QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Adaptations.
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

(1) To absorb more water from the air
(2) To excrete excess salt from plant tissues
(3) To increase photosynthetic rate
(4) To attract pollinators
