Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
Its too large
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Proteins are to large or Oxygen is much smaller than a protein.
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.

Water molecules freely diffuse across a semipermeable membrane.
Oxygen molecules diffuse across the membrane.

Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.

Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.
Oxygen is a small, non-polar molecule that can passively diffuse across the lipid bilayer of a cell membrane. Proteins, on the other hand, are larger and more complex molecules that cannot pass through the hydrophobic core of the membrane. Instead, proteins are transported into or out of cells through specific channels or transporters.
