What do you think keeps multicellular organisms alive?
Examples of organs in animals include the heart, lungs, liver, kidneys, and brain.
Examples of organs in plants include leaves, roots, stems, flowers, and seeds.
Not all animals, including tiny bugs, have a nervous system. In animals that do have a nervous system, it is responsible for sending and receiving signals to and from different parts of the body to coordinate movement, respond to stimuli, and regulate bodily functions.
An example of a structure in plants and animals that is similar is the circulatory system. In both plants (xylem and phloem) and animals (blood vessels), these systems transport essential nutrients and fluids throughout the organism.
Multicellular organisms are organisms composed of multiple cells that work together to carry out specialized functions necessary for survival. Examples of multicellular organisms include humans, animals, plants, and fungi.
For multicellular organisms to stay alive, their cells must work together in a coordinated manner to carry out essential functions such as obtaining nutrients, eliminating waste, reproducing, responding to stimuli, and maintaining homeostasis.
