What are the differences between monocots and dicots? What are some adaptations of rainforest plants? How do ferns adapt to their environment? Name four adaptations of desert plants How does an ovule form plants's ploidies? How are other gymnosperms similar to pine?
Why are plants autotrophs? Why are the leaves of some plants small? Why is the stomata important? Why do plants survive polyploidy? Why are trees considered a renewable resource? Why is grafting successful in dicots? Why are plant roots important to prevent erosion? Why do ferns produce so...
