Description
Lily anther. Light micrograph of a cross-section through a lily flower anther (Lilium sp.), showing four anther sacs (curled structures). The anther sacs, or pollen sacs, are filled with developing pollen grains, or male sex cells (orange). The inside of the anther wall produces a nutrient fluid to nourish the pollen mother cells, from which these grains are derived. When the pollen grains are mature, the anther walls split to release them. Magnification: x44 when printed 10 centimetres wide.
