Study Notes
Plant Organ Systems
- Plants have two main organ systems: root system and shoot system
- Root system: responsible for absorbing water and nutrients from the soil, anchored to the soil, and stores food
- Shoot system: responsible for photosynthesis, supports the plant's growth, and produces flowers, fruits, and seeds
Animal Organ Systems
- Animals have 11 main organ systems: circulatory, respiratory, digestive, excretory, endocrine, nervous, musculoskeletal, integumentary, immune, reproductive, and urinary
- Each organ system has specific functions that work together to maintain homeostasis and ensure the survival of the organism
Chemical Control in Plants
- Plants use hormones to control growth and development
- Auxins: promote cell elongation and cell division, involved in apical dominance and root growth
- Gibberellins: promote stem growth and seed germination
- Cytokinins: promote cell division and differentiation
- Ethylene: regulates fruit ripening and senescence
Nervous Control in Animals
- Nervous system consists of central nervous system (CNS) and peripheral nervous system (PNS)
- CNS:composed of brain and spinal cord, integrates and processes information
- PNS: composed of sensory neurons and motor neurons, transmits information to and from the CNS
Chemical Control in Animals
- Endocrine system: uses hormones to regulate various bodily functions
- Hormones: chemical messengers produced by endocrine glands, transported through the bloodstream to reach target cells
- Examples of hormones: insulin, adrenaline, thyroxine, and growth hormone
- Functions of hormones: regulate metabolism, growth and development, and response to stimuli
