two membranes, for example the mitochondrion and the chloroplast.
A cell containing organelles surrounded by membranes that is found in most living plants and animals is a eukaryotic cell.

Eukaryotic organelles are typically surrounded by membranes that are lipid bilayers similar to the plasma membrane. These membranes serve to compartmentalize the organelles, allowing distinct environments to facilitate specific biochemical processes. For example, the endoplasmic reticulum and Golgi apparatus have membranes that are involved in protein synthesis and modification, while mitochondria have a double membrane that plays a crucial role in energy production. This compartmentalization is essential for the proper functioning of the cell.
They do but the organelles are not bound in membranes.
Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.
Organelles are surrounded by membranes to provide a barrier that controls what substances can enter and exit the organelles. This helps to maintain the organelle's internal environment, protect its contents, and facilitate specific functions within the cell. Additionally, the membranes of organelles contain specialized proteins that are essential for the organelle's structure and function.

No, a prokaryote is a cell that does not have a nucleus or other organelles surrounded by membranes. Bacteria are prokaryotes.
Eukaryotic organelles are typically surrounded by membranes that are lipid bilayers similar to the plasma membrane.

Organisms that are composed of unstructured cells surrounded by membranes are prokaryotic cells. A prokaryotic cell is a single-celled organism like an amoeba.
There isn't a specific number of membranes that a eukaryote has, mainly because it is unknown how many organelles are in a cell and how many cells are in an organism. A eukaryotic cell is surrounded by one plasma membrane, but most organelles within the membrane are also covered with membranes, sometimes two in case of mitochondria or chloroplast.
Prokaryotes
the membranes of eukaryotes form organelles. E.g. endoplasmic reticulum is made of membranes.
