Physical Weathering
This especially happens with granitic rocks as they were cooling, like at Yosemite National Park. Freeze-thaw: When water freezes, it expands. If moisture seeps into cracks before winter, it can then freeze, driving the rocks apart.
Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
