Ribosomes are complex molecular machines that are set up inside the living cells that produce proteins from amino acids during a process called protein conflation. The process of protein synthesis is the main function, which is performed by all living cells. Every living cell requires ribosomes to produce protein within it. They are set up free in the cytoplasm of the cell and also attached to the rough endoplasmic reticulum. Now that we know about the ribosomes located in living beings, have you wondered where are ribosomes in a plant cell located? Let’s read further to know about the ribosomes function in a plant cell.

1. What Cell makes Ribosomes?

The part of the cell which makes ribosomes is the nucleolus which is a darkly painted, spherical body located inside the nucleus. The nucleolus assembles the protein and combines it with the 4 rRNA strands and forms the ribosomes. These ribosomes are later exported to the cytoplasm where they further make proteins for the cell. Therefore, it concludes that the nucleolus is the portion of the cell which forms ribosomes and there can be more than one nucleolus in a cell.

2. Are there Ribosomes in a Plant Cell?

Yes, plant cells have ribosomes that follow the process of protein synthesis while being present in the cytoplasm. So, where are ribosomes in a plant cell found? Both prokaryotic and eukaryotic cells include ribosomes, which are mainly specialized cell organelles.

So, plant cells do have ribosomes since they’re eukaryotic likewise, ribosomes are essential natural factors that are responsible for protein conflation. Ribosomes are complicated natural structures that make proteins and are set up in all cells which are substantially present in the cytoplasm, still, some performing ribosomes can also be set up in eukaryotic cell capitals.

3. Where are Ribosomes in a Plant Cell?

Now you must be wondering, where are ribosomes in a plant cell found? Plant cells have free ribosomes moving free in the cell cytoplasm and also attached to the rough endoplasmic reticulum. Ribosomes admit information from the cell core and construct material from the cytoplasm. The two subunits are joined to each other by relations between the RNAs in one subunit and proteins in the other subunit. Ribosomes are located inside the cytosol set up in the plant cell and animal cells. (See Hydroponics: Plants That Grow In Water Only)

4. Do Plant Cells have Free Ribosomes?

Plant cells have free ribosomes which are organelles, also located in the cytoplasm inside the animal and human cells, and in the plant cells, they are either free or attached. They’re positioned in the cytosol, some set, and free-floating to the membrane of the coarse endoplasmic reticulum. Ribosomes are set up free in plant and animal cells which are made up of protein and ribosomal RNA. They attach amino acids to form a long protein chain. (See Are Sea Anemones Plants or Animals?)

5. Where are Free Ribosomes located?

A ribosome is a small round organelle that is known as the protein factory of the cell set up in the cytoplasm. Then, where are ribosomes in a plant cell if they are free ribosomes? Some of the ribosomes which are located in the cytoplasm, without being attached to any organelle are known as free ribosomes. The crucial difference between free and attached ribosomes is that free ribosomes aren’t attached and are freely located in the cytoplasm while attached ribosomes are attached to the endoplasmic reticulum. 

However, these ribosomes group together and form structures that are further known as polysomes. They’re free-floating in the cytoplasm and move all around the cell. (See How many Types of Cells are There in The Human Body?)

6. How many Ribosomes are in a Plant Cell?

Ribosomes are exceptionally abundant in cells. A single diligently replicating eukaryotic plant cell, for example, may contain as numerous as 10 million ribosomes. 

7. Is Ribosome found in Plant Cell Nucleus?

No, the process of translation occurs in the cytoplasm due to the presence of ribosomes. The nucleus does not contain any ribosomes in the plant cell. Must read what are the examples of living things?

8. Are Ribosomes found in Mitochondria?

Yes, ribosomes are found in mitochondria. Mitochondrial ribosomes perform protein synthesis inside mitochondria. The organelles are responsible for energy conversion and adenosine triphosphate products in eukaryotic cells. The mitochondria consist of special ribosomes for this purpose. (See What are the End Products of Photosynthesis?)

9. Do Plant Cells have Ribosomes and Mitochondria?

Yes, plant cells have ribosomes and mitochondria. The plant organelles in a plant cell are the component that contains their genetic material, DNA, and ribosomes which include mitochondria and plastids. So, where are ribosomes in a plant cell exist? In a eukaryotic cell, ribosomes are found in the cytoplasm, mitochondria, and plant chloroplasts. The centriole is the cell organelle that is absent in plant cells. (See What are the Three Parts of Cell Theory?

10. What is the Ribosomes Function in a Plant Cell?

Ribosome functions in a plant cell are:

  • They are the protein builders or the protein synthesizers of the cell. They’re like construction guys who connect one amino acid at a time and make long chains. 
  • They are special because they’re set up in both prokaryotes and eukaryotes cells and they are present in millions.
  • There are two types of ribosomes, free ribosomes, and attached ribosomes. The attached ribosomes are bound to the surface of the endoplasmic reticulum and are the place for protein synthesis. Synthesis of proteins also occurs in the free ribosomes where the cell organelles correspond to RNA and proteins. 
  • They are responsible for producing the proteins of the cell. 

11. Where is the Ribosome located in Animal Cells?

Apart from learning where are ribosomes in a plant cell found, let’s also read the details about the animal cells. Ribosomes are located in animal cells on the endoplasmic reticulum inside the cell organelles, they’re responsible for the generation of proteins. This process always takes place inside the cytoplasm of the cell where occasionally the protein generated is to be transported to other regions of the cell or outside the cell body. The ribosomes attached to the endoplasmic reticulum or cell organelle form a canal for the transport of molecules across the cell membrane and facilitate the process of synthesis.

Ribosomes perform two very important biological activities which are decoding the message and formation of peptide bonds. So it can be stated that ribosomes are very important for human survival and growth. Therefore, now you must be aware of where are ribosomes in a plant cell located and also about their main function of protein synthesis. (Also read How Many Cells Are in the Human Body?
