Bio 1 Structure and Function of the Cell

Cells are highly organized units that contain specialized structures called                           .

• organelles      

• organisms

• cytoplasm

• organs

Everything within the cell that is situated between the nucleus and the cell membrane is collectively referred to as                                  .

• organelles

• cytoplasm       

• systems

• organisms      

When placed in water, phospholipids line up with their                                            heads facing the water.

• hydrophilic     

• carbohydrate

• protein

• hydrophobic

In fungi, cell walls are composed of                           .

• chitin

• cellulose

• protein

• lipid

Small cells have                                                surface area for their volume of cytoplasm than large cells.

• less

• equal

• more

In plants, cell walls are composed of                                               .

• cellulose

• chitin

• starch

• glycogen

_______________________proteins contain pores that allow certain substances, such as ions, to pass through the membrane.

• Channel

• peripheral

• active

All cells are only produced from pre-existing cells is part of the __________________

Some integral proteins bind to a substance on one side of the membrane and                                       .

• transport it in out out of the cell

• dissolve it

• modify it

Cells are the smallest unit that is able to _____________________.
