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.

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.

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.

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.

Lymph nodes

Red blood cells

Arteries, veins, capillaries

Platelets

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.

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.

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.

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.

Plants adapt their transport systems by modifying xylem and phloem structures based on environmental conditions.

Plants do not change their transport systems regardless of the environment.

Plants use only roots for nutrient transport in all conditions.

Plants rely solely on water availability for transport.

Open circulatory systems are found only in mammals, while closed systems are found in all other animals.

Open circulatory systems lack blood vessels, while closed circulatory systems have blood confined to vessels.

Closed circulatory systems allow blood to flow freely in the body cavity, while open systems do not.

Open circulatory systems have blood vessels, while closed circulatory systems lack them.

Animals regulate body temperature by adjusting blood flow through vasodilation and vasoconstriction.

Animals maintain temperature by increasing metabolic rate only.

Animals use external heat sources to control body temperature.

Animals regulate temperature by changing their fur color.

Soil type and pH

Plant species and age

Nutrient levels in the soil

Temperature, humidity, wind speed, light intensity, and soil moisture.

Nutrients are absorbed only through the leaves.

Organic nutrients are moved through the roots only.

Water and minerals are transported exclusively by phloem.

Nutrient transport in plants occurs through xylem for water and minerals, and phloem for organic nutrients.
