Three major functions of leaf.​

AdaptionPurpose

Large surface areaTo absorb more light

ThinShort distance for carbon dioxide to diffuse into leaf cells

ChlorophyllAbsorbs sunlight to transfer energy into chemicals

Network of veinsTo support the leaf and transport water and sugars

Explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
