Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive overview of the animal kingdom, specifically focusing on non-chordates—animals lacking a spinal cord. The lesson begins by defining the fundamental characteristics that classify an organism as an animal, such as being eukaryotic, multicellular, and heterotrophic. It distinguishes animal cells from plant cells by noting the lack of cell walls, which facilitates movement—a critical trait for finding food.
