Dimorphic

Definition

Dimorphic organisms exhibit two distinct forms within their life cycle, often adapted to different environments or functions. This feature is common in many species for survival and reproduction.

5 Must Know Facts For Your Next Test

1. 1. In Cnidarians, dimorphism typically involves a polyp stage and a medusa stage.
2. 2. Polyps are generally sessile (non-moving) and attached to substrates, whereas medusas are free-swimming.
3. 3. Different environmental conditions may trigger the transition between these forms.
4. 4. The polyp form reproduces asexually, while the medusa form typically reproduces sexually.
5. 5. Common examples of dimorphic Cnidarians include jellyfish, where the life cycle alternates between polyp and medusa stages.
