P5 Science TT1 Revision Quiz

What is the main function of the plant transport system?

• To facilitate gas exchange with the environment.

• To store energy for photosynthesis.

• To provide structural support to the plant.

• To transport water, nutrients, and sugars throughout the plant.

Name the two main types of transport tissues in plants.

• xylem and phloem

• stomata and cuticle

• roots and leaves

• chloroplast and mitochondria

How do plants absorb water from the soil?

• Plants absorb water through their leaves during photosynthesis.

• Plants absorb water from the soil through their roots.

• Plants take in water through their flowers.

• Plants extract water from the air using their stems.

What is the role of xylem in plants?

• To facilitate photosynthesis in the leaves.

• To transport sugars from the leaves to the roots.

• The role of xylem in plants is to transport water and minerals from the roots to the leaves and provide structural support.

• To store food and nutrients in the roots.

What is the function of phloem in the plant transport system?

• To provide structural support to the plant.

• To store energy in the form of starch.

• To transport water from roots to leaves.

• The function of phloem is to transport organic nutrients throughout the plant.

How does the circulatory system benefit the body?

• It produces hormones for growth and development.

• It provides insulation to maintain body temperature.

• The circulatory system benefits the body by delivering essential substances to cells and removing waste.

• It helps in digestion by breaking down food.

What are the main components of the human circulatory system?

• Lungs, trachea, and diaphragm

• Heart, blood vessels, and blood

• Brain, spinal cord, and nerves

• Kidneys, liver, and stomach

What is the function of the heart in the circulatory system?

• The heart produces hormones for the circulatory system.

• The heart filters blood in the circulatory system.

• The heart functions as a pump in the circulatory system.

• The heart stores oxygen for the circulatory system.

How does blood flow through the heart?

• Blood moves from the right ventricle to the left atrium before going to the body.

• Blood flows through the heart from the body to the right atrium, to the right ventricle, to the lungs, to the left atrium, to the left ventricle, and finally to the body.

• Blood circulates directly from the lungs to the left ventricle only.

• Blood flows from the left atrium to the right ventricle, then to the body.

What is the difference between arteries and veins?

• Arteries transport oxygenated blood; veins transport deoxygenated blood.

• Veins transport oxygenated blood; arteries transport deoxygenated blood.

• Arteries are thinner than veins; veins are thicker than arteries.

• Arteries carry blood away from the heart; veins carry blood towards the heart.
