Study Notes
Photosynthesis Components
- Chlorophyll is essential for photosynthesis.
- Chloroplasts contain chlorophyll.
- Carbon dioxide is absorbed through stomata on leaves, stems, and roots.
- Guard cells control the opening and closing of stomata for gas exchange.
- Sunlight is essential for photosynthesis.
Plant Transport Systems
- Water and minerals are transported through the xylem.
- Products of photosynthesis are transported through the phloem.
- Water moves from the soil into the roots due to a difference in ion concentration.
- Transpiration, the loss of water vapor from leaves, helps pull water upwards.
Excretion in Humans
- Excretion is the removal of harmful metabolic wastes from the body.
- The excretory system in humans includes kidneys, ureters, bladder, and urethra.
- Kidneys filter waste products from blood, producing urine.
- Urea and uric acid are nitrogenous waste products removed by the kidneys.
Key Facts
- Aerobic respiration creates more energy than anaerobic respiration.
- Plants use the vascular tissue, xylem, and phloem for transport.
- Plants store waste in vacuoles, gums, and resins.
- Fallen leaves can also remove waste products from trees.
