(Some may use sunlight or water) 3. The accessory pigments are used to produce certain nutrients needed for cell wall structure / support of the organism. 4. Environmentally, the plant can spread much faster and farther with two generation (for ex. Pollen traveling to another flower). This same example can be used to describe how it can help with evolution or the reproductive cycle, because pollen with certain genetic information can land on a flower with different genetic information to produce a seed. 5. The dominant generation is the generation in which the organism spends most its time. 6. A haploid number of chromosomes is an N number of chromosomes, meaning one set. 7. A diploid number of chromosomes is a 2N number of chromosomes, meaning two

Unformatted text preview: sets. 8. Since the haploid set of chromosomes has half the chance of having much genetic variety (only one set of chromosomes versus two), it most likely decreases the general variability of the organism that is dominant in the gametophyte generation. 9. They are considered more advance because in the event there is a lack of water the plant can still reproduce through the air. 10. The root-vascular system enables the plant to carry nutrients from the bottom of the plant (in the soil) to the top of the plant and then release toxins into the soil as well. 11. The plants needed to develop cuticles (to cover the stomata) on the leaves and outer surface to prevent water loss and ground tissue to carry nutrients and water. 12. The plants needed to develop vascular tissue (for support) to grow both tall and wide....
