Surprise, they’re not all the same. But many researchers think cells’ crucial protein factories, organelles known as ribosomes, are interchangeable, each one able to make any of the body’s proteins. …
Q. What two things make up ribosomes?
Ribosomes are composed of two subunits, the large and the small subunit, both of which consist of ribosomal RNA (rRNA) molecules and a variable number of ribosomal proteins. Several factor proteins catalyze different steps of protein synthesis by binding transiently to the ribosome.

Q. Are ribosomes in plant cell?
Ribosomes are organelles located inside the animal, human cell, and plant cells. They are situated in the cytosol, some bound and free-floating to the membrane of the coarse endoplasmic reticulum.
Q. Is DNA in plant cells?
Summary. Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts.
Q. What cell organelle makes ribosomes?
Cell Organelles and Functions
| A | B |
|---|---|
| Nucleolus | A small, dense region in the nucleus that makes ribosomes |
| Nucleus | Controls most cell processes and contain the hereditary information of DNA |
| Ribosomes | Small particles made of RNA; assemble proteins |
Q. Is a nucleus an organelle?
A nucleus is a membrane-bound organelle that contains the cell’s chromosomes.
Q. Do plant cells have plasmids?
It is called chromosomal DNA and is not contained within a nucleus. Bacteria also have small, closed-circles of DNA called plasmids present in their cytoplasm….Bacterial cells.
| Feature | Eukaryotic cell (plant and animal cell) | Prokaryotic cell (bacterial cell) |
|---|---|---|
| Size | Most are 5 μm – 100 μm | Most are 0.2 μm – 2.0 μm |
