A shoe box is one, because it protects the shoes from any damage of the outside world.
The nuclear envelope is a double membrane structure that surrounds the nucleus of eukaryotic cells. One real-life example of the nuclear envelope is in human cells, where it helps to protect and segregate the genetic material within the nucleus from the rest of the cell. Another example is in plant cells, where the nuclear envelope plays a similar role in protecting and organizing the genetic material.
cell membrane!!! not ribosomes! -wrong plant cells have cell walls and animal cells have cell membrane, it might seem right but it is wrong. Nearly all cells have a mitochondrion.^ While the answer above is correct, the real answer is Cell Membrane. So all cells have cytoplasm, AND cell membranes.
A eukaryotic cell, meaning "real" or "true" nucleus.
Lysosomes are membrane-bound organelles found in animal cells that contain digestive enzymes to break down waste materials, cellular debris, and pathogens. They function as the recycling centers of the cell by breaking down macromolecules into smaller components that can be reused by the cell. Lysosomes play a crucial role in maintaining cellular homeostasis and are involved in processes such as autophagy and phagocytosis.
As a general rule, practically all the internal organelles of a cell are covered by a protective membrane, except for one type, which couldn't even be called a real organelle, and those are the Ribosomes. More a macromolecular assemble than a cell organelle, the reason because they aren't membrane-bound is because they can directly interact with the membrane in order to exchange proteins, so, having their own membrane would actually act as a barrier for them to do their job correctly.

Yes, protists have a cell membrane. The cell membrane in protists acts as a barrier that separates the cell's internal environment from the external environment, helping to regulate the flow of substances in and out of the cell.
People live in towns. People are multicellular organisms consisting of trillions of cells. Each cell has a cell membrane.
example: secretion of proteins like enzymes, peptide hormones and antibodies from cells. the cell membrane folds inward, trapping a small amount of matter from the extracellular fluid. :)
the answer is insulin

Real life is a real life example!
The cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The cytoplasm is about 80% water and is usually colorless.

Osmosis certainly does happen regularly in real life. Osmosis is the transportation of water from one side of a membrane to the other side of a membrane.
