Actually, most living things do not have a heart. It is only when you get to the more complex organisms, like worms and above, that you start to see hearts, and these are only a very small minority of living things on Earth.

NO
All living things to not have a heart. Plants do not, nor do any single cell organisms. They are all considered living, but use different methods to absorb and circulate nutrients.
Plants generally use photosynthesis to convert nutrients to energy. Single cell organisms can use chemical reactions, photosynthesis, or the digestion of other organisms.
Hearts only exist in certain multi celled organisms.
Hope this helps.

Plants have a vascular system but no pumping mechanism like a heart.
Many microorganisms do not have a pumping mechanism like a heart.

No. No plants do, and many animals don't either.
