In a skin cross-section, the different layers and structures visible include the epidermis (outermost layer), dermis (middle layer), and subcutaneous tissue (innermost layer). The epidermis contains layers of cells, including the outermost layer of dead skin cells. The dermis contains blood vessels, nerves, hair follicles, and sweat glands. The subcutaneous tissue is made up of fat cells and connective tissue.
The three layers of cells in a triploblastic worm are the ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer). These layers give rise to different tissues and organs in the body of the worm, allowing for more complex body structures and functions.
There are different types of cells, but the structures are basically same, with similar organelles and other structures.
Because every cell is different!
All cells ARE NOT the same shape. Cells can be of diverse structures.

Plant and animal cells share common structures such as the nucleus, cell membrane, and mitochondria because they are essential for basic cellular functions. However, they have different structures like chloroplasts in plant cells for photosynthesis and centrioles in animal cells for cell division, reflecting their distinct functions and specialized adaptations to their environments.
They all have different jobs to do.
The cells that develop differently are generally called the cells. The genetic cells however determine the relation between a number of individuals.
Stem cells are unspecialized cells that have the potential to develop into different cell types in the body.
The process of embryonic tissue development where tissue layers form during animal development is called gastrulation. This process involves the rearrangement and differentiation of cells to create distinct layers that will give rise to different body structures and organs.
