Does Cytoplasm Contain All The Organelles? 5 Facts

by

Cytoplasm is a semi liquid jelly like substances which connects the cell membrane with the nuclear membrane. Let us know whether it contains all the organelles.

Cytoplasm contains all the cellular organelles. In eukaryotes other than nucleus, all the contents inside the cell membrane is referred to as cytoplasm. In prokaryotes, cytoplasm contains the genetic material as they lack nuclear membrane.

Prokaryotic cells are more compact and have a simpler cytoplasmic organisation than eukaryotic cells.

How does cytoplasm contain the organelles?

The cytoplasm of the cell is made up of cytosol and organelles. Let us know how cytoplasm contains the organelles.

Cytoplasm of eukaryotic cell contains the complete interior and exterior, including the nucleus. Essential proteins, salts, and water make up cytoplasm. All of the eukaryotic cell’s organelles, such as the nucleus, endoplasmic reticulum, and mitochondria, are housed in the cytoplasm.

All the organelles found inside the cell membrane remains suspended in the cytoplasm.

Why nucleus is not included in cytoplasm?

Nucleus is a membrane bound organelle found in the eukaryotic cell . Let us understand the reason why nucleus is not included in the cytoplasm.

Nucleus is not included in cytoplasm because the nuclear membrane separates the material in the nucleus from the material in the cytoplasm. Therefore, the nucleus is not thought of as a component of the cytoplasm.

The cytoplasm is thus limited to the region of the cell membrane that is between the nuclear membrane and cell membrane.

How many organelles are there in cytoplasm?

A cell’s cytoplasm contains “little organs” called cytoplasmic organelles. Let us see in details regarding the number of organelles in cytoplasm.

The cytoplasm contains thirteen small organelles, that remains suspended in it. Each organelles have a specific structure and function. The mitochondrion, ribosomes, endoplasmic reticulum, golgi apparatus, and lysosome are a few examples of cytoplasmic organelles.

What organelles are located in the cytoplasm?

The cytoplasm is made up of the cytosol and the organelles, which are the internal substructures of the cell. Let us know about cytoplasmic organelles.

Listed below are the organelles located in cytoplasm–

  1. Endoplasmic Reticulum
  2. Ribosomes
  3. Golgi Apparatus
  4. Lysosomes
  5. Mitochondria
  6. Cytoplasmic Vacuoles
  7. Sphaerosomes
  8. Centrosomes
  9. Microtubules and Microfilaments
  10. Basal Granules or Kinetosomes
  11. Cilia and Flagella
  12. Tonofibrils
  13. Plastids

Endoplasmic Reticulum

The endoplasmic reticulum, also known as the ER, is a large, dynamic structure that performs a variety of functions in the cell, including calcium storage, protein synthesis, and lipid metabolism.

Ribosomes

The place where protein synthesis takes place in cells is called a ribosome, an intercellular structure consisting of both RNA and protein.

Golgi Apparatus

The Golgi apparatus is present in most eukaryotic cells. Prior to the vesicles being transported to their destination, it encapsulates proteins inside membrane-bound vesicles inside the cell.

Lysosomes

The membrane-enclosed organelles known as lysosomes are equipped with a variety of enzymes that can degrade different kinds of biological polymers.

Mitochondria

The majority of the chemical energy needed to power a cell’s metabolic processes is generated by mitochondria, membrane-bound cell organelles.

Cytoplasmic Vacuoles

The cell organelle known as a vacuole is membrane-bound. Small vacuoles that help hold waste materials in place are commonly present in animal cells. Vacuoles aid in preserving the equilibrium of water in plant cells.

Sphaerosomes

Small cell organelles known as sphaerosomes or oleosomes, which are surrounded by a single membrane, are involved in the synthesis and storage of lipids.

Centrosomes.

A centrosome is a cellular component that aids in cell division. The centrosome replicates before to cell division, and when division starts, the two centrosomes migrate to the opposing ends of the cell.

Microtubules and Microfilaments

The greatest cytoskeletal element, microtubules, undergo continual remodelling. They are composed of tubulin and are arranged in a hollow tube to aid in intracellular transport, cell division, and cell polarity.

Basal Granules or Kinetosomes

A cellular organelle with a high degree of conservation is the basal granules, also referred to as the kinetosome. The nine-fold symmetry upon which the cilium is constructed is provided by these barrel-shaped microtubular structures.

Cilia and Flagella

Cilia and flagella are mostly used for locomotion. They are the mode of transportation for several microscopic unicellular and multicellular creatures.

Tonofibrils

Epithelial tissues have cytoplasmic protein structures called tonofibrils, which converge at desmosomes and hemidesmosomes.

Plastids

Plastids are essential subcellular organelles that evolved to carry out specific tasks in plant cells, such as photosynthesis and the creation and storage of metabolites.

Why does cytoplasm contain the organelles?

All the components found outside the nucleus and inside the cell walls make up the cytoplasm. Let us examine why organelles are present in cytoplasm.

The organelles are found in cytoplasm because the functions of the organelles depends on the cytoplasm. Cytoplasm allows the organelles to function by filling the cells. The organelles transport chemicals via cytoplasm.

Conclusion:

The cell is shaped by its cytoplasm. The organelles are able to stay in place because it fills the cells to capacity. Without cytoplasm, cells would lose their volume and materials would have a difficult time moving between organelles. Instead, walls of the matrix entirely enclose the area of the cell that is free of organelles and surround the cytosol.
