Tissues and Organs in Plants

• Plant tissues:

  • Epidermal
  • Palisade
  • Spongy
  • Xylem
  • Phloem
• Epidermal Tissue: Covers the surface of the leaf and often waxy for it to be waterproof
• Palisade Mesophyll= The surface layer of the leaf containing a lot of chloroplast for photosynthesis
• Spongy mesophyll = Has lots of air spaces and chloroplast for photosynthesis and so that gases can diffuse easily into/out of the cells.
• Xylem tissue = Transports water from roots up through stem to leaves, also transports minerals from soil to plant
• Phloem tissue = Transports sugars made by plants during photosynthesis around the plant
• Main type of plant organs:

  • Roots
  • Leaves
  • Stems
