Which of the following structures in the plant is responsible for carrying water and nutrients from the roots to the rest of the plant?

• Stomata

• Xylem

• Phloem

• Chloroplasts

How does the process of transpiration cause drops of water to appear inside a plastic bag tied around a plant?

• The plant releases excess water through its leaves, which condenses on the inside of the plastic bag.

• The plastic bag traps moisture around the plant, causing it to sweat and produce drops of water.

• The plastic bag creates a humid environment, causing the plant to release more water than usual through transpiration.

• The drops of water are caused by a chemical reaction between the plastic and the plant's natural oils.

How do plants transport nutrients from one part of the plant to another?

• Through photosynthesis

• Through transpiration

• Through respiration

• Through phloem

If the stem of the convolvulus plant is cut, what will happen to the leaves above the cut?

• The leaves die because the cut stem prevents the transport of nutrients.
• The leaves die because the cut stem prevents the transport of water.
• The leaves die because the cut stem prevents the plant from producing energy.
• The leaves die because the cut stem exposes them to harmful chemicals.

Three identical beakers of pondweed were left in darkness, dim light, or intense light for an hour. Then the oxygen in each beaker was measured using an oxygen sensor. Describe how the amount of oxygen in the water was affected by the light intensity.

• The amount of oxygen in the beaker in dim light was greater than in intense light.
• The amount of oxygen in the beaker in intense light was greater than in dim light.
• The amount of oxygen in the beaker in darkness was greater than in dim light.
• The amount of oxygen in all three beakers was the same.

Three identical beakers of pondweed were left in darkness, dim light, or intense light for an hour. Then the oxygen in each beaker was measured using an oxygen sensor. How would the light intensity affect the amount of CO2 in the water?

• Intense light would decrease the amount of CO2 in the water.
• Dim light would decrease the amount of CO2 in the water.
• Darkness would decrease the amount of CO2 in the water.
• Light intensity would not affect the amount of CO2 in the water.

Pondweed were placed in two identical apparatus. A chemical was added to the water in apparatus B to increase the CO2 concentration in water. Bubbles appeared in both test tubes. Suggest the gas.

• Oxygen
• Carbon dioxide
• Nitrogen
• Hydrogen

When oil is spread on leaves, it stops them from losing water. Two identical plants had different leaf surfaces covered in oil. They were weighed at the start and after 1 day to see how much water they have lost. explain why their pots were covered in plastic bags?

• The plastic bags were used to prevent water loss through evaporation.
• The plastic bags were used to create a closed system to isolate water loss through transpiration.
• The plastic bags were used to increase humidity around the plants.
• The plastic bags were used to create a greenhouse effect.
