Study Notes
Plant Transport Systems
-
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
Animal Transport Systems
-
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
Key Takeaways
- 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
