Multicellular organisms are living beings composed of multiple cells organized into specialized structures called tissues, which work together to perform specific functions.
These organisms range from simple forms like sponges and algae to complex organisms such as plants, animals, and fungi. Cell differentiation allows cells within multicellular organisms to take on specific roles, enabling tasks like nutrient absorption, locomotion, and reproduction.
This organizational complexity allows multicellular organisms to adapt to diverse environments and exhibit sophisticated behaviors, contributing to the richness and diversity of life on Earth.
