Chloroplasts, mitochondria and the nucleus have double membranes.
DNA
Ribosome is a cell organelle not bounded by membrane. It is responsible for protein synthesis in the cell.
No, bacteria do not have membrane-enclosed organelles like eukaryotic cells do. Instead, the internal components of bacteria are not separated by membranes but may be organized by intracellular structures such as ribosomes, nucleoid regions, and plasmids.
Chloroplasts, mitochondria and the nucleus have double membranes.
Vacuoles
A sac bounded by a single membrane is called a lysosome. This organelle is present only in animal cells and contributes in intracellular digestion.
Ribosomes and Centrioles
The mitochondria and the chloroplast.
A dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material
No, peroxisomes do not have a double membrane. They are single-membraned organelles that contain enzymes involved in various metabolic reactions, such as detoxification of harmful substances and fatty acid metabolism.
They are called Prokaryotic.
Bacteria have no nucleus at all
