  1. Stroma
    Fluid in between grana, where carbohydrate-formation reactions occur in the chloroplasts of plant cells photosynthesizing.
  2. Thylakoid
    • Site of the light-dependent reactions of photosynthesis.
    • Form stacks of disks referred to as grana.
    • Thylakoid membrane surrounding a thylakoid lumen.
  3. Grana
    Stacks of thylakoids.
  4. Leucoplasts
    • A category of plastid.
    • They are non-pigmented.
    • They are white and colorless, so they are located in roots and non-photosynthetic tissues.
    • Specialized for bulk storage of starch and lipids and are then known as amyloplasts and elaioplasts.
  5. Parenchyma
    The ground tissue ofnonwoody structures.
  6. Epicotyl
    • Stemlike shoot above the cotyledons attached at the hypocotyl.
    • In most plants the epicotyl will eventually develop into the leaves of the plant.
    • Includes plumules.
  7. Plumule
    • The rudimentary terminal bud of a plant embryo situated at the end of the epicotyl, consisting of the epicotyl and often of immature leaves.
    • Forms the shoot of the plant.
  8. Radicle
    The embryonic root of the plant, and grows downward in the soil.
  9. Hypocotyl
    Stem of a germinating seedling, found below the cotyledons and above the radicle.
  10. Meristem
    The undifferentiated plant tissue from which new cells are formed, as that at the tip of a stem or root.
  11. Apical meristem
    • A meristem at the tip of a plant shoot or root that causes the shoot or root to increase in length.
    •  
  12. Lateral meristem
    • A meristem in vascular plants, such as the cambium, in which secondary growth occurs.
    •
