5 True/False questions
mycorrhiza → fungal infection
xylem → The nonliving portion of a plants vascular system that provides support and conveys xylem sap from the roots to the rest of the plant. Xylem is made up of vessel elements and/or tracheids, water-conducting cells. Primary xylem is derived from the procambium. Secondary xylem is derived from the vascular cambium in plants exhibiting secondary growth. DEAD CELLS MOVES WATER AND MINERALS UP FROM THE ROOTS.
Epiphytes → - a plant that grows on another plant, usually anchored to branches or trunks of living trees. Ex. Orchids. They absorb water and minerals from rain
Sporophyte → The multicellular haploid form in the life cycle of organisms undergoing alternation of generations; mitotically produces haploid gametes that unite and grow into the sporophyte generation
Function of micronutrients → cofactors, catalysts
