- Draw a generalized pine tree life cycle and identify the following structures: male and female gametophytes, pollen grain, integuments, archegonium, egg, embryo, and sporophyte.Review the life cycles of the three major plant groups (bryophyte or non-vascular plants, seedless vascular plants, and seed plants). Be able to identify the gametophyte and sporophyte generations in each plant group. Make one graph that shows patterns of changes in the following characteristics, as the different plant groups (bryophytes or non-vascular plants, seedless vascular plants, and seed plants) appeared or evolved on land through time. 1) size of the gametophyte generation 2) size of the sporophyte generation 3) biomass (amount of organic material) stored in the sporophyte 4) degree of dependence on water for fertilization Make sure the y- and x- axes of the graph, labels and title are included and correctly applied.The kingdom Plantae constitutes large and varied groups of organisms. There are more than 300,000 species of identified and cataloged plants. Using the geologic record, discuss and explain when and how plants colonized the land. Include the adaptations that enabled them to survive on land amid the harsh environmental conditions.
