Questions and Answers

Which of the following is true about the effects of environmental factors on plant growth and development?

  • Plant growth and distribution are not affected by the environment
  • Environmental factors do not have any impact on plant growth and development
  • Environmental factors can limit plant growth and affect the distribution of plants (correct)
  • Only one environmental factor is responsible for limiting plant growth

How do limiting factors affect the geography of plant distribution?

  • They determine the migration patterns of plants
  • They control the types of plants that can grow in a specific area (correct)
  • Limiting factors have no impact on the geography of plant distribution
  • Limiting factors influence the size of the plant population

What is the primary cause of most plant problems, according to the text?

  • Biotic stress only
  • Genetic factors
  • Abiotic stress only
  • Environmental stress, either directly or indirectly (correct)
