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 during cellular respiration and stored during photosynthesis.

Carbon dioxide and water released by cellular respiration are used in photosynthesis.

Photosynthesis releases the energy that is stored during the process of cellular respiration.

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

What is the correct equation for cellular respiration?

6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

6CO₂+ 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

The energy carrier that the cell uses to power its day to day activities is

ATP

NADH

FADH₂

glucose

Which of the following is the correct equation for PHOTOSYNTHESIS?

Light and 6CO₂ + 6H₂0 --> C₆H₁₂O₆ + 6O₂

6CO₂+ C₆H₁₂O₆ + 6H₂O --> 6O₂+ light

Light and 6O₂ +6H₂O --> 6CO₂+ C₆H₁₂O₆

6CO₂+ 6O₂ + 6H₂O --> Light+ C₆H₁₂O₆

Which organelle from the plant cell is primarily responsible for converting sunlight to energy?

Mitochonria

Nucleus

Vacuole

Chloroplast

Chloroplasts are...

Structures of animal cells to produce ATP

Organelles where lipids are elaborated

Specialized structures of plants where glucose is made

Waste organelle of plants

Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period.
Which of the following statements best explains Mike’s observations?

Cells decompose most quickly under the most intense light.

Water evaporates from plants faster under the most intense light.

Photosynthesis occurs at the highest rate under the most intense light.

Gases in the leaves of plants expand most under the most intense light

Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?

photosynthesis

lactic acid fermentation

aerobic respiration

alcoholic fermentation

Jake conducted an experiment with four bean plants. They were placed next to one another on a sunny windowsill. He gave each plant equal amounts of a different type of water. The plants were given tap water, distilled water, flavored water, or carbonated water. He made the following observations after three weeks. Based on his results, Jake concluded that tap water is not good for plants. How can Jake change his experimental design to improve the validity of his results?

carry out multiple trials, and increase the number of plants that are given each type of water

establish a control group that includes different types of plants

establish another dependent variable to generate more data

carry out multiple trials that include fewer plants, and increase the types of water given to the plants

10.

Terrestrial plants have stomata on the surface of their leaves. Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants?

Water enters the plant through the surface of the leaf for transpiration

Gases for photosynthesis are exchanged through the surface of the leaf.

Energy for cellular reproduction is absorbed through the surface of the leaf.

Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction.

11.

Stomata

tiny holes in the leaves of a plant that allow gases to enter or leave the plant

living things

a plant part that carries out photosynthesis to make food for the plant

the process in which plants use energy from the sun to make their own food

12.

In what part of the plant does photosynthesis occur?

Xylem

Root

Stem

Leaf

13.

The loss of water through a plants' leaves is called...

transpiration

photosynthesis

chlorophyll

cellular respiration

14.

The diagram below shows a cross section of a plant leaf. How does the structure marked X contribute to the survival of the plant?

It allows the intake of gases necessary for photosynthesis.

It allows the intake of minerals necessary for plant growth.

It allows the intake of sunlight necessary for ATP production.

It allows the intake of sugars necessary for plant reproduction.

15.

The diagram represents a flower, the reproductive structure of some plants. Which structure is represented by the letter A in the diagram?

the stamen, a male structure which produces pollen

the stigma, a female structure which collects pollen and passes it to the ovary

the sepal, a modified leaf used for protection of the flower

the petals, decorative structures which attract pollinators

16.

Plant cells that are specialized for cell division are most likely found in what part of the plant?

root tips

leaf epidermis

stem epidermis

vascular tissue

17.

In which way are photosynthesis and cellular respiration different?

Cellular respiration stores ATP, while photosynthesis releases ATP.

Cellular respiration produces oxygen, while photosynthesis uses oxygen.

Photosynthesis releases energy, while cellular respiration stores energy.

Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

18.

What are the parts of the ATP molecule?

adenine, thylakoids, stroma

stroma, grana, chlorophyll

adenine, ribose, phosphate groups

NADH, NAHPH, FADH
