Midterm Review

What is the formula for photosynthesis?

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• C₆H₁₂O₆ + 6O₂ → Energy +6CO₂ + 6H₂O

• ATP+ 6O₂ → Energy + O2+ 6H₂O

• 6CO₂ + 6H₂O → 6CO₂ + 6H₂O

What characteristic of water causes capillary action, such as water traveling up a plant stem?

• Adhesion

• Solubility

• Hydrogen bonds

• Surface tension

The movement of water across a selectively permeable membrane without the use of any energy is called —

• Diffusion

• Active Transport

• Osmosis

• Endocytosis

Which of the following is NOT a function of proteins?

• Form parts of tissues such as bone and muscle

• Make up antibodies

• Serve as catalysts that control the rate of chemical reactions in the cell

• Store genetic information

Photosynthesis and cellular respiration are often described as existing in a cycle. Which statement best describes why this is true?

• Plants perform only photosynthesis and animals perform cellular respiration.

• Heterotrophs can perform photosynthesis and cellular respiration, where autotrophs can only perform photosynthesis.

• Plants perform only cellular respiration and animal perform photosynthesis.

• Each reaction results in chemical products that are needed as reactants for the other reaction.

According to the cell theory —

• all organisms are composed of tissues

• animals are composed of cells, but plants are not

• new cells arise only from other cells

• the smallest unit of life is an atom
