Which is not a double membrane structure?

Which is not a double membrane structure?

Answer. Nucleoli are not typical organelles for the reason that they have no lipid membrane, making it with of the few non-membrane bound organelles in the cell. The nucleolus is located within the nucleus of eukaryote cells and is in charge of producing ribosomal RNA and the arrangement of ribosomes.

Which of the following is double membrane structure?

The mitochondrion is double membrane bound organelle wherein the inner membrane is present as infolding and forms cristae. The chloroplast is double membrane-bound organelle in which the inner membrane surrounds the alkaline stroma and thylakoid system. So, the correct answer is option D.

In which organelle is the double membrane absent?

Lysosomes

Is not enclosed by a double membrane?

Answer. Explanation: Single Membrane bound Organelles: Lysosomes, Peroxisomes, Vacuoles Organelles lacking any membrane: Ribosomes, Centrioles, Nucleolus Nucleus and Ribosomes 1 Genetic Control of the Cell Nucleus: is the most distinct structure inside cell visible with light microscope.

Is nucleolus single or double membrane?

Nucleoli are the sites of translation of rRNA into protein-rich ribosomal subunits that exit the nucleus through pores in the double membrane nuclear envelope.

Which of the following is not membrane bound?

Ribosomes are the protein factory of a cell. These are non-membranous organelle which attaches on endoplasmic reticulum by transcolon.

Which of the following is membrane bound?

Endoplasmic reticulum, nuclei, lysosomes, Golgi apparatus and mitochondria are membrane bound cell organelles whereas ribosomes are naked ribonucleoprotein protoplasmic particles.

Is nucleolus membrane bound?

The nucleolus is a non-membrane bound nuclear compartment found in eukaryotic cells which is the site of ribosome biogenesis. The interphase nucleolus is organized around the tandemly repeated genes for preribosomal RNA (rRNA).

How many of the following structures in a cell are not bound by any membrane?

Nucleolus, ribosomes and centrioles are not bounded by a membrane.

Which organelle does not have membranes?

Non-membrane bound organelles are more solid structures that are not fluid-filled, so they have no need for a membrane. Examples of non-membrane bound organelles are ribosomes, the cell wall, and the cytoskeleton.

Which cell has no membrane bound?

Prokaryotic cells
