Study Notes
Reproduction Overview
- Asexual reproduction produces offspring genetically identical to the parent. Methods include budding, fission, and fragmentation.
- Sexual reproduction combines genetic material from two parents, creating genetic diversity. A zygote forms.
- Asexual reproduction types include binary fission (division into two identical cells), budding (new organism from a bud), fragmentation (breaking into fragments that grow), and vegetative propagation (new plants from vegetative parts).
- Spore formation results in new individuals from spores (common in fungi). Self-pollination involves pollen fertilizing ovules within the same flower, while cross-pollination involves pollen transfer between different plants.
Ecosystem Function and Biodiversity
- Ecosystem function influences ecological balance. Species roles are essential (e.g., pollinators).
- Biodiversity is crucial for healthy ecosystems.
Summary of Nutrient Procurement and Processing
- Nutrients are substances for organism growth and maintenance.
- Autotrophs produce food using sunlight and chemicals, while heterotrophs obtain food by consuming other organisms.
Plant Nutrition
- Plants absorb nutrients from water through roots and atmospheric carbon dioxide.
- Plant chemical composition is mainly water (80-90%).
- Root hairs increase absorption surface area.
- Phloem transports sugars.
Nutritional Requirements for Plants
- Macronutrients are needed in large amounts (e.g., water, carbon dioxide).
- Micronutrients are required in smaller amounts.
Nutritional Adaptations in Plants
- Symbiotic relationships with microbes (e.g., mycorrhizae) allow plants to gain nutrients and microbes gain resources.
- Some plants are parasitic, absorbing nutrients from hosts.
Animal Nutrition
- Animal nutritional needs include carbohydrates, proteins, and fats.
- Calories measure energy content.
- Organisms use various feeding mechanisms (e.g., substrate feeding, filter feeding).
Gas Exchange and Respiration
- Gas exchange is essential for life; it provides oxygen for metabolism and removes carbon dioxide.
- Diffusion occurs across moist membranes.
- Respiration is the process where organisms use oxygen and produce carbon dioxide.
- Plants and animals have different systems for gas exchange (e.g., stomata, lungs).
Circulatory Systems
- Closed circulatory systems circulate blood within vessels (e.g., humans).
- Open circulatory systems circulate body fluid directly into tissues (e.g., insects).
- Human circulatory system components include the heart, blood, and blood vessels (arteries, veins, capillaries).
- Blood carries oxygen, nutrients, and waste.
- Pulmonary circulation moves deoxygenated blood to lungs for oxygenation.
- Systemic circulation distributes oxygenated blood to tissues.
