Document Summary

Sieve cells in ferns + non floweing vas plants primitive, water conducting cells lack sieve plates, overlap and don"t form tubes lack nucleas @ maturity have albuminbus cell ( nucleated cell) funcs like companion cells. Tubers: run above the soil surface, underground ogrow below ground ohave long to short internodes ograss, ferns, have roots and leaves at each node, strawberry, swollen ends of rhizomes, store food, potato. More xylem produced=each year"s growth produce 2 xylem ( to inside) + phloem ( to outside) in dic+ conifer stem= growth begins when vas. Cambium forms a discontinuous series of section= become a closed ring pericycle cells=part of vascular cambium. Chlorophyll b blue green pigment directly involved in light rxns absorbs blue + red and transmits green yellow green transfers absorbed light energy to chlorophyll a but doesn"t take part in light rxns accessory pigment absorbs blue + red and transmits green.
