Two macromolecules that provide support to a cell are collagen and cellulose. Collagen is a protein found in the extracellular matrix of animal cells, giving structural strength and support to tissues. Cellulose, a carbohydrate, is a key component of the plant cell wall, providing rigidity and protection. Both macromolecules play crucial roles in maintaining the integrity and shape of cells in their respective organisms.
The type of cell that possesses a specific shape and structure to perform a particular function is known as a specialized cell. For example, red blood cells are biconcave in shape, which increases their surface area for efficient oxygen transport. Similarly, nerve cells (neurons) have long extensions called axons and dendrites that facilitate communication within the nervous system. Each specialized cell type is adapted to fulfill its unique role within an organism.
Cells whose main function is absorption would typically have a large surface area, such as microvilli or brush border, to increase their ability to absorb nutrients or substances. Additionally, these cells may have specific transport proteins and channels to facilitate the movement of molecules into the cell. They may also contain high concentrations of mitochondria to provide energy for the absorption process.
No prokaryote cells do not have a distinct nucleus. The prokaryotes are a group of organisms whose cells lack a membrane-bound nucleus. Organisms whose cells do have a nucleus are called eukaryotes.
The cells in the human nervous system that provide insulation and structure for neurons are called glial cells, specifically oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. These cells produce myelin, a fatty substance that wraps around the axons of neurons to insulate and support their function by speeding up the transmission of nerve impulses.

Red blood cells transport oxygen, and white blood cells are part of the immune system, whose function is to destroy invading germs (or cancer cells).
