Hint: Cell is basic unit of life. The term cell was introduced by Robert Hooke in London. The study about cell structure, chemical composition, and function is called cell biology.

Complete Answer:
Basically two types of cells are present: Prokaryotic and Eukaryotic.
This classification is based on these features:
1) Organization of membrane
2) Variety of cytoplasmic organelles
3) Complexity of nuclear material

- Prokaryotic cell: These are a single membrane system and cell wall made up of peptidoglycans. Cell wall disperses the replicated substance to daughter cells.
- Eukaryotic cell: These are double membrane systems and cell walls do not contain peptidoglycans and the cell wall has no function in distributing the products.
- Cell organelle: In prokaryotic cell, cytoplasm do not have organelle except ribosomes while on the other hand Eukaryotic cell, Cytoplasm contain endoplasmic reticulum, mitochondria, golgi bodies, centrosome, microtubules, microbodies, lysosomes , and also ribosomes.

So, the correct answer is Ribosomes.

Additional information:
- Prokaryotic cell ribosomes are 70s units which are present in the free form or join with the cell membrane.
- Transcription and Translation only take place in the cytoplasm.
- This prokaryotic cell is present in the bacteria, cyanobacteria, mycoplasmas, rickettsias, and chlamydias.

Note: The main function of ribosome is the protein synthesis. The DNA formation in the prokaryotic cell occurs throughout life and DNA is circular which is present in the cytoplasm.
