No, they don't.
main parts of an animal cell are the... Cell Membranes, Ribsomes, Nucleus(plural is Nuclei), and the Cytoplasms.
A tissue membrane is a thin layer of tissue that covers or surrounds structures in the body. These membranes serve various functions like protection, secretion, absorption, and support. Examples include the mucous membranes lining the digestive tract and the synovial membranes in the joints.
There are four different membranes in the body that are related to tissue; cutaneous membranes, mucosal membranes, synovial membranes, and serous membranes.
The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes. Mucous membranes are tissues that line body cavities or canals such as the throat, nose, mouth, urethra, rectum, and vagina. Serous membranes line body cavities (peritoneum) and surround organs such as the lung (pleura) and heart (pericardium). The cutaneous membrane is the skin. This membrane is composed of a layer of epithelium over a layer of connective tissue. Synovial membrane is a layer of connective tissue that lines the cavities of joints, tendon sheaths, and bursae (fluid sacs) and makes synovial fluid, which has a lubricating function.

An oxygen molecule must pass through four cell layers to move from an alveolus into the bloodstream: the alveolar epithelial cells, the capillary endothelial cells, and their basement membranes. This process is essential for oxygen exchange in the lungs.
One gram of carbohydrates equals four calories.

The four main types of fats found in cells are triglycerides, phospholipids, cholesterol, and saturated fats. Triglycerides store energy, phospholipids are major components of cell membranes, cholesterol is important for cell structure and signaling, and saturated fats provide structure and insulation.
