Ribosome

Vedclass · Answer

(B) In prokaryotic cells like bacteria,the plasma membrane can extend into the cytoplasm to form specialized structures. $1$. Mesosomes are infoldings of the plasma membrane that help in respiration,$DNA$ replication,and secretion. $2$. Tubules and lamellae are also extensions of the plasma membrane found in some photosynthetic bacteria. $3$. Vacuoles (gas vacuoles) are found in some prokaryotes but are not derived from the plasma membrane. $4$. Ribosomes are non-membrane-bound organelles found in the cytoplasm and are not derived from the plasma membrane. Since the question asks for structures $NOT$ derived from the plasma membrane,both Ribosomes and Vacuoles fit this description. However,in the context of standard biology curriculum regarding membrane extensions,Ribosomes are the most distinct non-membranous structures. Given the options,Ribosomes $(B)$ is the standard answer.

Which of the following is $NOT$ a structure derived from the plasma membrane of a bacterium?
