A screen for a window. It keeps bugs and other bad things out and lets air in.
A plastic ziploc bag. It allows certain things to permeate the plastic, and other things not to.
Uhhh, how about an egg or egg shell
The shell is porous to allow oxygen to get to the developing embryo, somewhat like a cell wall allows certain things to enter the cell

you can compare a cell membrane to a strainer because it controls what drains out or stays in
Both animal and plant cells have cytoplasm.
cell membrane
Many textbooks will compare a cell membrane to the fluid mosaic model, which means that the parts of the membrane (phospholipids, cholesterol, proteins etc.) are not stuck in one place; they move around and can pass by one another while still keeping the integrity of the membrane. That is mainly for the structure, but structure always lends to function.
where is the cell control membrane and the cell membrane
you can compare a cell membrane to a strainer because it controls what drains out or stays in
I would compare cilia to tires of a car, since cilia helps the cell move.
I had a project like this, I did a cell is like a city and I made the following organelles compared to everyday use from cities: Chloroplasts-Solar Panels Nucleus- Mayor Cell Wall- City Border Cell Membrane- City Gate Nuclear Membrane- Security Guard Cytoplasm- Streets Mitochondria- Powerplant Chromatin/DNA-Blueprints
I suppose you could compare the mantle to the cell wall or cell membrane.
vesicles
It is a soft object
Yours skin,
Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the membrane.
Vacuoles
something to represent a cell membrane would be a sponge because it lets things pass in and out of it
A cell membrane is similar to the object you use as a balloon. It forms the wall around the cell and allows some things to come in and some to go out. It is a boundary.
