    Study Notes

    Plant Tissue

    • Plant growth occurs only in specific regions known as meristematic tissue.
    • Meristematic tissue is responsible for cell division and growth.
    • There are three types of meristematic tissue: apical, lateral, and intercalary.
    • Apical meristem is found at the tips of stems and roots, increasing the length of the plant.
    • Lateral meristem is found in the vascular cambium and cork cambium, increasing the width of the plant.
    • Intercalary meristem is found at the base of leaves and internodes, increasing the length of internodes.
    • Permanent tissues are formed from meristematic tissue when cells lose their ability to divide.
    • Permanent tissues are classified based on cell structure and function: parenchyma, collenchyma, sclerenchyma, and complex permanent tissue.
    • Parenchyma tissue is living, loosely packed cells with thin walls and large intercellular spaces. It provides support and storage, and can carry out photosynthesis (chloroplasts) or aeration (aerenchyma).
    • Collenchyma tissue is living, elongated cells with thickened cell walls, mainly made of cellulose and pectin. They provide mechanical support and flexibility to stems and leaves.
    • Sclerenchyma tissue is composed of long, dead cells with thick, lignified cell walls. They provide strength and support to the plant body.
    • Complex permanent tissue includes xylem and phloem, which are responsible for transporting water, minerals, and nutrients throughout the plant.
    • Xylem transports water and minerals unidirectionally from roots to leaves. It consists of tracheids, vessels, fibers, and xylem parenchyma.
    • Phloem transports food and other soluble substances bidirectionally throughout the plant. It consists of sieve tubes, sieve cells, companion cells, phloem fibers, and phloem parenchyma.
    • Epidermis is the outermost protective layer of the plant body, preventing water loss, injury, and pathogen invasion.
    • Epidermis is covered with a waxy layer called cuticle.
    • Stomata are small pores on the epidermis that facilitate gas exchange.
    • Cork is a protective layer that replaces the epidermis in older stems and roots.

    Animal Tissue

    • Animal tissues are specialized groups of cells that perform specific functions. There are four major types: epithelial, connective, muscular, and nervous.
    • Epithelial tissue forms linings and coverings of internal and external surfaces.
    • Blood is a connective tissue with plasma, red blood cells, white blood cells, and platelets. It transports oxygen, nutrients, carbon dioxide, waste products, hormones, and cells throughout the body.
    • Connective tissue provides support, binds together tissues, and protects organs.
    • Bone is a type of connective tissue that provides support, protection, and aids in movement, with a matrix composed of calcium, phosphorus, and other compounds.
    • Ligaments are strong connective tissues that connect bones to each other providing strength and flexibility.
    • Tendons connect muscles to bones, allowing for muscle movement.
    • Cartilage is a type of connective tissue found in joints, ears, and nose, providing cushioning and support.
    • Areolar connective tissue is found beneath the skin and around organs, providing support and cushioning.
    • Adipose tissue stores fat and functions as insulation for the body.
    • Muscular tissue is responsible for movement, with three major types: skeletal, smooth, and cardiac.
    • Skeletal muscle is voluntary, striated, elongated, cylindrical, and multinucleated. It attaches to bones and allows for voluntary movement.
    • Smooth muscle is involuntary, unstriated, spindle-shaped, and uninucleated. It is found in the walls of blood vessels, digestive tract, and other internal organs.
    • Cardiac muscle is involuntary, striated, branched, and uninucleated. It is found only in the heart and responsible for pumping blood.
    • Nervous tissue is responsible for communication and coordination, composed of neurons.
    • Neurons consist of a cell body, dendrites, and an axon. They transmit nerve impulses from one part of the body to another.
