PATHOLOGY

Detailed explanation-1: -All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts.

Detailed explanation-2: -Cell Membrane-The outside boundary of the animal cell, the part next to the cell wall in a plant. In both cells, it controls what enters and exits the cell.

Detailed explanation-3: -The cell membrane separates the material outside the cell, extracellular, from the material inside the cell, intracellular. It maintains the integrity of a cell and controls passage of materials into and out of the cell.

Detailed explanation-4: -The nucleus is a key structure in all eukaryotic cells, as it stores all of the cell’s DNA (and therefore, genetic information). The nucleus also controls and regulates all the vital functions of the cell, including protein production, cell division, metabolism, and growth.
