PLANTAE

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

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

Characteristics Multicellular Autotrophs or ______________________ Cells have ____ _____ and _____________ Colors can be vibrant to attract insects and birds for pollination CellWall Chloroplasts Producers

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

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

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

Photosynthesis Provides most of the atmospheric _____________ Equation: 6CO 2 + 6H 2 O C 6 H 12 O 6 + O 2 Oxygen O 2 Sunlight  Chlorophyll

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

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

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

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

Flowers _____________- 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 Pollination Pollen Fertilization

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

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

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

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

Review - Motion Objects in motion stay in motion unless acted on by an outside force Friction opposes motion to slow an object down To reduce friction you can add wheels to an object, make the surface smooth, or lubricate (oil, grease, or wax) the surface
