In endocytosis, transported substances are enclosed in vesicles formed from the plasma membrane, which do physically cross the plasma membrane. These vesicles then transport the substances into the cell.

Of course it is! Didn't you get your Ph.D. in Nuclear Physics?
Glucose is carried through the circulation in the blood plasma.
In plasma, iron is transported bound to a protein called transferrin. Transferrin helps to deliver iron to cells throughout the body, where it is necessary for various biological functions.
Nutrients are transported in the plasma because they need to be carried throughout the body to reach various tissues and organs where they are needed for energy production, growth, and maintenance. The plasma is the fluid component of blood that allows for the efficient circulation of nutrients to different parts of the body.

Yes, it is attached to the red blood cells which travels around the body via the plasma.
The plasma membrane allows materials to be transported in and out for function. lol . honestly idk
Triacylglycerols are packaged into lipoproteins as they are too large and hydrophobic to be transported in plasma.
