    Study Notes

    Transport of Materials in Animals

    • Animals and plants transport food, water, oxygen, and other important nutrients throughout their systems
    • Blood is used in humans to transport nutrients throughout the body
    • Harmful substances like carbon dioxide, sweat, urine are also transported through the bloodstream

    Platelets and Blood Clotting

    • Platelets are crucial for blood clotting
    • Without platelets, blood will not clot after an injury which could lead to excessive blood loss and even death

    Stomata in Plants

    • Stomata are tiny pores on plant leaves
    • Stomata regulate the exchange of gases like oxygen and carbon dioxide
    • Stomata help plants regulate water loss
