Document Summary
Formation of phragmatoplasts genetic evidence comparisons of nuclear and chloroplast genes point to close relationship between charophytes and land plants the move to land durable polymer sporopollenin found in charophyceans and land plants prevents spores for drying out great opportunity for adaptive radiation sunlight unfiltered by water and plankton abundance of co2 nutrient rich soil few herbivores and pathogens. Thin flexible primary cell walls; alive at maturity; carry out most metabolism w/in plant: collenchyma (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) Lateral roots (figure 35. 15) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) Areas in the periderm where gas exchange with the outside air can occur (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) Uptake of sucrose (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) (cid:222) Pollen: the male gametophyte (cid:222) (cid:222) (cid:222) (cid:222) (cid:222: each microsporangium contains diploid microsporocytes (microspore mother cells, microsporocytes divide by meiosis to produce microspores.
