Exploring Cellular Organization in Multicellular Organisms: Plants, Fungi, and Animals

This overview delves into the cellular structure of multicellular organisms, comparing the building blocks of cells in plants (block-like), fungi (string-like mycelium), and animals (sheet-like arrangement). Utilizing electron microscope imagery, we examine the intricate cellular designs present in species such as oyster mushrooms (Pleurotus) and sunflowers (Helianthus). Additionally, we discuss the variation in tissue layers across different organisms, including sponges and humans, highlighting their unique anatomical features and organ systems through informative resources.
