The cuticle is a waxy covering that covers

Nonwoody above ground plant parts

Describe how certain characteristics of flowers promote pollination.

Colored petals, strong scents,some are adapted for self pollination, wind pollination of grasses.

Trace the development of aspirin.

Solutions were made by soaking the bark of willow trees to get salicin which gave rise to acetylsalicylic acid or aspirin.
