Explain how environmental conditions determine how well plants survive and grow.

Summarize the distinct stages of the life cycle of seed plants.

Explain how the basic properties (texture and capacity to hold water) and components (sand, clay and humus) of soil determine the ability of soil to support the growth and survival of many plants
