Epidermal cells originate from stem cells in the basal layer of the epidermis. As they mature, they move up through the layers of the epidermis, undergoing changes in shape and structure. Once they reach the top layer, known as the stratum corneum, they are dead but serve to protect the body from external elements.
To examine leaf epidermal cells, a leaf sample is typically cleared with a clearing solution to make the cells transparent. The cleared leaf sample is then mounted on a slide with a drop of water and covered with a coverslip. Finally, the sample is observed under a microscope to study the size, shape, and structure of the leaf epidermal cells.
Epidermal cells in sponges serve as a protective barrier, helping to prevent pathogens and debris from entering the sponge's body. They also play a role in gas exchange and waste removal by allowing for the diffusion of molecules across their cell membranes. Additionally, epidermal cells can secrete substances that aid in capturing food particles from the water.
The shape of a human cheek cell is influenced by its function and structure in the body, which includes maintaining tissue structure and facilitating absorption. Onion epidermal cells, on the other hand, are specialized for protection and support, resulting in a different shape and structure to serve their purpose in the plant. This difference in function leads to the variation in cell shape between the two organisms.

Answer1. Guard cells have chloroplast, epidermal cells do not have.2. Guard cells are much smaller than the epidermal cells.3. The cell walls of guard cells are not uniform, inner walls are thicker than the outer walls. epidermal cells are unformly thin.

Epidermal cells of tomatoes typically exhibit a polygonal shape, often resembling hexagons or irregular polygons due to their close packing. The dominant pigments in these cells are primarily carotenoids, which give tomatoes their characteristic red color, particularly lycopene. Additionally, chlorophyll may be present in younger, green tomatoes, contributing to their green coloration before ripening.
