Life Science Concepts and Vocabulary

This video from Moomoomath introduces key life science vocabulary, including multicellular and unicellular organisms, tissues, organs, and organ systems. It explains that multicellular organisms consist of multiple cells, while unicellular organisms have only one cell. The video further describes tissues as groups of similar cells working together, and organs as structures made of tissues performing specific functions. Finally, it covers organ systems, which are groups of organs working together to perform complex functions, using the respiratory system as an example.
