    Study Notes

    Levels of Organization

    • The simplest and lowest level of organization is the cell.
    • Tissues are groups of similar cells that work together to perform a specific function.
    • An organ is a group of tissues that function together for a common purpose.
    • An organ system is a group of organs working together to perform a specific function.
    • An organism is a complete living being composed of organ systems.

    Types of Tissues

    • Epithelial Tissue: Covers surfaces and lines cavities.
      • Found in skin, mouth, lungs, blood vessels.
      • Functions: Protection, absorption, secretion, sensation.
    • Connective Tissue: Provides support and binds tissues together.
      • Examples: blood, bone, cartilage, ligaments, tendons.
      • Functions: Support, protection, binding.
    • Muscle Tissue: Contracts and relaxes for movement.
      • Types: Cardiac, striated, non-striated.
    • Nervous Tissue: Specialized cells called neurons transmit signals.
      • Components: Dendrites (carry messages towards the cell body), axon (carries messages away from the cell body).

    Plant Tissues

    • Meristematic Tissue: Found at growing points (tips of roots, stems, branches).
      • Function: Growth and multiplication.
    • Permanent Tissue: Made up of living or dead cells that have lost their ability to divide.
      • Simple Permanent Tissues:
        • Parenchyma: Living cells with thin cell walls and spaces between them, responsible for storage and support.
        • Collenchyma: Living cells with thick cell walls without spaces between them; provide support and flexibility.
        • Sclerenchyma: Dead cells with thick cell walls, provide strength and protection.
      • Complex Permanent Tissues:
        • Xylem: Transports water and dissolved minerals from roots.
        • Phloem: Transports food from leaves.

    Organ and Organ System

    • An organ is a group of tissues working together for a specific function. Examples: heart, lungs, kidneys, skin.
    • An organ system is a group of organs working together for a specific function. Examples: digestive system, respiratory system, excretory system.

    Xylem and Phloem

    • Xylem is similar to blood vessels in humans.
    • Both transport fluids throughout the organism.
    • Blood transports oxygen, nutrients, and waste products, while xylem transports water and minerals.

    Distinguishing Structures

    • Cell: The basic unit of life (e.g., neuron, egg, mesophyll cell).
    • Tissue: A group of similar cells working together (e.g., blood, bone, parenchyma).
    • Organ: A structure made of different tissues working together (e.g., leaf, eye, flower).
    • Organ System: A group of organs working together (e.g., skeleton, nervous system).
    • Organism: A complete living being (e.g., bacteria, mushroom, bear, human).
