Plants

this is a (not done) mindmap of plants and their various events inside them

  • Plants
    • Starch
      • only found in green parts of plants (variegated leaves do not contain them)
      • "testing for starch:   1:take a leaf from a plant  2: kill in boiling water to get rid of the cuticle on the leaf which stops iodine getting through 3: remove the leaves colour with ethanol  4:wash the leaf with cold water 5: add iodine solution to the leaf (TIPS: put the leaf on a white surface to show the colour)"
    • photosynthesis
      • only found in green parts of plants (variegated leaves do not contain them)
      • glucose
      • carbon dioxide + water --> glucose + oxygen
      • 6CO2 + 6H2O --> C6H126O + 6O2
    • The structure of leaves
      • (spongy) mesophyll
        • palisade cells
          • (where most of the chloroplasts are)
        • Spongy cells
        • Vein
          • Xylem
            • Transports; water and mineral ions
          • Phloem
            • Transports: products of photosynthesis, such as sugars
      • Lower epidermis
        • Guard cells
          • contains pores called stomata (single one: stoma)
      • the upper epidermis: the cuticle
      • outer layer of cells
        • the upper epidermis: the cuticle
        • Lower epidermis
          • Guard cells
            • contains pores called stomata (single one: stoma)
