Symmetry and asymmetry in the angiosperms
Angiosperm : from Greek αγγειον + σπερμα (protected seed) Characteristics vascular plants having seeds producing flowers and fruits
How many species exist?? 720 20 000
Angiosperms MONOCOTS mostly herbaceous DICOTS herbaceous arboreal
monocots dicots Number of shape of the disposition of ribs of the structure of cots roots conductive vessels leaves the flowers

Microscopic Helianthus annuus Sunflower Pollens Ipomoea purpurea Purple morning glory Sidalcea Malviflora Mallow Oenothera fruticosa Evening primrose Lilium auratum Lily Ricinus communis Castor bean plant
What is it ?? Pollen grain of figwort (Ranunculus ficaria)
Ovary of Capsella
Conclusion When the flower is star-shaped it is actinomorph, i.e., it has a radial symmetry On the contrary, when the flower is butterfly-shaped it is zigomorph, i.e., it has a bilateral symmetry
