  1. Make a Flower Lab ASIM Biology Biology COS Objective 10

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

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

  4. 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 pollinators • a calyx -collective name for the sepals, which are the leaf-like structures at the flowers base to protect the developing bud • stamen(s) - the male portion of a flower • pistil(s) - the female portion of a flower

  5. A flower that possesses all 4 floral parts is said to be a complete flower. Additionally, flowers may be either perfect (containing both stamens and pistils) or imperfect (having either stamens or pistils).

  7. Monocots 1 cotyledon Floral parts in multiples of 3’s Parallel venation pattern in leaves Vascular bundles scattered in stem Fibrous root Examples: grasses, sedges, lilies, orchids and onions.

  9. Dicots • 2 cotyledons • Floral parts in multiples of 4’s or 5’s • Netted venation pattern in leaves • Vascular bundles arranged in a ring in stem • central taproot with lateral roots and root hairs • Dicots include broadleaf trees, shrubs, most flowers, and vegetables.

  11. For the next few slides, view the pictures and decide if the flower shown is a monocot or a dicot!
