  • EBiochemistry


Who was the scientist that first established a system of classification in plants?

  • ALinnaeus
  • BMendel
  • CDarwin
  • DHooke
  • ENewton


Which word describes the basic level of classification, a group of organisms that can interbreed and produce fertile offspring?

  • APopulation
  • BTaxon
  • CHybrid
  • DKingdom

What do the organisms shown in the figure have in common?

young green ice-edited
bush tree-edited
  • AThey all reproduce using spores.
  • BThey all have roots, stems, and leaves.
  • CThey all reproduce using flowers.
  • DThey all live in aquatic habitats.
  • EThey all have chlorophyll.


The figure shows a sago palm (Cycas revoluta).

What plant group does it belong to? Why?

Sago palm tree
  • AAngiosperm, because it does not produce seeds
  • BGymnosperm, because it does not produce seeds
  • CAngiosperm, because it does produce flowers
  • DGymnosperm, because it does produce flowers
  • EGymnosperm, because it does not produce flowers
