A blastula typically consists of a single layer of cells called the blastoderm. This layer forms during early embryonic development and surrounds a fluid-filled cavity called the blastocoel.
Human cheek cells do not have layers like the epidermis of the skin. Cheek cells are simple squamous epithelial cells that form a single layer on the inside of the cheek.
Their apparent number of layers;simple epithelium with a single-layer offer less protection than Stratified epithelium having multiple layers. Also, simple epithelium functions in moving materials across its surface.
Oxygen diffuses through two layers of cells: the alveolar epithelial cells lining the lung air sacs and the capillary endothelial cells before it reaches a red blood cell in the pulmonary capillaries.
A Poriferan typically consists of two cell layers: the outer epidermis and the inner layer of cells called choanocytes. These cells are separated by a gel-like matrix called mesohyl.

The zygote undergoes cleavage, a series of mitotic cell divisions, to form a blastula. Cleavage is important for increasing the number of cells while reducing their size, eventually leading to the formation of a hollow ball of cells known as the blastula.
Squamous cells are flat and circular shaped. These cells are found in many parts of the body such as the mouth, lips, cervix, and the middle layers of the skin.
Cells from a blastula are ideal to examine mitosis because they are actively dividing and undergoing rapid cell division, making it easier to observe the stages of mitosis. Additionally, blastula cells are undifferentiated, which means they have not yet specialized into specific cell types, allowing for a clearer view of the mitotic process.
A leaf is made of many layers that are sandwiched between two layers of tough skin cells
forty-six layers
The pericycle typically consists of one layer of cells located between the endodermis and the vascular tissue in plant roots.
Human cheek cells do not have layers like the epidermis of the skin. Cheek cells are simple squamous epithelial cells that form a single layer on the inside of the cheek.
A hydra typically has two cell layers: an outer layer of epithelial cells and an inner layer of gastrodermal cells. These layers are separated by a jelly-like extracellular matrix called the mesoglea.
