Question

name the cell organelle which is not bound by a membrane in eukaryotes​

Answer 1

Answer:

Cell organelles with no membrane In eukaryotic cell, ribosomes occur freely in the cytoplasmic matrix and are attached to the outer cytoplasmic surface of the rough matrix of mitochondria and stroma of plastids called as mitoribosomes and plastidoribosomes, respectively. ... Prokaryotic cell lack lysosomes.

Answer 2

The cell organelle which is not bound by a membrane in eukaryotes​ is centriole.

• Cell organelles are dense bodies present in the cell and generally specialized to perform a particular function.
• Some cell organelles are not bounded by a membrane, for example, ribosomes, cilia, flagella, centriole, etc
• Ribosomes are found both in prokaryotes and eukaryotes, however, prokaryotes have 70S type while eukaryotes have 80S type.
• Centrioles form the cytoskeleton of skell and are mainly composed of tubulin filament.
