    - Will not flower if dark period is interrupted by even a brief flash of light
    - Not affect if daytime period is broken by a brief exposure to darkness

5 True/False questions

  1. Fertile topsoil composition- rock particles of various sizes, living organisms, and humus. It is home to an astonishing number and variety of bacteria, algae, and other protists, fungi, and small animals such as earthworms, roundworms, and burrowing insects.


  2. Zoopharmacognosyzone of cell division, zone of elongation, and the zone of maturation.


  3. Dominant types of seed plantsfruit, wind, animals


  4. Angiosperm male/female gametophyteroot cells elongate, sometimes to more than ten times their original length; it is cell elongation that pushes the root tip farther into the soil; the cells lengthen, rather than expand equally in all directions, because of the circular arrangement of cellulose fibers in parallel bands in their cell walls. The cells elongate by taking up water and the cellulose fibers separate


  5. Dicot characteristicsA term traditionally used to refer to flowering plants that have two embryonic seed leaves, or cotyledons; branched veins; vascular bundles arranged in a ring; petals in multiples of 4 or 5; taproot.
