    Study Notes

    Cells and Tissues Overview

    • Prokaryotic cells lack a nucleus; eukaryotic cells possess one.
    • Mitochondria serve as the energy-producing organelles in both plant and animal cells.
    • Ribosomes are essential for protein production within cells.
    • Fimbriae are bristle-like appendages that allow prokaryotes to adhere to surfaces.
    • Plasmids are structures commonly found in bacteria and can carry genetic information.

    Learning Competencies and Objectives

    • Classify different cell types in plant and animal tissues.
    • Differentiate between parenchyma, sclerenchyma, and collenchyma cells in plants.
    • Describe the functions of dermal, ground, and vascular tissues in plants.
    • Identify various animal cell types, including blood, nerve, and bone cells.
    • Explain the functions of the four major animal tissue types.

    Plant Tissues and Histology

    • Histology is the study of cells and tissues.
    • Plant tissue is divided into meristematic and permanent types.
    • Meristematic tissue comprises young, immature cells that continuously divide, contributing to plant growth in length and girth.
    • Permanent tissue arises from meristems and comprises mature, non-dividing cells.

    Types of Plant Meristems

    • Primordial Meristem: Earliest tissue, arises from embryonic origin.
    • Primary Meristem: Develops into three types:
      • Protoderm: Forms the epidermis.
      • Procambium: Develops into primary xylem and phloem.
      • Ground Meristem: Forms cortex and pith.
    • Secondary Meristem: Lateral meristems that include:
      • Vascular cambium: Produces secondary xylem and phloem.
      • Cork cambium: Produces periderm, replacing the epidermis.

    Types of Permanent Plant Tissues

    • Dermal Tissue: Protective outer covering of plants, includes:
      • Epidermis: A single layer of parenchymatous cells containing stomata and cuticle.
      • Periderm: Multilayered, replaces epidermis during secondary growth.
    • Ground Tissue: Fills soft parts of plants, involved in photosynthesis and storage.
    • Vascular Tissue: Transport system for water and nutrients throughout the plant.

    Types of Ground Tissue

    • Parenchyma: Thin-walled living cells, involved in photosynthesis and storage.
    • Collenchyma: Elongated cells with thicker walls, provide flexible support.
    • Sclerenchyma: Dead cells with thick, rigid walls, provide mechanical support.

    Vascular Tissue Components

    • Xylem: Composed of non-living cells; transports water and minerals from roots to leaves.
    • Phloem: Complex tissue responsible for nutrient transport throughout the plant.

    Functions of Meristematic Tissue

    • Differentiate into specialized structures, responsible for growth and development.
    • Help in tissue formation, leading to plant structure maturity.

    Summary of Major Plant Tissue Functions

    • Dermal tissue: Provides a protective layer for plants.
    • Ground tissue: Fulfills storage, photosynthesis, and support needs.
    • Vascular tissue: Transports water and nutrients across plant systems.

    Key Terms

    • Meristematic Tissue: Undifferentiated cells for growth.
    • Permanent Tissue: Mature cells that have established specific functions.
    • Xylem and Phloem: Primary transport tissues in vascular plants.
