  • IntroductionIn this lab, we will be studying angiosperms. Angiosperms are vascular plants (have water and nutrient conducting structures) that produce flowers, which contain the plants reproductive organs.

  • Within the flower, seeds will be produced.In angiosperms, seeds are enclosed in a structure called the ovary, which will mature into a fruit.

  • There are four major floral parts:a corolla -the collective name for the petals, which are above the sepals and are usually brightly colored and sometimes scented to attract pollinatorsa calyx -collective name for the sepals, which are the leaf-like structures at the flowers base to protect the developing budstamen(s) - the male portion of a flowerpistil(s) - the female portion of a flower
