Photosynthesis and Respiration Review

The diagram below illustrates the movement of materials that is vital for the energy needs of organisms. The process illustrated occurs within

• chloroplast
• mitochonddria
• ribosome
• vacuole

The diagram below represents the setup for an experiment. Two black paper discs opposite each other on both sides of each of two leaves. The experimental setup would most likely be used to show that

• glucose is necessary for photosynthesis
• protein is a product of photosynthesis
• light is necessary of photosynthesis
• carbon dioxide is a product of photosynthesis

Starch molecules present in a maple tree are made from materials that originally entered the tree from the external environment as

• enzymes
• amino acids
• simple sugars
• inorganic compounds

The diagram below represents a photosynthesis. Which set of molecules is best represented by letters A and B?

• A: oxygen and water B: glucose
• A: carbon dioxide and water B: glucose
• A: glucose B: oxygen and water

A cell in the leaf of a corn plant contains more chloroplasts than a cell in the stem of a corn plant. Based on this observation, it can be inferred that, when compared to a cell in the stem, the cell in the leaf

• synthesizes more sugar
• produces fewer proteins
• uses less carbon dioxide

Which process performed by organisms produces oxygen for the aquatic ecosystem?

• respiration
• active transort
• autotrophic nutrition

Name the process represented by the equation.

• photosynthesis
• cellular respiration

Name the molecule represented by the letter X.

• glucose
• ATP
• DNA
• PTA

ATP is a compound that is synthesized when

• chemical bonds between carbon atoms are formed during photosynthesis.
• Energy stored in chemical bonds is released during cellular respiration.
• Energy stored in nitrogen is released, forming amino acids.

The flow of energy through an ecosystem involves many energy transfers. The formula below summarizes the transfer of energy that eventually powers muscle activity. The process of cellular activity is represented by

• Arrow A only
• Arrow B only
• Arrow C only
• Arrows A, B and C
