• ovary (the fruit)


  serves as the protective layer enveloping seeds
• Gymnosperms have unenclosed seeds.
• Gymnosperm can be translated as naked seeds.
• Classification: Cycadophyta Ginkgophyta Coniferophyta or Pinophyta and Gnetophyta
• Conifer Shoot System Parts: Acicular, Fascicle, Terminal bud, Lateral bud
• Acicular leaves – long needle-like leaves
• Fascicle -bundle of leaves and may be 1 leaf (monofoliar) or 2 to 5

  (multifoliar)
• Terminal bud -serves as the primary growing point of plants found at the tips of stems
• Lateral buds - growing point found near the leaves and may become

  vegetative shoots such as stems or leaves or reproductive

  structures such as flowers
• Vascular bundle (or stele) is composed of the pericycle, xylem, and phloem.
• Xylem- transports water from roots to shoots
• Phloem- transports photosynthates from shoots down to roots
• Pericycle - a thin layer of parenchyma or sclerenchyma cells at the outermost part of a stele
• Species: Cycads, Ginkgo, Pinus, and Gnetum
