Angiosperms are commonly referred to as flowering plants, which have the highest division in Kingdom Plantae.
<h3>What are the characteristics of the Angiosperms?</h3>
- Angiosperms are flowering plants, which are characterized by the production of colorful flowers and fruits.
- 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.
Thus, angiosperms have the highest rank of division in the kingdom Plantae and bear several characteristic features like flowers, fruits, and roots.
