1. A group of similar cells that work together to perform a function is called

a tissue! Tissues are the building blocks of organs and systems in living organisms. For example, in humans, you have muscle tissue for movement, epithelial tissue for protection and absorption, and connective tissue that supports and binds other tissues. It’s like a team of cells combining their strengths to achieve a common goal! When it comes to real-world applications, understanding tissues is vital in fields like medicine and biology. Researchers analyze tissue types to develop better treatments for diseases, like cancer, where abnormal tissue growth occurs. This knowledge helps in crafting targeted therapies and improving health outcomes, showing just how crucial tissues are to our overall biology!
