Plants

• Three different plant Organs: Root, Stem, and Leaf
• Vascular bundles transport food, water and minerals throughout the plant
• Xylem is made up of two transport tissues
• two transport tissues

  • Xylem
  • Phloem
• Xylem have a unidirectional flow while Phloem have a multidirectional flow
• the main function of the roots are to absorb water and minerals from the soil
• roots keep the plant anchored
• roots contain root hair cells
• Absorbtion: the water and minerals pass through the cell membrane of the root hair cells
• the concentration of solutes in the root hair cells is higher than in the soil
• water is taken up by osmosis
• minerals are taken up by active transport
• active transport requires energy
• water taken by root hair cells are moved to the xylem either by osmosis or by diffusion
