Study Notes
Gas Exchange and Transport
- Our bodies utilize oxygen to create energy from nutrients.
- Land animals use lungs for oxygen and carbon dioxide exchange.
- Fish use gills to obtain dissolved oxygen from water.
- Oxygen is transported to cells, and carbon dioxide is removed through the heart.
Plant Respiration
- Plants breathe through stomata in leaves, lenticels, and root hairs.
- Stomata are openings on leaves and other plant parts.
- Guard cells control the opening and closing of stomata.
- Lenticels are openings in the outer surfaces of woody plant parts.
Respiratory System
- The respiratory and cardiovascular systems work together for homeostasis.
- The circulatory system transports blood and other materials.
- The respiratory system facilitates gas exchange (oxygen and carbon dioxide).
Cardiovascular System
- Blood vessels transport blood consisting of arteries, veins, and capillaries.
- Arteries carry blood away from the heart with thick walls to withstand high pressure.
- Veins carry blood back to the heart with thinner walls and valves to prevent backflow.
- Capillaries are the smallest blood vessels for material exchange between cells.
- The heart is a muscular pump, driving blood circulation.
- The atria are receiving chambers, while ventricles are the pumping chambers.
Genetics
- Traits are passed down through genes from parents to offspring.
- Genes are sections of DNA.
- Alleles are variations of a gene, and their combinations form genotypes.
- Some genes are dominant, masking recessive traits.
- Some traits are sex-linked, expressed differently in different sexes.
Extinction
- A species is considered extinct when its entire population is gone.
- Mass extinctions occur when numerous species go extinct within a short period.
- Notable extinction events include the Ordovician-Silurian, Late Devonian, Permian-Triassic, Triassic-Jurassic, and Cretaceous-Tertiary.
Photosynthesis
- Plants use light energy to produce food through photosynthesis.
- Photosynthesis occurs in chloroplasts containing chlorophyll.
- Chlorophyll absorbs light energy and converts it to glucose.
- Stomata are pores that regulate gas exchange.
Cellular Respiration
- Cellular respiration is a process where cells break down nutrients (like glucose) in the presence of oxygen to produce energy (ATP).
- Aerobic respiration uses oxygen, yielding more ATP compared to anaerobic respiration (occurs without oxygen).
- Glycolysis, the Krebs Cycle, and the Electron Transport Chain are stages in respiration.
