Water for Plants and Transpiration Quiz

Explain how water is transported from the roots to the leaves in plants.

• Absorption through stomata

• Transpiration through xylem vessels

• Evaporation through roots

• Photosynthesis through phloem vessels

How do the roots of a plant contribute to water uptake?

• Roots excrete excess water from the plant

• Roots release water into the soil through specialized structures

• Roots have no role in water uptake

• Roots absorb water from the soil through specialized structures and transport tissues.

Discuss the role of root hairs in the absorption of water by plants.

• Root hairs provide structural support to the plant

• Root hairs store excess water in plants

• Root hairs increase the surface area of the roots, allowing for more efficient absorption of water and nutrients from the soil.

• Root hairs help in the process of photosynthesis in plants

What are the factors that affect the rate of transpiration in plants?

• Soil color, plant height, and leaf shape

• Type of pot, fertilizer used, and time of day

• Number of petals, stem length, and flower color

• Temperature, humidity, wind, light intensity, and water availability

Explain how temperature and humidity influence the transpiration rate in plants.

• Temperature and humidity can affect the rate of transpiration in plants by influencing the opening and closing of stomata on the leaves.

• Temperature and humidity have no impact on transpiration in plants

• Transpiration rate in plants is solely determined by the amount of water in the soil

• Transpiration rate in plants is only influenced by the color of the leaves

Why is water important for the growth of plants?

• Water provides shade for the plants

• Water helps in attracting pollinators to the plants

• Plants need water to build their stems and leaves

• Water helps in photosynthesis and nutrient absorption.

Discuss the significance of water in the process of photosynthesis in plants.

• Water is only needed for the process of transpiration, not for photosynthesis

• Water is essential for the process of photosynthesis as it is one of the reactants in the light-dependent reactions.

• Water is not important for photosynthesis, only sunlight is needed

• Plants can perform photosynthesis without water by using other liquids

What is the mechanism of transpiration in plants?

• Through the flowers

• Through the stomata in its leaves

• Through the stem

• Through the roots

Explain how the stomata and the process of evaporation contribute to transpiration in plants.

• Stomata open to conserve water and reduce transpiration.

• Stomata absorb water and release oxygen, reducing transpiration.

• Evaporation occurs through the roots, not the stomata, decreasing transpiration.

• Stomata allow water to evaporate and create a negative pressure, leading to transpiration.

Remember when you put the celery in the water? What happened to the water level by the next day?

• The level dropped A LOT, because the celery sucked it up.

• The level stayed the same, because the celery was dead.

• The level dropped a little, because of evaporation.
