Organelles

A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell.

The vault or vault cytoplasmic ribonucleoprotein is a eukaryotic organelle whose function is not fully understood.

The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment.

Chloroplasts /ˈklɔːrəˌplæsts, -plɑːsts/ are organelles, specialized subunits, in plant and algal cells.

A flagellum (/fləˈdʒɛləm/; plural: flagella) is a lash-like appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells.

The Golgi apparatus (/ˈɡoʊldʒiː/), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.

The kinetochore (/kᵻˈnɛtəkɔər/, /-ˈniːtəkɔər/) is a protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart.

Proteasomes are protein complexes inside all eukaryotes and archaea, and in some bacteria.

In platelets, the term "alpha granules" is used to describe granules containing several growth factors.

In cell biology a centriole is a cylindrical cell structure composed mainly of a protein called tubulin that is found in most eukaryotic cells.

A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells.

A lysosome is a membrane-bound organelle found in most animal cells.

A spliceosome is a large and complex molecular machine found primarily within the splicing speckles of the cell nucleus of eukaryotic cells.

A vacuole (/ˈvækjuːoʊl/) is a membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells.

Phycobilisomes are light harvesting antennae of photosystem II in cyanobacteria, red algae and glaucophytes.

Peroxisomal disorders represent a class of medical conditions caused by defects in peroxisome functions.

Ciliogenesis is defined as the building of the cell's antenna (primary cilia) or extracellular fluid mediation mechanism (motile cilium).

Dense granules (also known as dense bodies or delta granules) are specialized secretory organelles.

An ocelloid is a subcellular structure found in the family Warnowiaceae (warnowiids), which are a members of a group of unicellular organisms known as dinoflagellates.
