I.6 Examination of the Surface of Pollen Grains

Aim

To observe the external form and surface patterning of pollen grains.

Specimen & Apparatus

  • Fresh pollen (e.g. lily, daisy, or dandelion)
  • Slide and coverslip
  • Water
  • Compound microscope

Method

  1. Transfer a small quantity of pollen to a slide.
  2. Add a drop of water to disperse the grains.
  3. Apply a coverslip gently.
  4. Examine under low power to locate grains.
  5. Increase magnification to observe surface detail.

Observations to Make

  • Shape and size of pollen grains.
  • Surface texture or sculpturing.
  • Presence of apertures or pores.
  • Variation between grains (if present).
