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 are small channels that form across the plasma membranes of adjacent cells?
plasmodesmata
Small pieces of matter even whole cells can be transported across the plasma membrane in what?
vesicle
Which microbes have cell membranes?
Every microbe has cell membranes but only plants have plasma membranes...
What are organisms that have plasma membranes?
Eukaryotes
How plasma membrane diffuse across plasma membrane?
Ions can't diffuse across membranes, they must used channels to transport across

How do larger molecules move across epithelial membranes in the capillaries?
Large molecules are transported across a cell membrane by the process of process of exocytosis. This is when secretory vesicles secretes large molecules by the fusion of vesicles with the plasma membrane.

vesicle
What does plasma membranes do?
Plasma membrane functions to hold the contents of a cell together and separates them from the external environment.Plasma membrane also selectively controls the movement of substances going in or out of the cytoplasm, both actively and passively.
What are the differences between the plasma membrane and other membranes?
plasma membrane and other membranes are the same
Are plasma membranes only found in plant cells?
no animal cells also have plasma membranes
What are eukaroytic cells surrounded by?
cell membranes and plasma membranes
What cells have internal membranes and plasma membranes?
Eukaryotic cells.
What is the main source of chloresterol?
Cholesterol is a waxy steroid of fat that is produced in the liver or intestines. It is used to produce hormones and cell membranes and is transported in the blood plasma of all mammals.
What is an apoplast?
An apoplast is a space outside of a plant's plasma membrane through which water and soluble nutrients are transported across a tissue or organ.
