• What does phytography deal with?

  Descriptive terminology of plants
• What is the purpose of phytography?

  To provide vocabulary for plant description
• Why might non-biologists struggle with plant structures?

  They may lack accurate terminology
• How do biologists rely on phytography?

  They use standardized terms for clear communication
• How would you describe "five leaves at one point of the stem" using phytographic terms?

  Whorl of five leaves
• What are the purposes of phytographic studies?

  • Equip students with vocabulary for plant communication
  • Enhance observational skills and descriptive accuracy
  • Emphasize precision in terminology
• What is phenology in relation to plants?

  Study of flowering time
• Why are flowers ideal for taxonomic classification?

  They provide consistent structures for identification
• What is used if flowers are absent in classification?
