Presence of Ribosomes in Plastics and Chloroplasts

Introduction
Ribosomes are small structures present in cells that play a crucial role in protein synthesis. They are found in both prokaryotic and eukaryotic cells. However, the presence of ribosomes in plastics and chloroplasts is a topic of debate.

Ribosomes in Plastics
Plastics are synthetic materials that are created by humans. They are not living organisms and do not have cells. Therefore, they do not have ribosomes. Ribosomes require genetic material to function, and plastics do not possess any genetic material.

Ribosomes in Chloroplasts
Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They are unique because they have their own DNA and can reproduce independently of the cell. Chloroplasts contain ribosomes that are similar to those found in prokaryotic cells. These ribosomes are responsible for synthesizing proteins needed for photosynthesis.

Conclusion
In conclusion, ribosomes are not present in plastics as they are not living organisms and do not possess genetic material. However, ribosomes are present in chloroplasts, which are organelles found in plant cells responsible for photosynthesis. Chloroplasts have their own DNA and can reproduce independently of the cell. The ribosomes found in chloroplasts are similar to those found in prokaryotic cells and are responsible for protein synthesis needed for photosynthesis.

Ribosomes present only in chloroplast bcoz only chloroplast plastid have circular DNA.... so to form proteins from it there is requirement of ribosomes
