Slide 1
A fig hides its flowers inside
A fig encloses many small flowers rather than displaying them openly on a branch.

The structure commonly called a fig encloses many small flowers. Their hidden position changes the pollination problem: pollen must reach flowers inside, rather than flowers exposed on an open branch. An external photograph alone leaves the reproductive arrangement concealed.
Slide 2
Pollen must reach flowers in an internal cavity
Those flowers line a cavity connected to the outside by a small opening. Their enclosed position shapes the pollination problem.

The flowers line an internal cavity connected to the outside through a small opening. What appears to be a single fruit therefore encloses a flowering structure. This shared arrangement does not mean that every cultivated fig has the same pollination requirements.
Slide 3
A pollinating wasp can carry pollen through the opening
In the fig–wasp partnership, a female pollinating wasp carries pollen into the enclosed flowers. This links the plant’s reproduction with the insect’s reproductive life.

In the pollination mutualism, a female pollinating wasp carries pollen into the fig structure. The relationship connects plant reproduction with the insect's reproductive life. The benefits arise through an evolved biological association, not cooperation planned by either participant.
Slide 4
The partners do not always follow a one-to-one rule
The familiar rule of one pollinating wasp species for each fig species is too simple. Research reveals a more complicated relationship.

A common summary assigns one pollinating wasp species to each fig species. Research on New World fig wasps shows that host specificity is more complicated than that rule suggests. A memorable shorthand can introduce a relationship without accurately describing every case.
Slide 5
The partnership does not mean every edible fig contains a wasp
Fig–wasp mutualism, a relationship benefiting both partners, links insect reproduction with enclosed flowers. It does not establish that every edible fig contains a wasp.
More to Read
Fig-wasp relationships reveal how enclosed flowers and insect reproduction can become linked. They do not establish that every edible fig contains a wasp. Cultivated figs that develop without pollination are one reason the biology cannot be turned into a universal food claim.
