Which is the sites of protein synthesis in a plant cell?
Ribosomes are attached to the endoplasmic reticulum and serve as sites for protein synthesis. Proteins synthesized on these ribosomes will be exported from the cell, moved into other organelles of the endomembrane system, or incorporated into membranes.
What are the 4 major organelles involved in protein synthesis?
The organelles involved in the process of protein synthesis include the nucleus, ribosomes, endoplasmic reticulum (ER) and the golgi apparatus (GA).
What is the site of protein synthesis in plant and animal cells?
Ribosomes
Protein is assembled inside cells by an organelle called a ribosome. Ribosomes are found in every major cell type and are the site of protein synthesis.
What is the source of protein synthesis in a cell?
The ribosome is a cytoplasmic structure in cells of prokaryotes and eukaryotes that are known for serving as a site of protein synthesis.
What are the organelles found in plant cells?
The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.
What are the parts of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
Where are things synthesized in the cell?
Cells synthesize proteins by making use of the amino acid pool present in the cell cytoplasm. Protein synthesis happens in broadly two steps called transcription and translation. It occurs on the ribosomes which are the sites for protein synthesis. Ribosomes are made up of ribosomal RNA.
What are the 4 structures found in all cells?
All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes.
Are there ribosomes in plant cells?

Which cell organelle has a role in synthesis of protein?
Ribosomes. Ribosomes are the protein factories of the cell.
Which of the major parts of the plant cell is responsible for photosynthesis?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
How are proteins synthesized in a cell?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What is the site of protein synthesis in a cell?
Protein is assembled inside cells by an organelle called a ribosome. Ribosomes are found in every major cell type and are the site of protein synthesis. Below is an illustration of your basic body cell. Inside, you’ll notice small circular structures–those are ribosomes, where protein is being synthesized.
What are the steps involved in protein synthesis in plants?
The following points highlight the eighteen steps involved in the protein synthesis in plants. (i) DNA in the nucleus or nucleoid in prokaryotes directs the synthesis of m-RNA and provides it with necessary genetic information in the form of codons for the formation of specific proteins.
Is protein synthesis in plants similar to that of bacteria?
As is obvious, the preceding account of protein synthesis in plants pertains mainly to those of bacteria (prokaryotes). It is similar in eukaryotes also but with many differences chief of which are: 1.
What are the three types of RNA involved in protein synthesis?
For protein synthesis three types of RNAs are involved to carry genetic information’s from nucleus to the site for protein synthesis. These are messenger RNA (m-RNA), transfer RNA (t-RNA) and ribosomal RNA (r-RNA).
