• Equilibrium• Endocytosis

Exocytosis Na/K pump Concentration gradient

• Hydrophilic• Hydrophobic• Protein channels• Facilitated diffusion

• Primary succession• Seconday succession• Climax community• Phototropism• Gravitropism• Thigmotropism

Cell Transport-Passive (no energy)

Osmotic solutions

Active Cell Transport

Cell Membrane Function

• Homeostasis: the ability of an organism to maintain a stable internal environment to survive

• Cell Membrane: controls homeostasis for cells by allowing substance in and out while maintaining equilibrium.

Cell Membrane Structure

Ecology TopicsSuccession of Ecosystems

• Primary succession-starts with bare rock

Secondary Succession

• Starts with lichen, grasses (pioneer plants) over time creates a climax community

Human Activities on the Environment

• Global warming-excess carbon dioxide

Deforestation and resource depletion

AirPollution

Ozone Depletion

Chemical Pollutants

• F Fertilizers

• The problem???

Plant Adaptations

Plant Tropisms (behavior)

• Bend toward Shoots grow Response the sun/ up, roots down to touch
