Criteria for Classification
Biology ⇒ Biological Classification
Criteria for Classification starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Criteria for Classification.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12

Explain why the mode of reproduction is considered an important criterion in biological classification.
Explain why the presence of a cell wall is an important criterion in classifying organisms.
