membrane lipid which is made up of phospholipids and glycolipids. both phospholipids and glycolipids makes up glycerolipid.
selectively permiable membrane (you might want to double check that though...)
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
Molecule A is likely smaller and more hydrophobic, allowing it to pass through the cell membrane easily via simple diffusion. Molecule B may be larger, polar, or charged, requiring a transporter or channel for passage across the cell membrane.
Phospholipids are the primary type of molecule that forms the cell membrane. They have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to arrange in a bilayer to create the cell membrane.
Endocytosis is the process where a molecule causes the cell membrane to bulge inward, forming a vesicle to bring the molecule inside the cell. This is distinct from exocytosis, which is the process of releasing molecules from a cell by fusing vesicles with the cell membrane and expelling their contents.
The cell membrane contains phospholipids.

This is called endocytosis.
The cell membrane folds around the molecule.
