    Study Notes

    Plant Structure and Function

    • Vascular cambium is located between xylem and phloem and is responsible for increasing the plant's height.
    • Apical meristem is responsible for increasing the length of the plant as it grows.
    • Cork cambium acts as a protective layer, pushing old and non-functioning xylem to the outermost layers.

    Plant Tissue

    • Dermal tissue includes guard cells and root hair.
    • Ground tissue in plants includes parenchyma, collenchyma, and sclerenchyma.

    Plant Transport

    • Transpiration involves the loss of water vapor through stomata on the leaves.
    • Water moves upward in the xylem through a passive process of transpiration.
    • Glucose moves downward in the phloem through a passive process called translocation.

    Animal Circulatory System

    • The circulatory system is used to transport nutrients and gases through the body of all animals.
    • The right side of the heart collects oxygen-rich blood and pumps it to the tissues through the aorta.
    • Pulmonary circulation involves the flow of blood away from the heart through the lungs, where oxygenation occurs.
    • Coronary circulation supplies oxygen to the tissues in the body.

    Heart Function

    • The division of the heart into two sides prevents oxygen-rich blood from mixing with oxygen-poor blood.
    • Oxygenation of the blood occurs in the lungs during pulmonary circulation.
    • O2-poor blood returns to the heart after circulating throughout the body.
    • In capillary beds, oxygen diffuses into the tissues as CO2 diffuses into the bloodstream.
