Types of Organelles

CYTOPLASM
CYTOPLASM

The organelles and cytosol, taken together, compose the cell’s cytoplasm. The nucleus is a cell’s central organelle, which contains the cell’s DNA . Figure 1. Prototypical Human Cell. While this image is not indicative of any one particular human cell, it is a prototypical example of a cell containing the primary organelles and internal structures.

Cytoskeleton
Cytoskeleton

They have a network of filaments known as the cytoskeleton (literally, “cell skeleton”), which not only supports the plasma membrane and gives the cell an overall shape, but also aids in the correct positioning of organelles, provides tracks for the transport of vesicles, and (in many cell types) allows the cell to move.

GOLGI BODY / APPARATUS
GOLGI BODY / APPARATUS

Golgi apparatus, also called Golgi complex or Golgi body, membrane-bound organelle of eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened, stacked pouches called cisternae.

LYSOSOMES
LYSOSOMES

Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

MITOCHONDRIA
MITOCHONDRIA

Organelles such as the mitochondria, the rough endoplasmic reticulum and the golgi serve respectively to generate energy, synthesize proteins and package proteins for transport to different parts of the cell and beyond.

Nucleolus
Nucleolus

The nucleolus (/ nj uː ˈ k l iː ə l ə s, - k l i ˈ oʊ l ə s /, plural nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis.

Nucleus
Nucleus

Cell nucleus. In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-enclosed organelle found in eukaryotic cells. Eukaryotes usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others have many.

PLASMA MEMBRANE/ CELL MEMBRANE
PLASMA MEMBRANE/ CELL MEMBRANE

The cell membrane is a type of plasma membrane that encloses the entire contents of a cell, including the cytoplasm and all the organelles. The cell membrane is not always the outermost layer of the cell since plant cells also have a cell wall that further encloses the cell membrane.

Ribosome (Little Dots)
Ribosome (Little Dots)

When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER".

RIBOSOMES
RIBOSOMES

All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA (rRNA) and 40 percent protein. However, though they are generally described as organelles, it is important to note that ribosomes are not bound by a membrane and are much smaller than other organelles.

Smooth Endoplasmic Reticulum
Smooth Endoplasmic Reticulum

In cell: The smooth endoplasmic reticulum The functions of the SER, a meshwork of fine tubular membrane vesicles, vary considerably from cell to cell. One important role is the synthesis of phospholipids and cholesterol, which are major components of the plasma and internal membranes.

Vesicle
Vesicle

Quick Answer. A vesicle is a small membrane-bound sack that stores and transports substances throughout the cell. They can form naturally within the cell to aid in cellular secretion such as exocytosis, endocytosis or phagocytosis or they can be artificially prepared by chemists and biologists.
