Why, and how are plants and animals different?

plants and animals are as different from each other as a rose is different from a rabbit.!
most plants, with a few exceptions like the swimming algae,cannot move about from place to place, while animals can move freely.
most plants manufacture their on food withe help of their green coloring which is called chlorophyll.animals must rely on plants for their food,or hunt other animals.
Animals have a nervous system which makes them sensitive to touch,heat,cold,pain and other stimuli.Plants do not have a nervous system.how were some plants do fold their leaves when touched.others sense that a support is near,and twine themselves around it.
The cell structure of plants and animals is different too.most plants have rigid cell walls, and contain cellulose.animals cells do not have cellulose.
