  • Which statement describes how water is pulled up through the xylem to the leaves of the plant?
    Water is pulled up through the xylem to the leaves of the plant due to cohesion and adhesion. Cohesion allows water molecules to stick together, while adhesion helps them cling to the walls of the xylem, facilitating upward movement against gravity.
  • What type of bond is responsible for the cohesive property of water?
    C) Hydrogen bonds
  • Which property of water allows for it to move up a plant?
    The property of water that allows it to move up a plant is capillary action, which is facilitated by cohesion and adhesion.
  • What property of water makes it move upward from the roots of plants?
    The property of water that makes it move upward from the roots of plants is capillary action, driven by cohesion and adhesion.
  • Which property of water is due to the attraction between molecules of water?
    The property of water due to the attraction between molecules of water is cohesion.
  • To what type of surfaces are water molecules attracted?
    B) Polar surfaces
  • Which property or properties of life does water have?
    Water has properties essential for life, including cohesion, adhesion, high specific heat, and surface tension.
  • How does capillarity help sustain life?
    Capillarity helps sustain life by enabling water to move through plant xylem, allowing for the transport of nutrients and water from roots to leaves.
  • Which property helps trees move water from the soil to the top of the tree?
    The property that helps trees move water from the soil to the top of the tree is capillary action, which involves cohesion and adhesion.
  • How does water exhibit capillary action and what is its significance in plant biology?
    Water exhibits capillary action through cohesion and adhesion, allowing it to move against gravity in plant xylem, which is crucial for transporting water and nutrients.
  • What are the 4 properties of water?
    The four properties of water are cohesion, adhesion, high specific heat, and surface tension.
  • What three properties of water underpin all its effects on earth’s systems?
    The three properties of water that underpin its effects on Earth's systems are cohesion, adhesion, and high specific heat.
  • What properties of water allow water to move against gravity in the xylem of plants?
    Cohesion and adhesion allow water to move against gravity in the xylem of plants.
  • What property allows water molecules to stick to other water molecules as they move up the xylem?
    Cohesion allows water molecules to stick to other water molecules as they move up the xylem.
  • How is this property explained by the structure of water molecules and the bonds between them?
    Cohesion is explained by the structure of water molecules and the hydrogen bonds that form between them, allowing them to stick together.
  • What are the 5 properties of water?
    The five properties of water are cohesion, adhesion, high specific heat, surface tension, and solvent capabilities.
  • What term describes water molecules sticking to other water molecules?
    B) Cohesion
  • Which property of water allows it to move upward from the roots of a tree to its leaves?
    Capillary action, facilitated by cohesion and adhesion, allows water to move upward from the roots of a tree to its leaves.
  • Which property of water helps plants to transport water from their roots to their leaves?
    Capillary action, involving cohesion and adhesion, helps plants transport water from their roots to their leaves.
  • Which property of water allows a water strider to walk on water?
    Surface tension, resulting from cohesion and adhesion, allows a water strider to walk on water.
  • What is the function of cohesion?
    The function of cohesion is to allow water molecules to stick together, which is essential for processes like capillary action in plants.
  • What is cohesion in the context of water's properties?
    Cohesion is the ability of water molecules to stick to each other through hydrogen bonds.
  • How do hydrogen bonds contribute to water's cohesion?
    Hydrogen bonds form between water molecules, causing them to stick together and exhibit cohesion.
  • What is surface tension in water?
    Surface tension is the resistance of water's surface to being broken, caused by cohesion and adhesion.
  • Why can a paperclip float on water even though it is denser than water?
    A paperclip can float if placed carefully because water's surface tension prevents it from sinking.
  • What is the root meaning of 'co' in cohesion, and how does it relate to water?
    The root 'co' means 'together,' referring to water molecules sticking together through cohesion.
  • What type of bonds are responsible for water's cohesive property?
    Hydrogen bonds are responsible for water's cohesive property.
  • How does water's polarity contribute to its cohesive and adhesive properties?
    Water's polarity allows it to form hydrogen bonds, leading to both cohesion and adhesion.
  • How does surface tension benefit living organisms?
    Surface tension allows certain organisms to move or rest on water's surface without sinking.
  • What is an example of cohesion in everyday life?
    An example is water droplets forming beads on a surface due to water molecules sticking together.
  • What would happen to surface tension if water could not form hydrogen bonds?
    Surface tension would be greatly reduced or absent if water could not form hydrogen bonds.
  • What is the significance of surface tension in the natural world?
    Surface tension enables phenomena like insects walking on water and the formation of water droplets.
  • How does cohesion help plants transport water?
    Cohesion allows water molecules to stick together, enabling them to move as a column through plant vessels.
  • Why is it harder to break the surface of water compared to other liquids?
    It is harder because water's strong hydrogen bonds create high surface tension.
  • How do cohesion and adhesion differ in terms of molecular interactions?
    Cohesion involves water molecules bonding to each other, while adhesion involves water bonding to other substances.
  • How does surface tension relate to the density of objects placed on water?
    Surface tension can support objects denser than water if they do not break the surface.
  • How does the concept of cohesion explain the formation of water droplets?
    Cohesion causes water molecules to stick together, forming rounded droplets.
  • What would happen to surface tension if water molecules were non-polar?
    Surface tension would be much lower because hydrogen bonds could not form.
  • What is the biological importance of water's adhesive property?
    Adhesion helps water move through plant vessels and stick to biological surfaces.
  • How does water's surface tension compare to that of other liquids?
    Water has a higher surface tension than most other liquids due to its hydrogen bonding.
