This resource explores the cellular organization in various multi-cellular organisms. It examines the building blocks of plant cells, the strings of fungal mycelium, and the sheets of animal cells, highlighting differences in tissue layers across species. Through electron microscope images and cross-sectional views, we delve into the anatomy of sunflowers, oyster mushrooms, and sponges. Moreover, the resource provides insights into human organ systems, demonstrating the complexity of multi-cellular structures and their functional significance in different organisms.
