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

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

Germination – the development of the seed into a plant

Seeds

• Conifers-seeds are exposed in a _______

• Angiosperms- _________ plants, seeds are protected in a ________

ConeFlowering

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
