Plant Transport Systems

Study Notes

Xylem: Transports water and dissolved nutrients from roots to leaves
- Water Uptake: Roots absorb water from the soil and move it upwards through xylem
- Transpiration: Water evaporates from leaves, creating a continuous flow pulling more water from roots
- Nutrient Transport: Minerals and nutrients dissolved in water are carried to the rest of the plant
Phloem: Moves sugars, amino acids, and other organic compounds from leaves to roots and other parts
- Photosynthesis: Sugars produced in the leaves are transported to other areas of the plant
- Storage: Excess sugars and nutrients can be stored in roots, stems, and other tissues for later use
- Nutrient Distribution: Organic nutrients, like amino acids, are distributed from leaves to growing regions
Stomata: Tiny pores on leaves that facilitate gas exchange
- Allow for the exchange of gases like oxygen and carbon dioxide

Circulatory System: Uses the heart to pump blood through blood vessels
- Heart: Central pump that circulates blood throughout the body
- Arteries: Carry oxygen-rich blood away from the heart to the body's tissues
- Veins: Return deoxygenated blood back to the heart for reoxygenation in the lungs
- Capillaries: Smallest blood vessels that allow for exchange of gases, nutrients, and waste between blood and tissues
Respiratory System: Responsible for gas exchange in the body
- Inhale: Air is drawn into the lungs through the nose and mouth
- Gas Exchange: Oxygen is absorbed into the bloodstream and carbon dioxide is expelled
- Exhale: Used air is expelled from the body through the nose and mouth
Digestive System: Absorbs nutrients from food into the bloodstream
- Nutrients are distributed to cells throughout the body

Nutrient transport is essential for the survival and growth of all living organisms
Plants use xylem and phloem to transport water, nutrients, and organic compounds
Animal circulatory and respiratory systems work together to distribute oxygen, nutrients, and remove waste
