organelles Cell components that carry out individual functions; e.g., the cell nucleus and the endoplasmic reticulum. Subcellular structures (usually membrane-bound and unique to eukaryotes) that perform some function, e.g.
organelles - membrane bound structures found inside the cell.
prophase - stage of mitosis in which replicated chromosomes condense; nuclear membrane dissociates; centrioles migrate to the poles of the cell.
Organelles
Main article: Organelle
The human body contains many different organs, such as the heart, lung, and kidney, with each organ performing a different function.
Organelles are formed bodies within the cytoplasm that perform certain functions. Some organelles are surrounded by membranes, we call these membrane-bound organelles.
Organelles enclosed in membranes, containing digestive enzymes.

The organelles of this flagellated alga are clear, such as the red eyespot, the chloroplasts, and the flagella. Unrestricted, Euglena moves in a rotating motion using its flagella.
Some organelles have two membranes. A mitochondrion has an outer and inner membrane. The outer membrane contains the mitochondrion parts. The inner molecule holds digestive enzymes that break down food.
other organelles, such as mitochondria, that have ceased functioning properly and have been engulfed in autophagosomes

ciliary organelles Organelles of specialized function formed by the fusion of cilia.

The mitochondrial permeability transition (mPT) involves the opening of a non-specific pore in the inner membrane of mitochondria, converting them from organelles whose production of ATP sustains the cell, to instruments of death.
Eukaryotic cells contain many organelles. Until the invention of the electron microscope little was known about the cell organelles which are too small to be resolved in the light microscope.
Mitochondria are membrane-bound organelles, but they're membrane-bound with two different membranes. And that's quite unusual for an intercellular organelle.
It is the rough endoplasmic reticulum that is directly continuous with the nuclear envelope (as illustrated in Figure 1), which is also studded with ribosomes, and the two organelles are thought to have evolved simultaneously in ancient cells.

Chloroplasts and mitochondria are organelles within eukaryotic cells (cells of organisms other than bacteria, which do not have organelles). These organelles have their own genetic material.
This view, championed by Lynn Margulis, speculates that these ATP-producing organelles were once free-living prokaryotes that were engulfed by a proto-eukaryote - an idea now strongly supported.
An organism lacking a nuclear membrane and certain organelles such as mitochondria. Refers to both Bacteria and Archae. This term was used synonymously with bacteria before the differences between Bacteria and Archae were understood.
They are tiny packets, or bags of organelles or tools needed for the cell to survive. A cell can eat, move around, and reproduce. these cells took the chemicals of life, found in the soup, and put them together inside protective sacks.
Prokaryotic cells do not have a true nucleus. They have few organelles, and have no membrane-bound organelles. In cyanobacteria, the cell membrane folds inward in a number of places allowing for the attachment of enzymes.
The prokaryotic cells do not have membranous organelles, although their membranes have invaginations that extend into the cytosol. Those invaginations determine certain functions, like the secretion of substances and the synthesis of DNA and RNA.

Eukaryote: Organism whose cells have (1) chromosomes with nucleosomal structure and are separated from the cytoplasm by a two-membrane nuclear envelope, and (2) compartmentalization of functions in distinct cytoplasmic organelles.
eukaryotes with a nucleus and rod shaped chromosome but no mitochondria or plastid, thus believed to be the intermediate stage between prokaryotes and eukaryotes. They are also used as evidence for the evolution of nucleus before the organelles.
