Study Notes

Plant and Animal Organ Systems

  • Organ systems in animals and plants consist of a hierarchy of structures, from atoms to organisms.
  • The fundamental building block in both plants and animals is a cell.
  • Specialized cells perform specific functions within complex organisms.
  • A tissue is a group of similar specialized cells working together.
  • An organ combines different kinds of tissues.
  • An organ system is a group of organs working together to perform a major function.
  • An organism is a complete living thing, made up of all these structures.

Plant Tissues/Specialized Cells

  • Parenchyma cells are the most abundant and least differentiated.
  • Collenchyma provides support.
  • Sclerenchyma cells have tough walls that don't undergo mitosis.
  • Dermal tissue forms the outer layer.
  • Vascular tissue transports water and nutrients (xylem and phloem).

Plant Growth/Meristem

  • Meristems are embryonic stem cells that create other cells.
  • These are located on the tips of developing parts.

Plant Gas Exchange

  • Stomata are guarded by guard cells, promoting CO2 intake and water and O2 exchange.
  • They are necessary for the Calvin Cycle.

Plant Energy Production/Mineral Transport

  • Photosynthesis in leaves produces sugars.
  • Sugars are transported throughout the plant.
  • Roots absorb water and minerals.
  • Symbiotic relationships with fungi—like mycorrhizae—increase water absorption.
  • Rhizobium converts nitrogen into usable forms.

Plant Hormones

  • Plants have seven main hormones: auxin, cytokinins, gibberellins, brassinosteroids, oligosaccharins, ethylene, and abscisic acid.
  • These hormones control various processes including cell growth, differentiation, flowering, and fruit ripening.

Plant Reproduction/Pollination

  • Pollination is the transfer of pollen from the anther to the stigma.
  • Double fertilization ensures endosperm development.

Plant Evolution

  • Plant evolution illustrates the development from mosses to flowering plants, showing progression in features like seeds and vascular tissue.

Animal Structures/Organ Systems

  • Animals have organ systems like the digestive, respiratory, nervous, circulatory, and excretory systems.
  • The specific structures and functions vary between animals.

Animal Digestive System

  • Structures include the mouth, esophagus, stomach, small intestine, large intestine, gallbladder, liver, pancreas, rectum, and anus.
  • Function of the system is to process food for absorption and excretion, supplying glucose for cellular respiration.

Animal Respiratory System

  • Structures include the trachea, bronchi, lungs, diaphragm (in mammals), and gills (in fish).
  • Function includes gaseous exchange (oxygen intake and carbon dioxide release), vital for survival.

Animal Nervous System

  • Structures include neurons, axons, dendrites, and synapses.
  • Functions include controlling the body, communicating within parts, regulating processes, and coordinating with other systems.

Animal Circulatory System

  • The system includes the heart, blood vessels, and blood.
  • Function is transporting blood and oxygen throughout the body.
  • Adaptations like a four-chambered heart are designed to separate oxygenated and deoxygenated blood.

Animal Excretory System

  • Structures include kidneys, glomeruli, nephrons, Bowman's capsule, loop of Henle, and collecting ducts.
  • Function to filter blood, regulate water balance, and excrete nitrogenous waste.

Animal Muscular System

  • Muscle cells contain actin and myosin protein filaments.
  • Sarcomeres are the structural units of myofibrils.
  • Tropomyosin and troponin are regulatory proteins.
  • The system enables movement through muscle contraction.

Animal Immune System

  • Lymph system and leukocytes (white blood cells) protect against foreign substances and infection.
  • Lymphocytes, macrophages, B cells, and T cells play distinct roles.
  • The system's function is defending the body from pathogens.

Animal Reproductive System

  • Structures include testicles (men) or ovaries (women), penis/vagina, various ducts, glands, and reproductive organs.
  • Function to create offspring and sex cells.
