Understanding Plant Life and Processes

Which type of plant completes its life cycle in one year?

• Biennial

• Perennial

• Annual

• Evergreen

What is the main product of photosynthesis?

• Oxygen

• Carbon dioxide

• Sugar

• Water

Which type of plant retains its leaves year-round?

• Deciduous

• Evergreen

• Annual

• Biennial

Explain why plants generally go dormant.

• To conserve water during rainy seasons

• In response to adverse conditions such as extreme heat or cold

• To increase photosynthesis

• To attract pollinators

Which equation represents the process of photosynthesis?

Describe the difference between annual and biennial plants.

• Annuals live more than two years, biennials complete their life cycle in one year.

• Annuals complete their life cycle in one year, biennials in two years.

• Both annuals and biennials live more than two years.

• Biennials complete their life cycle in one year, annuals in two years.

Which type of plant is most likely to grow best in spring or fall?

• Warm season plants

• Cool season plants

• Perennial plants

• Evergreen plants

Analyze how the process of respiration in plants complements photosynthesis.

• Respiration produces sugar, which is used in photosynthesis.

• Respiration consumes oxygen and produces carbon dioxide, which is used in photosynthesis.

• Respiration and photosynthesis both produce oxygen.

• Respiration and photosynthesis both consume carbon dioxide.

What is the by-product of photosynthesis?

• Carbon dioxide

• Water

• Oxygen

• Glucose

Which type of plant typically loses its leaves during the dormant season?

• Evergreen

• Deciduous

• Perennial

• Annual
