- Angiosperms undergo syngenesis, in which the ovary is converted to fruit and the ovule is converted into the seeds. 
- Angiosperms are highly developed and vascular plants, which consist of xylem, phloem, and other specialized tissues. 
- The angiosperms have developed root and stem systems. Stem provides adherence and support, while roots help in the absorption of nutrients from the soil.
