    Study Notes

    Tissue Overview

    • Tissues are groups of similar cells working together for a specific function.
    • Structural organization in animals is more specialized compared to plants, reflecting different modes of life.
    • Plant tissues adapt to a sedentary existence, while animal tissues are adapted for active locomotion.

    Types of Tissues

    • Tissues are categorized into two main types: plant tissues and animal tissues.

    Plant Tissues

    • Meristematic Tissue:

      • Composed of actively dividing cells; dense cytoplasm, thin cell walls, and prominent nuclei.
      • Lacks vacuoles for efficient growth in specific regions.
      • Includes apical meristem (found at the tips of roots and shoots) and intercalary meristem (located near nodes).

    • Permanent Tissue:

      • Formed from meristematic tissue after differentiation; cells lose the ability to divide.
      • Classified as simple and complex tissues.
      • Simple Permanent Tissue:
        • Parenchyma is the most common type; functions include food storage, with loosely arranged cells and intercellular spaces.
      • Complex Tissue:
        • Comprises multiple cell types that coordinate to perform functions.
        • Includes Xylem (transports water and minerals) and Phloem (transports food).

    Animal Tissues

    • Classified into four main types: epithelial, connective, muscular, and nervous tissue.

    • Epithelial Tissue:

      • Composed of closely packed cells; classified based on shape (squamous, cuboidal, columnar) and specialization (ciliated, glandular).

    • Connective Tissue:

      • Provides support and structure; includes areolar connective tissue (fills spaces, supports organs) and adipose tissue (stores fat, insulates body).
      • Blood is considered a connective tissue, transporting oxygen, nutrients, and waste.

    • Muscular Tissue:

      • Comprised of elongated muscle fibers responsible for movement.
      • Contains contractile proteins that enable contraction.
      • Includes skeletal muscle (attached to bones), cardiac muscle (found in the heart), and smooth muscle (involuntary actions).

    • Nervous Tissue:

      • Composed of neurons (nerve cells) and supporting cells (glial cells).
      • Neurons have unique structures: a long axon and multiple dendrites for signal transmission.

    Summary of Key Functions

    • Tissues enable specialization and efficiency in multicellular organisms.
    • Plant tissues contribute to growth, support, and transport, while animal tissues facilitate movement, support, and communication.
