As mentioned in the previous answer, animals are heterotrophic by ingestion, and plants are autotrophic by photosynthesis.

Some more:
Plants store starch as a form of energy; animals store glycogen.
Plants have intracellular junctions called plasmodesmata; animals have gap junctions, desmosomes, and tight junctions.
There are also differences in reproduction - animals begin development as hollow balls called blastulas. I'm not sure about the details of early plant development, but if you're interested you could look that up.

And to reply to red rose: plants certainly don't have circulatory systems the way we do, but they do transport sap and water is vessels - some might define this as a circulatory system. Just a heads-up to the asker. ;o)

Plants can undergo photosynthesis! plants are the only living organisms here on earth that can produce its own food from scrap. They are the only ones who can turn light energy (sunlight) to food and other products. Therefore making them independent on other animals. When comparing their structures with animals, animals do have a more complex system. But they accumulate and gain their energy from plant products like food and oxygen.

All above answers areo.k.bu t in cellular level plant cell has cell wall made up of cellulose and hemicellulose, the cell wall is dead wall. But in animals only cell mem;brane is there .Cell wall is absent
Again inside the cell, plant cell has plastids(chloroplasts , chromoplasts, and leucoplasts) animal cell lacks them.
Animals have circulatory and nervous systems , but not plants.These are the few major differences, in cellular level.
One more thing both plant and animals undergo respiration to release energy by oxidation of food

animals undergo respiration (they take in oxygen and release Carbon dioxide). Plants do just the opposite thru photosynthesis they take in CO2 and release oxygen as waste.
