Food, urea, hormones, ions, carbon dioxide, antibodies, plasma proteins and other substances dissolved in water.
'
Also, ions of sodium, potassium, calcium, chloride and hydrogen carbonate are present.
'
Proteins such as fibrinogen (needed for clotting), globulins (include the antibodies which fight against bacteria) and albumin are all present and important parts of the plasma.
in my anatomy book it states "it provides a transport medium for solutes and formed elements" i hope this helps later
Channel Protein.
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.
Ion moving against a concentration gradient
When oxygen enters the bloodstream through the lungs it generally binds to red blood cells (more specifically the hemoglobin within red blood cells), which are carried along within the plasma. While some unbound oxygen may become diffused inside the plasma itself it is not the primary or intended mean of oxygen transport throughout the body. In short, plasma doesn't carry oxygen, but instead carries the cells that carry oxygen.
The membranes around cells and even around some organelles do not allow much to go in and out. If the substance is too large, it can't move in without help. If the charge is 'incorrect', it needs help as well.
Passive transport occurs inly with plasma membrane.
Diffusion
Plasma-It carries fibrinogens Fibrinogens-Material necessary for blood clotting
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
No, this is because the transport of K and Na ion across the plasma membrane require active transport and this require ATP.

The transport vesicle.
the plasma membrane.
They allow movement of salts and sugars through the plasma membrane
