modifies them accordingly. These processed proteins are then stored in the Golgi or packed in vesicles to be shipped elsewhere in the cell.
Chloroplasts

chloroplast construction
The internal (thylakoid) membrane vesicles are organized into stacks, which reside in a matrix known every bit the stroma. All the chlorophyll in the chloroplast is contained in the membranes of the thylakoid vesicles.
Encyclopædia Britannica, Inc.

In plants and some algae, organelles known equally chloroplasts serve as the site of photosynthesis. Chloroplasts contain a pigment known as chlorophyll, which captures the dominicus'due south energy to transform water and carbon dioxide into glucose for food. Chloroplasts allow autotrophic organisms to meet their energy needs without consuming other organisms.
Mitochondria

Mitochondrion cut longitudinally.
Encyclopædia Britannica, Inc.

The "powerhouses" of the prison cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate). ATP fuels cellular processes by breaking its loftier-energy chemic bonds. Mitochondria are most plentiful in cells that require significant amounts of energy to role, such as liver and muscle cells.
