Cell surface markers serve as identifiers for cells, allowing the immune system to recognize and differentiate between self and non-self cells. They also play crucial roles in cell communication and signaling, facilitating interactions between cells and their environment, which can influence processes such as immune response, tissue development, and cell adhesion.
Two functions of every cell are to carry out specific metabolic processes to maintain the cell's health and function, and to contain genetic information that is passed on to daughter cells during cell division.
eg,meat,groundnut,groundnut oil,fish,dog meat.
The mitochondria's structure, with its inner membrane folded into cristae, enables it to produce ATP efficiently through aerobic respiration, supporting the cell's energy needs. The endoplasmic reticulum's extensive network of membranes provides a large surface area for protein and lipid synthesis, aiding in the production and modification of biomolecules for cellular functions.
The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells. It consists of the phospholipid bilayer with embedded proteins. Cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signaling and serve as the attachment surface for the extracellular glycogalyx and cell wall and intracellular cytoskeleton.\In easy way:The cell membrane has tiny holes that control the movement of chemicals in or out of cell.Dissolved substances such as food,oxygen and carbon dioxide can pass through cell membrane.Some harmful chemicals are stopped from entering cell membrane.
The two main phases of the cell cycle include interphase and mitotic phase. Interphase is the stage where the cell undergoes normal functions and prepares for division, consisting of G1, S, and G2 phases. The mitotic phase encompasses the actual process of cell division, which includes mitosis and cytokinesis. Together, these phases ensure proper growth, development, and reproduction of cells.
An epithelial cell can be divided into two functional regions: the apical surface, which faces the external environment or a body cavity, and the basolateral surface, which interacts with neighboring cells and the extracellular matrix. These regions are important for different functions such as absorption, secretion, and cell-cell communication.
The functions of the cytoskeleton used in an animal cell, is for the movement of the animal and so that objects within the cell can move.
The two functions of a virus's protein coat are to protect the genetic material inside and to react with the cell wall of a potential host cell, thus causing the genetic material to be injected into the host cell.

Regulation of entry of materials.Removing waste products from cell.
It separates the cell from its surroundings.It protects it from changes in the chemical and physical environment.It regulates the traffic of molecules into and out of the cell.
The cell wall provides structural support and protection for the cell. It also helps regulate the movement of substances in and out of the cell.
interphase
to protect the rest of the parts of that cell and to hold all of the parts together
