Biology Section B: Form and Functions

Section B: Form and Functions - Summary

• Internal plant and animal structures are intricately designed for survival and function
• Various systems work together to manage essential life processes like nutrition, transport, respiration, excretion, support, movement, reproduction, growth, and coordination/control
• Plant structures (roots, stems, leaves) facilitate nutrient uptake and photosynthesis
• Animal organ systems (digestive, circulatory, nervous) play crucial roles
• Specialization and interdependence of these systems allow organisms to adapt to environments and meet biological needs

Highlights

• Internal Structure: Plants have specialized tissues (xylem, phloem) and animals feature organ systems for specific tasks
• Nutrition: Plants are autotrophic (photosynthesis), animals are heterotrophic (require food intake)
• Transport: Plants use xylem and phloem; animals use circulatory systems for nutrient and gas distribution
• Respiration: Plants and animals use different methods (stomata vs lungs/gills) for gas exchange, crucial for energy production
• Excretion: Waste removal is essential for homeostasis in both kingdoms (Plants: transpiration, Animals: kidneys)
• Support and Movement: Plants have cell walls; animals have skeletons for support and movement
• Reproductive Strategies: Diverse methods (sexual/asexual) in both plants and animals ensure species continuation

Key Insights

• Internal Structures: Plant tissues are specialized (e.g., photosynthesis in chloroplasts, water transport in xylem)
• Animal organ systems break down food (digestion), emphasizing diverse survival strategies
• Nutrition: Autotrophic plants vs. heterotrophic animals - this difference highlights interdependence in ecosystems
• Transport: Movement of water, nutrients, and gases is critical to life (xylem and phloem for plants, circulatory systems for animals)
• Respiration: Plants (stomata) and animals (lungs/gills) optimize energy production in various environments
• Excretion: Plants (transpiration, vacuoles) and animals (kidneys) manage waste removal

Core Concepts

• Internal Structure: Plant tissues (parenchyma, collenchyma, sclerenchyma) and vascular tissues (xylem, phloem) are essential for transport. Animal organ systems (digestive, circulatory, nervous) interact to maintain homeostasis
• Nutrition: Plants synthesize their own food (autotrophs), while animals obtain it from other organisms (heterotrophs). This difference underscores ecosystem interdependence
• Transport: Plant transport systems (xylem, phloem) move water and nutrients; animal systems (circulatory) facilitate oxygen, nutrients, and waste transport
• Respiration: Plants use stomata; animals use lungs/gills for gas exchange. Adaptations optimize energy extraction
• Excretion: Plants get rid of excess water/waste; animals have specialized organs like kidneys for waste removal. This is crucial for homeostasis.
• Support and Movement: Plants use rigid cell walls for support; animals have internal/external skeletons for support and movement
• Reproduction: Plants and animals have diverse sexual and asexual reproductive strategies showcasing life cycle complexity
