Which of the following is TRUE about the sugar molecules in plants?

• The sugar molecules come from the soil and are transported through the roots to the leaves.

• The sugar molecules are one of many sources of food for plants.

• The sugar molecules are made from molecules of water and minerals.

• The sugar molecules are made by the plant and consist of carbon atoms linked to other carbon atoms.

Answer explanation

The correct choice states that sugar molecules are made by the plant through photosynthesis, linking carbon atoms together. This process occurs in the leaves, not from soil or minerals.

Which of the cells above has been placed in a hypertonic solution?

• A. 1

• B. 2

• C. 3

Answer explanation

Cell 1 is in a hypertonic solution because it has shrunk due to water moving out of the cell, indicating a higher solute concentration outside compared to inside the cell.

Molecules that are too large to be moved across a cell membrane can be removed from the cell by?

• Diffusion

• Exocytosis

• Lipid Carriers

• Osmosis

Answer explanation

Exocytosis is the process by which large molecules are expelled from a cell. It involves vesicles fusing with the cell membrane to release their contents outside, making it the correct choice for removing large molecules.

Identify the letter of the choice that best completes the statement or answers the question.

Answer explanation

The correct choice is the one that logically completes the statement or answers the question based on the context provided. It is essential to analyze each option carefully to determine the best fit.

Which of the following could have been the student's hypothesis for this experiment? A. The Elodea will make more bubbles when there is more light.

Answer explanation

The hypothesis A suggests that increased light will lead to more bubbles from Elodea, indicating a relationship between light intensity and photosynthesis rate, which is a valid scientific prediction.

Fill in the blank: The color of light that resulted in the greatest number of bubbles was ________.

• Colorless

• Red

• Blue

• Green

Answer explanation

The colorless light likely provided the most effective wavelength for bubble formation, resulting in the greatest number of bubbles compared to colored light, which may not have had the same effect.

Which statement is true about Elodea?

• The Elodea will make more bubbles in red light.

• The Elodea will make more bubbles in green light.

• The Elodea likes the water.

• The Elodea needs oxygen to do photosynthesis.

Answer explanation

Elodea, a water plant, performs photosynthesis and produces oxygen. It absorbs light most effectively in the green spectrum, leading to more bubble production, indicating higher rates of photosynthesis.

Identify the letter of the choice that best completes the statement or answers the question. The process of cellular respiration.

• A. Is performed only by organisms that are incapable of photosynthesis.

• B. Breaks down food molecules to release stored energy.

• C. Occurs before plants are able to carry out photosynthesis.

• D. Occurs only in animals.

Answer explanation

B is correct because cellular respiration is the process that breaks down food molecules, such as glucose, to release stored energy, which is essential for all living organisms, not just those that cannot photosynthesize.

In the model of photosynthesis, what is Input 1?

• Carbon dioxide

• Oxygen

• Glucose

• Sunlight

Answer explanation

In photosynthesis, Input 1 refers to carbon dioxide, which plants absorb from the atmosphere. This gas is essential for the process, as it combines with sunlight and water to produce glucose and oxygen.

In the model of photosynthesis, what is Input 2?

• Water

• Oxygen

• Glucose

• Sunlight

Answer explanation

In photosynthesis, Input 2 refers to water, which is essential for the process. Water is split to release oxygen and provide electrons for converting sunlight into chemical energy.
