Compare their characteristics
| Trait | Thale Cress | Acropora millepora |
|---|---|---|
| Physical traits | Small rosette leaves, slender flowering stems and white, four-petalled flowers characterize the plant. Long, narrow fruits contain many small seeds. | Colonies form branching structures covered by small skeletal cups that house polyps. Colony color alone is insufficient for secure species identification. |
| Habitat and range | Open, disturbed ground and other relatively sparse vegetation provide growing sites. Laboratory accessions represent only part of natural diversity. | Shallow, well-lit marine reef environments support the coral and its photosynthetic partners. |
| Diet and nutrition | Leaves manufacture sugars by photosynthesis. Stored seed reserves support the seedling before its leaves become established. | Polyps capture small suspended food, while algal symbionts contribute photosynthetic products. |
| Behavior and activity | Flowering responds to inherited differences and environmental conditions, including temperature history and day length. | Tentacles and mucus help the colony interact with surrounding seawater. Recognition mechanisms influence responses to microbes. |
| Reproduction and life cycle | Plants usually self-pollinate. Depending on genotype and conditions, a laboratory generation can be completed within weeks; wild seasonal cycles differ. | Colonies grow by producing additional polyps. Sexual reproduction can release gametes that develop into settling larvae. |
| Geographic distribution | Native populations occur in Africa, Asia and Europe; the species is naturalized in other regions. | The species occurs in the Indo-Pacific reef region. Species-level locality records should accompany detailed range mapping. |
| Ecological role | This small annual exploits gaps where competition is limited. Seed dormancy helps bridge unsuitable periods. | Skeletal growth contributes reef structure and habitat. Symbiotic interactions are central to energy supply and colony health. |
| Distinctive adaptations | A short generation time, small size and abundant seed production facilitate both colonization and genetic research. | A colonial body and partnerships with photosynthetic cells support growth in well-lit reef environments. |
| Conservation | Research stocks are not substitutes for conserving natural genetic diversity. No formal threat category is inferred from laboratory abundance. | Thermal stress, bleaching and degradation of reef habitat are concerns. A source on molecular recognition does not establish a current Red List category. |
