Plant Structure and Functions

Answer the questions below while watching the video. Plants produce oxygen. true false What are the two major plant categories? Water is absorbed through the roots of a plant and travel through the phloem. true false What are two functions of the roots of a plant? Sugar (glucose) is produced during photosynthesis. true false Phloem carries sugars throughout the plant. true false When water is being carried up a tree through xylem, what force is it fighting against? Both plants and humans go through photosynthesis. true false What are the three major reactants photosynthesis needs in order to work? light, oxygen, water water, carbon dioxide, oxygen light, carbon dioxide, water carbon dioxide, water, sugar Both plant cells and animal cells have chloroplasts. true false Gases (carbon dioxide and oxygen) exchange occurs in what structure of the plant? roots stem leaves flowers Plants have _ in order to help them survive in an environment. bugs adaptations xylem phloem Answer the questions below during the powerpoint. What are the three main structure of a plant? flower, root, leaves leaves, stem, xylem root, stem, leaves xylem, phloem, photosynthesis What are other parts of a plant besides the leaves, stems, and roots? Roots •Absorb and transports water and nutrients•Anchor plants in the ground•Hold soil in place and prevent erosion•Storage of sugars made in photosynthesis What are some examples of taproots? What are some examples of fibrous roots? Stems •Support for the plant body•Produces leaves, branches, and flowers•Carries nutrients throughout the plant•Most stems grow upwards, but some grow sideways Why would a stem grow sideways? xylem transports water up the plant phloem transports sugar (glucose) throughout the plant What would happen if the plant's xylem tissue was damaged? food could not get to the leaves food could not get to the roots water could not get to the leaves water could not get to the roots Leaves •Where photosynthesis occurs•Many different shapes, sizes, and arrangements•Transpiration •Loss of water through leaves •Replaced by water absorbed by roots Why are some leaves different from others?
