Select the part whose main job is to help a plant cell make proteins.<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The part of the plant cell whose main job is to help make proteins is the ribosome<\/strong>.<\/p>\n\n\n\n Ribosomes are essential cellular structures found in all living cells, including plant cells, and are responsible for protein synthesis. They are often referred to as the “factories” of the cell because they translate the genetic information carried by messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.<\/p>\n\n\n\n In plant cells, ribosomes can be found in two locations: free in the cytoplasm and bound to the endoplasmic reticulum (ER), specifically the rough ER. The rough ER is studded with ribosomes, giving it a “rough” appearance. This association is critical because proteins synthesized on the rough ER are often destined for secretion or for use in cellular membranes.<\/p>\n\n\n\n The process of protein synthesis begins when a gene on the plant’s DNA is transcribed into mRNA in the nucleus. The mRNA then exits the nucleus and enters the cytoplasm, where it attaches to a ribosome. The ribosome reads the sequence of codons on the mRNA, each corresponding to a specific amino acid. Transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome, where they are linked together in the order specified by the mRNA, forming a polypeptide chain.<\/p>\n\n\n\n Once the polypeptide is synthesized, it may undergo further modifications in the rough ER and Golgi apparatus before becoming a fully functional protein. These proteins can serve various roles in the plant, including enzymes, structural components, and signaling molecules.<\/p>\n\n\n\n In summary, ribosomes play a crucial role in protein synthesis in plant cells, enabling the cell to produce the proteins necessary for growth, development, and response to environmental stimuli.<\/p>\n","protected":false},"excerpt":{"rendered":" Select the part whose main job is to help a plant cell make proteins.
