A shoe box is one, because it protects the shoes from any damage of the outside world.
One example is the cell wall common to most bacterial organisms. Another is the cell wall surrounding fungi. A third is the plant cell wall.
a city! mitochondria would be the power plant, ribosomes would be factories, nucleus would be like the city hall or town center, the wall/membrane would be like the border line, so on
fence, city gate, etc
Fabric, cloth, tissue
Shoe box, doors, phones
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.
water house
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.
A Real-Life Object Example(Like for a model / project) Could be something fuzzy.
Any cell that contains a nucleus is considered a eukaryote. On the other hand, prokaryotes are simple cells that lack a nucleus. Both types of cells have a organelles.
Maybe but the real answer is the time in your life
The ozone or an eggshell
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
a honeycomb cell...(BEE's NEST)
Real life is a real life example!
This is kinda hard
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.
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.
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.
