Photosynthesis, Cellular Respiration, Carbon Cycle Review

Plants are producers. This means they take in sunlight, water, and carbon dioxide and convert them into sugar and oxygen. What is the name of this process?

• conservation

• homeostasis

• metabolism

• photosynthesis

What is the correct equation for photosynthesis?

• water + oxygen --> carbon dioxide + glucose

• water + carbon dioxide --> oxygen + light

• water + carbon dioxide --> oxygen + glucose

• water + glucose --> carbon dioxide + energy

One living plant leaf, still attached to the plant, is placed into a cup and covered with water. A light source is placed above the cup, shining into the cup of water so that the leaf receives the light. In moments, bubbles appear at the surface of the plant leaf.

Which statement explains what causes the bubbles to appear?

• Photosynthesis is occurring and bubbles of carbon dioxide gas are being released by the surrounding area and absorbed into the plant leaf.

• Photosynthesis is occurring and bubbles of carbon dioxide gas are being released by the leaf into the surrounding area.

• Photosynthesis is occurring and bubbles of oxygen gas are being released into the surrounding area.

• Photosynthesis is occurring and bubbles of air are entering the water fro the area around the plant.

Margie illustrated the process of photosynthesis, as shown.

Which mistake did she make?

• The arrow for sugar should point away from the plant.

• The arrow for carbon dioxide should point away from the plant.

• The arrows for carbon dioxide and sugar should point away from the plant.

• The arrow for carbon dioxide should point away from the plant, and the arrow for oxygen should point toward the plant.

Which statement describes the role of chlorophyll in the production of food during photosynthesis?

• Chlorophyll combines with nitrogen to make food.

• Chlorophyll converts oxygen and carbon dioxide into food.

• Chlorophyll releases energy from sunlight to produce food and carbon dioxide.

• Chlorophyll absorbs energy from sunlight and converts it into the stored energy in food.

Which statement best explains the process of cellular respiration?

• Glucose and another product are formed when carbon dioxide and water are combined.

• Oxygen and another product are formed when carbon dioxide and water are combined.

• Bonds are broken within the carbon dioxide molecules, providing energy and releasing oxygen.

• Bonds are broken within the glucose molecules, providing energy and releasing carbon dioxide.

What could both add and remove carbon from the atmosphere in the model?

• a car

• a deer

• an insect

• a tree

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which a plant has started to grow. A non-germinating seed is usually dry and a new plant has not yet emerged. The data that she gathered are displayed in the graph.

In addition to carbon dioxide, which of the following should Callie expect the seeds to give off as a waste product from performing cellular respiration?

• glucose

• energy

• water

• oxygen
