Plant cell organisation

• Plant Cell Organisation


  • Plants keep their specialised cells neat and tidy
• Plant organs


  Made of tissues, work together to perform various tasks for the plant to survive and grow
• Examples of plant tissues

  • Epidermal tissue
  • Palisade mesophyll tissue
  • Spongy mesophyll tissue
  • Xylem and phloem
  • Meristem tissue
• Leaf


  An organ made up of several types of tissue
• Tissues found in a leaf

  • Epidermal tissue
  • Mesophyll tissue
  • Xylem
  • Phloem
• Epidermal tissue


  • Covered with a waxy cuticle to reduce water loss
  • Transparent to allow light to pass through to the palisade layer
• Palisade layer


  • Has lots of chloroplasts to carry out photosynthesis
• Xylem and phloem


  • Form a network of vascular bundles to deliver water, nutrients and transport glucose
• Leaf structure


  • Stomata allow CO2 to diffuse into the leaf
  • Air spaces in spongy mesophyll increase gas diffusion rate
