Understanding Potometers in Plant Science

What is the primary purpose of using a potometer in plant studies?

• To measure the rate of photosynthesis

• To measure the rate of transpiration

• To measure the growth rate of plants

• To measure the nutrient uptake in plants

What is the first step in setting up a potometer?

• Filling the potometer with water

• Cutting the plant shoot underwater

• Attaching the plant shoot to the potometer

• Sealing all joints with petroleum jelly

Which of the following is a common error when using a potometer?

• Using a plant shoot with too many leaves

• Not sealing the joints properly

• Using distilled water

• Measuring the water uptake too frequently

Why is it important to cut the plant shoot underwater when setting up a potometer?

• To prevent air bubbles from entering the xylem

• To ensure the shoot is clean

• To hydrate the plant shoot

• To remove excess leaves

What safety precaution should be taken when using a potometer?

• Wear gloves to protect from plant sap

• Ensure the potometer is placed on a stable surface

• Use a fan to dry the leaves quickly

• Keep the potometer in direct sunlight

How can you ensure that the potometer is airtight?

• By using a rubber stopper

• By sealing all joints with petroleum jelly

• By using a plastic bag

• By using a metal clamp

What is the role of the reservoir in a potometer setup?

• To provide nutrients to the plant

• To allow resetting of the water level

• To measure the temperature

• To hold the plant shoot in place

Which of the following conditions can affect the accuracy of a potometer?

• Temperature fluctuations

• Consistent light exposure

• Using a single type of plant

• Keeping the potometer indoors

What is the main reason for using petroleum jelly in a potometer setup?

• To lubricate the plant shoot

• To prevent water loss through evaporation

• To enhance the plant's growth

• To make the setup look neat
