Why cant an optical microscope be used to see a plasma membrane?
An optical microscope cannot be used to see a plasma membrane because the plasma membrane is composed of lipid bilayers that are too thin to be resolved by the limited resolution of an optical microscope. Additionally, the plasma membrane is transparent and lacks sufficient contrast for visualization using an optical microscope. Specialized techniques such as electron microscopy or fluorescence microscopy are better suited for imaging the plasma membrane.
How is the cell membrane facilitated diffusion transported?
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.
What kind of Bacteria moves by forming slime and using a wave like motion of their plasma membrane?
The answer us wavalactios bacterium
The process that utilizes a transporter to move materials across the plasma membrane against the concertration gradient using ATP?
diffusion
Is chloroplast a feature of the plasma membrane?
No, it is an organelle found inside plant cells. These produce energy for the plant using sunlight.
What term describes the structure of a cell plasma membrane because of its oily nature and embedded proteins?
The term used to describe the plasma membrane because of it's oily nature and embedded proteins is the fluid-mosaic model.The plasma membrane that surrounds each cell has two layers of phospholipids (fat with phosphorous attached).Each phospholipid molecule has a head that is attracted to water (hydrophilic) and a tail that repels water (hydrophobic) . Both the layers of the plasma membrane have the hydrophilic ends pointing to the outside forming the outer layer of the plasma membrane and the hydrophobic tails pointing inside and forming the inner layer of the plasma membrane.Proteins and substances such as cholesterol become embedded in the bi-layer of the plasma membrane giving it a mosaic look.At body temperature the plasma membrane has a liquid consistency like the vegetable oil and proteins and other substances are able to move across the plasma membrane. Due to this reason the plasma membrane is described using the term fluid-mosaic model.
What happens to a cell during the exocytosis?
It reorganizes its cytoskeleton to reposition its secretory vesicles at the plasma membrane. The vesicles then fuse to the plasma membrane using a complex interaction between proteins of the vesicle membrane and proteins of the cell membrane, and a realignment of the lipids of the membranes. This creates a fusion pore, which rapidly expands to expose the vesicle contents to the extracellular milieu. This releases the vesicle contents into the extracellular space.

How do you isolate a membrane protein in the lab?
One method that researchers developed to separate proteins is to use detergents.Detergents are small amphipathic molecules that tend to form in water.detergents break up plasma membranes, they coat hydrophobic portions of membrane proteins and phospholipids.treating a plasma membrane with a detergent is an effective way to isolate membrane proteins so they can be purified and studied in detail
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
When a cell uses energy to transport a particle through its plasma membrane toward the side of higher concentration the cell is using?
Free Garden Valley
