    Study Notes

    Muscle Tissues

    • Smooth muscles are found in the iris of the eye, ureters, and bronchi
    • Smooth muscle cells are long with pointed ends, and are uninucleate
    • Smooth muscles are also called unstriated muscles
    • Cardiac muscles are found in the heart
    • Cardiac muscles show rhythmic contraction and relaxation throughout life
    • Cardiac muscles are involuntary.
    • Cardiac muscles are cylindrical, branched, and uninucleate

    Nervous Tissue

    • Nervous tissues are specialized to respond to stimuli and transmit the stimulus rapidly
    • All cells have the ability to respond to stimuli

    Plant Tissues

    • Epidermis is the outermost layer of cells in plants
    • In plants living in dry habitats, the epidermis is made of a single layer of cells
    • Cork cells are dead, compactly arranged, and lack intercellular spaces
    • Cork cells have suberin in their walls making them impervious to gases and water.
    • Phloem cells are living cells except for phloem fibers
    • Xylem consists of tracheids, vessels, xylem parenchyma, and xylem fibers.
    • Xylem cells have thick walls, and many are dead.
    • Tracheids and vessels are tubular structures that transport water and minerals vertically
    • Xylem parenchyma stores food and helps in the sideways conduction of water.
    • Phloem is made up of sieve tubes, companion cells, phloem fibers, and phloem parenchyma
    • Sieve tubes are tubular cells with perforated walls
    • Phloem unlike xylem allows materials to move in both directions

    Meristematic Tissue

    • Apical meristem is located at the growing tips of stems and roots
    • Apical meristem increases the length of stems and roots
    • Lateral meristem increases the girth of stems and roots
    • The intercalary meristem is located at the base of leaves or internodes
    • Meristematic tissues have cells with dense cytoplasm, thin cellulose walls, and prominent nuclei
    • Meristematic tissues lack vacuoles

    Permanent Tissue

    • Permanent tissues lose the ability to divide and take up a specific role.
    • Permanent tissues are formed from meristematic tissues

    Simple Permanent Tissue

    • Simple permanent tissues are made of one type of cell
    • Simple permanent tissues coordinate to perform a common function

    Complex Permanent Tissue

    • Complex tissues are made up of more than one type of cell.
    • Xylem and phloem are examples of complex tissues
    • Xylem and Phloem constitute a vascular bundle
    • Vascular tissue is a distinctive feature of complex plants.
    • Xylem transports water and minerals
    • Phloem transports food from leaves to other parts of the plant

    Tissues in Animals and Plants

    • Animals and plants have different structures and perform different functions
    • Plant and animals have different modes of life
    • Animals and plants have different feeding methods
    • The structural organization of organs and organ systems is more specialized in animals than in plants
