Natural landscaping
Natural landscapingReduces time and expense of mowing Reduces need for watering Advantages of natural landscaping: Reduces need for fertilizers and pesticides Provides habitat for wildlife Native plants are those naturally growing in the region; well-adapted to local climate Natural landscaping allows plants to grow and reproduce with minimal interference Natural landscaping involves the use of native plants to approximate a natural community |

Plant pests: Weeds
Plant pests: WeedsWeeds = any plant growing in an unwanted location Weeds reduce yields of horticultural crops through: Competition for nutrients, water, light Allelopathy = chemical competition Serving as hosts for insect pests Weeds |

Mitosis
MitosisHow are new organisms produced? Reproduction Two general steps: Growth and development of zygote Produce more cells (growth) Specialize cells and organize into tissues and organs (development) Produce sex cells (gametes) Fertilization Question 2: How do you make a new chicken, or a new tree? |

Plant reproductive modes
Plant reproductive modesHow are new organisms produced? Seed plants Heterosporous (different types of spores) Reproduction less dependent on water Sporophyte dominant; gametophyte reduced and dependent Evolution of seed, an embryo protected by extra layer of sporophyte tissue (seed coat) Protects embryo from desiccation Dormant part of life cycle; able to survive until favorable conditions appear Enhances dispersal Sperm in pollen travels to egg through pollen tube, eliminating need for external water during fertilization Comparison of reproductive modes of plants: |

Plant pests
Plant pestsNoninfectious plant diseases Plant problems caused by unfavorable environmental conditions Ozone (O3) produced by photochemical reaction involving pollutants; causes stipple on leaves Excessive water causes wilting, stunted growth, chlorosis, abscission of lower leaves Plant diseases |

Plant Environment: Light
Plant Environment: LightPlants convert light energy into chemical energy 6H2O+6CO2+light --> C6H12O6 + 6O2 photosynthesis Photosynthesis provides plant with energy for growth Effects of light on plants important in horticulture Light |

Native and Invasive Plants
Native and Invasive PlantsBest adapted to local conditions Advantages of using native plants Species available for all local soil and light conditions Provide habitat for native wildlife Perennials; do not need to plant each year Reduces need for herbicides, fertilizers and irrigation Part of local heritage “Wherever I go in America, I like it when the land speaks its own language in its own regional accent” -- ‘Ladybird Johnson, 1993 Native plants = plants that evolved in local area |

Killer whales and sea otters
Killer whales and sea ottersWhere have all the sea otters gone? Daily caloric requirements: Male killer whale: 308,000 Kcal/day or 5-7 sea otters Account for 40,000 sea otters lost over 6 years? 5 sea otters per day per whale x 365 days x 6 years = 10,950 sea otters! Female killer whale: 187,000 Kcal/day or 3-5 sea otters 10,950 sea otters eaten x 4 whales would account for 40,000 sea otter losses Killer whale and seal otter energetics |

Digestive Systems
Digestive SystemsAccessory organs Exocrine gland between stomach and small intestine Produces several digestive enzymes: trypsin: digests proteins pancreatic amylase: digests starches lipase: digests fats Also acts as endocrine gland produces hormones to regulate glucose levels in blood (insulin and glucagon) Pancreas Functions of digestive system: |
