1. Which process is best illustrated by the diagram? respiration B) photosynthesis C) transpiration D) hydrolysis

2. Base your answer to the following question on the diagram below and on your knowledge of biology. The diagram represents some processes occurring in the leaf of a plant. Which equation illustrates a process of nutrition carried out within the leaf? A) B + D  A + C B) A + C  A + B + D C) B + C  A + D D) A + B + D  B + C

3. Which substances must a green plant obtain from its environment to carry on photosynthesis? A) glucose and water B) oxygen and chlorophyll C) carbon dioxide and water D) carbon dioxide and oxygen

4. Photosynthesis transforms molecules of water and carbon dioxide into molecules of A) carbohydrate and oxygen B) carbohydrate and nitrogen C) polypeptide and oxygen D) polypeptide and nitrogen

5. The diagram below represents a process that occurs in a structure of a specialized cell. Which row in the chart correctly identifies the letters in the diagram? A) 1 B) 2 C) 3 D) 4

6. The diagram below represents the setup for an experiment. Two black paper discs are opposite each other on both sides of each of two leaves This experimental setup would most likely be used to show that A) glucose is necessary for photosynthesis B) protein is a product of photosynthesis C) light is necessary for photosynthesis D) carbon dioxide is a product of photosynthesis

7. What is the major environmental factor limiting the numbers of autotrophs at great depths in the ocean? A) type of seafloor B) amount of light C) availability of minerals D) absence of biotic factors

8. Base your answer to the following question on the information and the diagram below which represents a single-celled organism known as Euglena. This organism is able to carry out both photosynthesis and cellular respiration. Choose one of these processes and write the name of the process you chose below. Using words or chemical symbols, summarize the reaction involved in the process you chose.

Photosynthesis: • carbon dioxide + water  glucose + oxygen • CO2 + H2O + sunlight  C6H12O6 + O2 • Radiant energy is converted into chemical bond energy. Cellular respiration: • glucose + oxygen  carbon dioxide + water + ATP • C6H12O6 + O2  CO2 + H2O + energy • Energy is released from food.
