U4_Plant Growth and Water Quiz

How does water affect plant growth?

• Water affects plant growth by providing the necessary hydration for photosynthesis and nutrient absorption.

• Water has no effect on plant growth

• Water causes plants to wilt and die

• Plants can grow without water

What is the process by which water is absorbed by the roots of plants and released as water vapor through the stomata of leaves?

• The process is called photosynthesis.

• The process is called precipitation.

• The process is called transpiration.

• The process is called respiration.

Why are nutrients important for plant growth?

• Nutrients are not important for plant growth, they can survive without them

• Nutrients are important for plant growth, but only for aesthetic purposes

• Plants only need water for growth, nutrients are not necessary

• Nutrients are important for plant growth because they provide essential elements for the plant's metabolic processes, such as photosynthesis, respiration, and growth.

Name one factor that affects plant growth.

• Water

• Music

• Sunlight

• Concrete

What is the green pigment in plants that is responsible for capturing light energy during photosynthesis?

• Carotene

• Melanin

• Hemoglobin

• Chlorophyll

How does the amount of water affect the rate of transpiration in plants?

• Plants transpire faster when there is less water available

• The amount of water has no effect on the rate of transpiration in plants

• The amount of water affects the rate of transpiration in plants. More water availability can increase transpiration rate, while water scarcity can decrease it.

• Transpiration rate is not affected by the amount of water in plants

What are the three primary nutrients that are essential for plant growth?

• Nitrogen, Phosphorus, Potassium

• Calcium, Magnesium, Iron

• Sodium, Chlorine, Sulfur

• Zinc, Copper, Manganese

How does temperature affect plant growth?

• Temperature has no effect on plant growth

• Temperature affects plant growth by influencing the rate of photosynthesis, water absorption, and nutrient uptake. Extreme temperatures can also cause damage to plant cells and tissues.

• Temperature only affects the color of the plants

• Plants grow better in extreme temperatures

What is the role of carbon dioxide in photosynthesis?

• Carbon dioxide inhibits the process of photosynthesis

• Carbon dioxide is not involved in photosynthesis

• Carbon dioxide is used by plants during photosynthesis to produce glucose and oxygen.

• Carbon dioxide is a waste product of photosynthesis
