Caption: Light micrograph showing the reproductive structures of the green alga Vaucheria sp. The outgrowth in the centre is a young antheridium (male sex organ), either side of which are round oogonia (female sex organs) each of which contains an egg. The eggs are fertilised by antherozoids from the antheridium, and form zygotes. A zygote secretes a thick wall and remains dormant for some months before it germinates to give rise to a new algal filament. Magnification: x140 at 35mm size.
