Plants and their processes22

A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in direct sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?

• The plant will die because it does not have carbon dioxide for photosynthesis.

• The plant will die because it does not have oxygen for photosynthesis.

• The plant will grow faster because it is able to perform aerobic respiration.

• The plant will grow at a slower rate because it requires more water for aerobic respiration.

Opossums are nocturnal which means they are mostly active at night. Which graph provides the most likely representation of the use of glucose, by an opossum's muscle cells over a twenty-four hour period?

• 
• 
• 
• 

Answer explanation

Glucose is going to be used more at midnight.

Students are asked to pair a plant structure to its physiological function as well as give evidence for why that structure is important for the process they describe.

 Anne: The xylem of the plant is needed for reproductive purposes as it attracts pollinators.

 Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves in order to perform cellular respiration.

 Shantal: The cambium is important for photosynthesis because it allows water into the plant which is needed as a reactant for photosynthesis.

 Enrique: The guard cells are needed during transpiration because they open and close to regulate the gases that enter and leave the plant

 Which student correctly described a plant structure, its physiological function, and gave appropriate evidence?

• Anne

• Jamil

• Shantal

• Enrique

Bromothymol blue is a chemical reagent that reacts to the presence of carbon dioxide. Below is a data table that explains how the reagent reacts to different gasses and an image showing test tubes that are a part of a student experiment. What were the actions performed during step X and step Y?

• Step X was adding an aerobic organism into the test tube. Step Y was exhaling into the test tube.

• Step X was exhaling into the test tube. Step Y was adding an aerobic organism into the test tube.

• Step X was adding a plant-like organism into the test tube. Step Y was exhaling into the test tube.

• Step X was exhaling into the test tube. Step Y was adding a plant-like organism into the test tube.

Answer explanation

Carbon dioxide from respiration changed it yellow and oxygen produced through photosynthesis turned it back blue.

Kat has a fish tank with Amazon sword plants and fish native to the Amazon river. Kat began noticing her fish swimming slower as if they were tired. Her fish tank has an indicator for dissolved gas levels, so she decided to look to see if there could be an issue. The following graph depicts the levels of dissolved oxygen and carbon dioxide in the tank. What suggestion would you give Kat that would best help her fish?

• add a light over the tank, so the plants perform photosynthesis

• add food for the fish, so the fish can perform aerobic respiration

• add carbon dioxide to the tank, so the plants can perform anaerobic respiration

• add glucose to the tank, so the plants have more energy available for photosynthesis

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.

 

 

 Which statement describes how photosynthesis and cellular respiration are interrelated?

• Oxygen is produced in cellular respiration and stored during photosynthesis.

• Carbon dioxide and water are released by cellular respiration as products and are used in photosynthesis as reactants.

• Photosynthesis uses glucose that is made from the process of cellular respiration.

• Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

A sperm cell moves its flagella back and forth in order to move through its environment. Which statement describes how this eukaryotic cell transfers energy to the flagellum in order to allow it to move?

• The cell uses photosynthesis to make the glucose needed to create ATP.

• The cell uses the mitochondria to generate high energy proteins that move the flagella.

• The cell produces ATP in the mitochondria and the high energy bonds are used to move the flagella

• The cell mitochondria utilize cellular respiration to generate glucose that gives the flagella energy to move

.  Which statement best explains the importance of the root hairs to the plant?

• Root hairs decrease the need for plants to take in oxygen.

• Root hairs convert minerals into glucose for immediate use by cells.

• Root hairs increase the surface area of the roots for nutrient absorption.

• Root hairs prevent water loss in leaves through transpiration and gas exchange.
