Which Organelle Structure Do Both Plants and Animal Cells Have in Common?
Both plant and animal cells share a common ancestry, which is why they have many similarities in their cellular structures. One of the most important organelles that both types of cells have in common is the ribosome.
Ribosomes are responsible for protein synthesis in cells. They are small, spherical organelles consisting of RNA and proteins. They float freely in the cytoplasm or are attached to the surface of the endoplasmic reticulum (ER). The ER is an organelle that helps to modify and transport proteins.
Ribosomes are composed of two subunits, a large subunit and a small subunit. The small subunit binds to the messenger RNA (mRNA) and reads the genetic code. The large subunit then binds to the tRNA (transfer RNA) and brings in amino acids to form the protein chain.
Because ribosomes play such a vital role in protein synthesis, they are found in all living cells. They are essential for the growth and functioning of both plants and animals.
