5 True/False questions
perennials → A plant that completes its life cycle in two years.
stomata → A modified leaf of a flowering plant. A whorl of sepals encloses and protects the flower bud before it opens.
root hair function → An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area.
mycorrhiza → plant roots + fungus= symbiotic relationship; mutually beneficial associations of plant roots and fungi, are common and may have helped the first plants adapt to land
Zone of cell division → includes the apical meristem and cells that derive from it; new root cells are produced in this region, including the cells of the root cap.
