Cellular respiration is called an aerobic process because it requires_____

• exercise

• light

• glucose

• oxygen

Each body cell contains the same genetic information, but can differ in appearance

and size. The diagram below shows three different types of cells found in the human

body.

A. Identify one similarity, other than the genetic information, that these body cells have.

B. Explain why differences in these human body cells are a biological advantage.

A photograph of human cells as seen with a

compound light microscope is shown below. A

cell structure is labeled A.

Structure A is most likely a

• mitochondrion that synthesizes food for the

  cell

• nucleus that is the site of food storage

• nucleus that is responsible for the storage of

  information

• mitochondrion that absorbs energy from the

  Sun

State one way the two molecules could differ that would explain the difference in their ability to pass through

the artificial plant cell membrane.

Answer explanation

— Molecule A is smaller than molecule B.

— Molecule B has an electrical charge.

— They could be different sizes.

— size of the molecule

— One is a sugar/monosaccharide and the other is a starch/polysaccharide.
