  1. PLANTAE

  2. Vocabulary • Autotroph: An organism that can make its own food • Fertilization: Joining of a sperm and an egg cell • Phloem: Vascular tubes that carry food throughout the plant • Photosynthesis: the process plants use to produce glucose (food) for themselves and oxygen for the air

  3. Vocabulary • Pollination: the transfer of pollen from the anther to the stigma in a flower • Transpiration: the releasing of excess water in the form of a gas from the plants leaves • Xylem: vascular tubes that transport water and minerals throughout the plant

  4. Characteristics • Multicellular • Autotrophs or ______________________ • Cells have ____ _____ and _____________ • Colors can be vibrant to attract insects and birds for pollination Producers Cell Wall Chloroplasts

  5. Structure (Fill in Chart) A: Leaf • Site for photosynthesis • Called food factories B: Stem • Support: for the leaves; used in transport • Stores food • Ex: celery

  6. Structure (Fill in Chart) C: Roots • Anchor: holds plant in soil • Absorbs: water and minerals • Some plants store food • Ex: potatoes, carrots, turnips

  8. Photosynthesis • Process by which green plants use carbon dioxide, water, and light energy from the Sun to produce glucose (food) and oxygen • Occurs in the plant’s ______ Leaf

  9. Photosynthesis • Provides most of the atmospheric _____________ • Equation: 6CO2 + 6H2O C6H12O6 + O2 Oxygen O2 Sunlight ------------------- Chlorophyll

  10. What food do green plants make? • What organelle contains chlorophyll? • What gas in the air is produced by plants? Glucose Chloroplasts Oxygen

  11. Transportation • Phloem-Transports____ from the leaves to the rest of the plant • Xylem-Transports ____ and _______________from the roots to the rest of the plant Food Water Dissolved minerals

  12. Transpiration • Process of _______loss through the plant’s ___________________ Water Leaves----stomata

  13. Flowers Female • Pistil-_______ part of the flower that produces the __________ • Stamen-______ part of the flower that produces the __________________ eggs male Pollen grains--sperm

  15. Flowers Pollination • _____________- transfer of ______ from the stamen to the pistil - How? Wind, insects, birds, bats, even water • ___________- joining of a sperm and an egg cell, occurs after pollination Pollen Fertilization

  16. Flowers • Once the egg is fertilized, it develops into a ______ and the ovary develops into a ______ to protect the seeds • Seeds are dispersed (Spread) by wind, water, gravity, and animals Seed Fruit

  17. Seeds • Structure • A Seed Coat :________ covering • B-Cotyledon: Stored _______ • C-Embryo root • D-First Leaves protective Food Germination – the development of the seed into a plant

  18. Seeds • Conifers-seeds are exposed in a _______ • Angiosperms- _________ plants, seeds are protected in a ________ Cone Flowering Fruit

  19. Ecological Succession • Changes in a community that occurs over a long period of time • Going from a state of grasses to a forest • Example: Burning of Long Island Pine Barrens
