Remember, the membrane is a fat "soap-bubble" that seperates the water within the cell from the water without.

Why can oxygen diffuse across a cell membrane but a protein?
Its too large
Cells are able to remove large amounts of material using?
Exocytosis.
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.
In what ways have body cells adapted to the task of absorbing and excreting large amounts of materials?
Try this for a basic, high school level, explanation of how cells are adapted to the tasks of absorbing/excreting large amounts of materials: Cell membranes are barriers to the passage of some kinds of substances. Some cells, though, need to absorb and excrete large amounts of materials, so they have adapted by using processes like facilitated diffusion, where transport proteins help certain molecules to pass across cell membranes. Also, the process of active transport, which requires the expenditure of chemical energy supplied by the cell, can move solutes across membranes, even against the direction usually indicated by natural diffusion. Cells use exocytosis to excrete the contents of a membrane vesicle that forms around a capsule of cellular exports, or even "trash" the cell needs to excrete. Cells can also then incorporate the vesicle membrane's components into the cell membrane. By endocytosis, a cell can bring in what it needs, too. The membrane brings a capsule of extra-cellular material which folds into the membrane, forms a vesicle, and then spills its contents into the cytoplasm for a cell to use.
The diagram represents movement of a large molecule across a membrane?
It depends on what is moving across the membrane. Some molecules use transport proteins and the cell would need those embedded in the membrane. Water doesn't need them and it freely moves in and out.
In which process do cells release large amounts of material?
Exocytosis is a process by which a cell releases large amounts of material. In this process a cell takes material into the cell by infolding of the cell membrane.
Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What is rapid movement of large amounts of material downslope?
Landslides

Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
Why can oxygen diffuse across a cell membrane but a protein can?
Its too large
How do large cells move across the cell membrane?
There cannot be large cells inside a cell.
What molecules will move easily across the cell membrane: large proteins, starch, water, or DNA?
It depends on the membrane, but generally water is the only one that will move across unaided. The rest are too large.
What large molecules need help getting across cell membrane?
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
What happens if the particle is too large to get across the membrane?
The cell use something called a protein channel that helps larger particles across the cell membrane.
What is biopoem?
A biopoem is a student's synthesis of large amounts of material in a poem.
