2. What is the geographic distribution?Cosmopolitan; found on all continents except Antarctica
3. Why do plants make pseudanthia?Plants make pseudanthia to attract more pollinators. The big, bright look makes insects and birds notice them from far away, and the many tiny flowers inside help the plant make more seeds.
4. How do pseudanthia help pollinators?When a pollinator lands on a pseudanthium, it touches many florets at once, picking up pollen from many flowers and spreading it to others, so the plant can reproduce faster.
