Why diffusion is faster in water?
Why diffusion is faster in water? This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together. What is the slowest diffusing […]

Why do plant cells have cell walls and animal cells do not?
Why do plant cells have cell walls and animal cells do not? Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but […]
