Basal Angiosperms (many parts in each whorl) 2. Monocots (3/6 parts per whorl) 3. Eudicots (4/5 parts per whorl) --- class: center, middle, inverse

--- ### A few terms - All the petals = "corola" - All the sepals = "calyx" - Things that are in between petals and sepals = "tepals" - Radially symmetric = actinomorphic - Bilaterally symmetric = zygomorphic - Many flowers together = inflorescence
