What are the roles of copi vesicles

Q1. 1) How does a new Golgi cisterna form in the cis side from COPII vesicles?
2) What happens to trans-Golgi network as buIDing secretory/clathrin coated vesicles consume its membrane?
3) What are the roles of COPI vesicles for transporting proteins between Golgi cisternae?
Q2. What are the morphological features (leaves, twigs, wood, flowers, pollen grains, and fruits) of the superorders in the Cronquist classification system (Magnolianae, Hamamelidanae, Rosanae, Dillenianae, Asteranae)?
