What is a cell membrane similar to?
Cell Membranes When you think about a membrane, imagine it is like a big plastic bag with some tiny holes.
That bag holds all of the cell pieces and fluids inside the cell and keeps any nasty things outside the cell.
The holes are there to let some things move in and out of the cell..
What does the cell membrane keep out?
Cell membranes serve as barriers and gatekeepers. … Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
How does the cell membrane protect against viruses?
Summary: When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.
How is the cell membrane similar to the cell wall?
1 Answer. Cell wall in plants is made of cellulose fibers and other cementing materials, while cell membrane is made of phospholipids and proteins. Cell walls have the function of support while cell membranes control what gets inside and out side the cell.
What has the same function as a cell membrane?
The cell wall protects the cell and runs along the entire perimeter like the cell membrane. Something that has the same function is a wall of a building.
What are the 6 functions of the cell membrane?
Terms in this set (6)Molecule Transport. Helps MOve food, water, or something across the membrane.Act as enzymes. Controls metabolic processes.Cell to cell communication and recognition. so that cells can work together in tissues. … Signal Receptors. … intercellular junctions. … Attatchment to the cytoskeleton and ECM.
What’s the weakest muscle in your body?

What is the smallest organ in your body?
pineal glandWhat’s the smallest organ in the human body? You’ll find the pineal gland near the center of the brain, in a groove between the hemispheres.
Which organ has a function that is similar to that of the cell membrane?
The skin surrounds the entire body just as the cell membrane surrounds the entire cell. Both the skin and the cell membrane are semi-permeable, meaning that they only allow specific substances to enter or exit the body.
What does the cell membrane let in and out?
The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane.
How is the plastic bag like a cell membrane?
A plastic sandwich bag is a good model of a cell membrane. Like a cell membrane, it has millions of invisible tiny holes that allow small molecules to pass through. Larger molecules cannot pass through. The sandwich bag and the cell membrane are selectively permeable.
What’s the strongest muscle in a human body?
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
What is the largest organ in your body?
The skin is the body’s largest organ.
What are the 3 functions of a cell membrane?
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the …
