which of the following cell organelle is without any membrane
i- lysosome. ii-chloroplast
iii- nucleus iv - ribosome
Answers
Answer:
iv - ribosomes
Explanation:
Ribosomes are unique structures that translate the DNA code via messenger RNA (mRNA) into actual proteins that cells use for processes. Ribosomes are different from other organelles because they have no membrane around them that separates them from other organelles, they consist of two subunits, and when they are producing certain proteins they can become membrane bound to the endoplasmic reticulum, but they can also be free floating while performing their function.
Other organelles in the cell, such as the mitochondria and lysosomes, are enclosed by lipid membranes that separate them from other structures in the cell. Ribosomes exist as free structures that float throughout the cytoplasm of the cell. They do not have membranes, which allows them to pick up translational RNA released from the nucleus and grab onto free amino acids in order to produce protein chains.
