What are the main components of the plant transport system?

• Roots and leaves

• Stems and flowers

• Chloroplasts and mitochondria

• Xylem and phloem

How do xylem and phloem differ in function?

• Xylem transports food; phloem transports air.

• Xylem is responsible for photosynthesis; phloem for respiration.

• Xylem carries nutrients; phloem carries water and minerals.

• Xylem carries water and minerals; phloem carries nutrients.

What role does the stomata play in plant gas exchange?

• Stomata are responsible for photosynthesis in plants.

• Stomata facilitate gas exchange by allowing carbon dioxide in and oxygen out, while also regulating water loss.

• Stomata primarily absorb nutrients from the soil.

• Stomata only allow oxygen to enter the plant.

Describe how water moves through a plant.

• Water is absorbed by leaves and transported to roots.

• Water is stored in the stem and released as needed.

• Water moves through the plant via phloem vessels only.

• Water moves from the roots to the leaves through xylem vessels, driven by transpiration.

What is the primary function of the circulatory system in animals?

• To transport oxygen, nutrients, hormones, and waste products throughout the body.

• To provide structural support to the body.

• To regulate body temperature through sweat production.

• To facilitate digestion and absorption of food.

Name the main types of blood vessels in the animal circulatory system.

• Lymph nodes

• Red blood cells

• Arteries, veins, capillaries

• Platelets

How does oxygen get transported in the blood?

• Oxygen is primarily transported as carbon dioxide in the blood.

• Oxygen is carried by white blood cells to tissues.

• Oxygen is stored in the liver and released into the bloodstream as needed.

• Oxygen is transported in the blood by binding to hemoglobin in red blood cells and being dissolved in plasma.

What is the role of hemoglobin in gas exchange?

• Hemoglobin transports oxygen from the lungs to the body's tissues and carries carbon dioxide from the tissues back to the lungs.

• Hemoglobin regulates body temperature during exercise.

• Hemoglobin is responsible for producing energy in cells.

• Hemoglobin helps in the digestion of food in the stomach.

Explain how nutrients are absorbed in the digestive system of animals.

• Nutrients are absorbed in the large intestine through fiber.

• Nutrients are absorbed directly through the skin into the bloodstream.

• Nutrients are absorbed in the stomach through gastric juices.

• Nutrients are absorbed in the small intestine through the intestinal walls into the bloodstream.

What is transpiration in plants?

• The absorption of nutrients by plant roots.

• The process of photosynthesis in plant leaves.

• The growth of new leaves and branches in plants.

• Transpiration in plants is the release of water vapor from plant leaves into the atmosphere.
