Quiz 6-2 Resp and Photosynthesis Per 1

Leaves are part of a plant’s shoot system. The xylem tissue in leaves transports —

• the bacteria needed for nitrogen fixation in root nodules
• the wax required to coat the surface of actively growing tissue
•  the water and minerals that are absorbed by the roots
• the oxygen that regulates the rate of carbohydrate production

Which of the following correctly describes how a diagram of cellular respiration would differ from a diagram of photosynthesis?

• The cellular-respiration diagram would show electromagnetic waves as the final product.
• The cellular-respiration diagram would show glucose as the main source of energy.
• The cellular-respiration diagram would show energy stored in large protein molecules.
• The cellular-respiration diagram would show water as the main source of chemical energy.

Both euglena and cyanobacteria are photosynthetic unicellular organisms found in pond water. The feature that distinguishes euglena from cyanobacteria is the —

• ability to maintain homeostasis
• presence of ribosomes
• ability to reproduce
•  presence of a nuclear membrane

Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as —

• geotropism
• thigmotropism
• phototropism
• photosynthesis

Which molecule synthesized by plants is a major source of energy for cellular processes in both plants and animals? Note: Be sure to memorize the equations for photosynthesis and its opposite - cellular respiration.

• Wax

• Nucleic acid

• Glucose

• Chlorophyll

Scientists conducted an investigation to study the possible effects of air pollution on chlorophyll a and chlorophyll b in plants. The scientists gathered plants from polluted areas and unpolluted areas and then measured the presence of chlorophyll in 50 mg of plant leaves. The results are shown in the graph. Which inference do these data support?

• Gene expression for chlorophyll is not affected by pollution.

• Plants in polluted areas can adapt in order to survive.

• Photosynthesis decreases in response to air pollution.

• Cellular respiration increases in plants in polluted areas.

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes? Note: Be sure you have these two equations memorized.

• Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.

• Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.

• Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

• Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?

• The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.

• The products of photosynthesis combine with the reactants in cellular respiration to remove ATP from cells.

• The products of photosynthesis inhibit the reactants in cellular respiration in the presence of light.

• The products of photosynthesis change the structure of the reactants in cellular respiration in the presence of light.

• The cellular-respiration diagram would show energy stored in large protein molecules.

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the xylem

• It's made during a chemical reaction in the stem

• The flowers capture water and deliver it to the leaves
