Where can selectively permeable membranes be found in a plant cell?
Selectively permeable membranes can be found in several locations within a plant cell, most notably in the plasma membrane that surrounds the cell. This membrane regulates the movement of substances in and out of the cell, allowing essential nutrients to enter while keeping harmful substances out. Additionally, selectively permeable membranes are present in the tonoplast, which encloses the central vacuole, and in the membranes of organelles such as chloroplasts and mitochondria, each controlling the exchange of materials specific to their functions.
What is found around the cell and lets materials in and out of the cell?
A cell membrane surrounds all cells and controls the movement of substances.
How does the permeability of the cell wall differ to that shown by the cell membrane?
The cell wall is a rigid structure found in plants, fungi, and some bacteria that provides support and protection to the cell. It is permeable to water and small molecules, allowing for communication between cells. The cell membrane, on the other hand, is a fluid phospholipid bilayer that surrounds all cells and controls the passage of substances in and out of the cell, being selectively permeable.
What does the cell membrane do that the cell wall does not?
The cell wall is a rigid structure that allows plants to hold their upright shape, and is only present in plants. The cell membrane is a selectively permeable membrane that is present in both plant and animal cells, and regulates what enters and exits the actual cytoplasm of the cell, not including particles that can pass through it unaided (like water, which moves in and out with the gradient).
How do cell wall and cell membrane differ?
A cell wall supports membrane , gives it a shape and protects it but, it is not present in all cells like it is not present in the animal and it is made of cellulose and cell membrane regulates what enters and leaves the cell so in other words it is selectively permeable and cell membrane is present in all the cells and it is made up of lipid bilayer.
What is a cell membrane that is selectivly permeable?
A cell membrane is found on both plant and animal cells it selectively chooses what substances may enter or leave the cell. Hence the term selectively permeable. For a more advanced explanation I recommend you research protein icebergs and the different types of transport a membrane can take part in. Example active transport

Which structure is in both plant cells and animal cells controls the passage of substances into and out of cells?
The cell membrane is the structure found in both plant and animal cells that controls the passage of substances into and out of cells. It is a selectively permeable barrier that regulates the movement of molecules such as nutrients, ions, and waste products.
Is a cell membrane in the plant cell or animal cell or both?
The cell membrane (also called the plasma membrane, plasmalemma, or "phospholipid bilayer") is a selectively permeable lipid bilayer found in all cells. Yeah for wikipedia.

Difference between plasma membrane and cell wall?
wikipedia " plasma membrane" the membrane is thin bi-lipid (two-fat) layer that blocks out water the cell wall is a rigid cube like structure that surrounds a plant cell and gives it rigidity jd
What is a good slogan for the cell membrane?
1)GO INSANE FOR THE CELL MEMBRANE! 2)I am one but part of two, I can always be found in you 3)Whats in your brain? Why its a cell membrane!
2 examples of partially permeable membranes?
A selectively permeable membrane is most often attributed to the cell membrane (plasma membrane) of cells. It is constructed of nonpolar phospholipids that will not dissolve many substances, like ions or large molecules. There are carrier proteins embedded in the membrane that allow only certain substances through.
In what way are cell membranes selectively permeable?
Cell membranes are selectively permeable because they allow certain substances to pass through while blocking others. This selectivity is achieved through the presence of proteins and channels that regulate the movement of specific molecules into and out of the cell. The lipid bilayer structure of the membrane also plays a role in determining which substances can cross based on their size, charge, and solubility.
