Study Notes

General Biology II - Summative Test

Plant Extinction and Pollinators: Loss of a specific pollinator could lead to plant extinction. Plants may not adapt to substitute pollinators.
Vegetative Propagation: This method allows for rapid plant colonization in stable environments. It doesn't increase genetic diversity and requires less energy than sexual reproduction.
Climate Change and Plant Reproduction: Changing environmental cues, especially for flowering, can alter the reproductive success of plants, potentially reducing it.
Flower Color and Pollination: Multiple flower colors in a species attract a greater range of pollinators, potentially improving reproductive success.
External Fertilization and Amphibians: This reproductive strategy is better suited for aquatic environments, boosting fertilization chances.
Viviparity vs. Oviparity: Viviparity in mammals provides better protection for developing embryos compared to oviparity.
Sexual Selection: Favors traits increasing mating success, thereby influencing reproductive success in animals.
Hermaphroditism: This reproductive strategy allows for self-fertilization, increasing reproductive flexibility.
Sexual Reproduction in Animals: Involves gametes from two parents, resulting in genetically diverse offspring.
Asexual Reproduction in Animals (Budding): Hydra reproduce asexually by budding.
Parthenogenesis: Embryo development without fertilization.
Oviparity: Offspring develop outside the mother's body.
Flower Parts: Anther produces pollen; Ovary; Sepals; Stigma
Asexual Reproduction in Plants (Vegetative Propagation): A type of asexual reproduction in plants.
Seed Germination: The process of a seed developing into a new plant.
Plant Parts: Leaves absorb water and nutrients; Roots; Xylem transports water ; Phloem transports food
Photosynthesis Products: Glucose and oxygen
Plant Gas Exchange Process: Respiration; Stomata, guard cells, and transpiration
Animal Digestive System: Breaks down food and absorbs nutrients
Herbivores vs. Carnivores: Herbivores eat plants exclusively; Carnivores eat meat.
Digestive enzymes: Break down complex molecules into simpler ones.
Respiration & Hemoglobin: Hemoglobin binds and transports oxygen in the blood.
Respiratory Systems: Fish use gills for gas exchange; Diaphragm facilitates breathing in mammals
Plant Photosynthesis & Oxygen: Plants release oxygen, crucial for atmospheric oxygen levels.
Plant Gas Exchange Factors: Light intensity, affects the exchange of gases

Countercurrent Exchange in Fish Gills: Maximizes oxygen uptake.
Blood Vessel Damage and Transport: Can decrease the transport efficiency in animals with damaged blood vessels.
High-Altitude Environments and Circulation: Can trigger increased red blood cell production.
Blood Vessels: Arteries carry blood away from the heart; Veins return blood to the heart.
Blood Components: Red blood cells carry oxygen.
Water Balance in Animals: Kidneys filter blood and form urine, maintaining water balance.
Freshwater Fish & Ion Balance: Freshwater fish maintain ion balance by absorbing ions through active transport.
Water Loss in Plants: Wilting can occur if a plant loses more water than it absorbs, e.g., in dry conditions
Feedback Mechanisms in Animals: Positive feedback enhances a process, while negative feedback reverses a process.
Plant Responses & Growth: Tropisms (e.g., phototropism, geotropism) relate to directional growth responses.
Homeostasis & Temperature Regulation: The hypothalamus regulates body temperature; sweating, shivering act to regulate body temperature.
Circulatory System & Waste Products: Capillaries are crucial in removing waste products from tissues.
Hormones in Animals: Regulate bodily functions.
Water Balance & Dehydration: Loss of water through sweat can lead to dehydration.
