Plant Anatomy starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Anatomy.
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 11
A student observes a cross-section of a plant stem and notes the presence of vascular bundles arranged in a ring, a distinct cortex, and a central pith. Is the stem most likely from a monocot or a dicot plant?
Describe the difference between apical and lateral meristems.
Describe the main difference between open and closed vascular bundles.
Describe the main function of phloem tissue in plants.
Describe the role of the endodermis in plant roots.
Explain the difference between simple and complex permanent tissues in plants.
Explain the function of the Casparian strip in plant roots.
