Nuclear membrane
The cell's membrane allows only certain substances to diffuse in and out of the cell.
Most animal cells (except for human red blood cells and some others) have a nucleus. It is like a control centre in the cell which allows some substances to enter and others substances to leave the cell. It also initiates chemical reactions and processes like respiration in the cell cytoplasm.
The part that allows nutrients to enter the cell is the cell membrane. The cell membrane is a selectively permeable barrier that regulates the movement of substances in and out of the cell, allowing essential nutrients to enter while keeping harmful substances out. The nucleus and vacuole have different functions and do not play a direct role in nutrient uptake.
The main function of the cell membrane is to regulate the movement of substances in and out of the cell. It acts as a barrier that allows essential molecules to enter the cell while keeping harmful substances out. Additionally, cell membranes also help maintain the cell's shape and provide structural support.
The permeability of the cell membrane controls which substances may pass in or out of the cell.
Nuclear Membrane
The cell's membrane allows only certain substances to diffuse in and out of the cell.
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.

Cytoplasm holds all the organelles in place.
The cell membrane acts as a barrier that controls the movement of substances in and out of the nucleus. It has specific channels and transport proteins that selectively allow certain molecules to pass through while blocking others. This regulation helps maintain the internal environment of the nucleus and ensures proper functioning of the cell.

Compose the what?
The process of substances leaving a cell is called diffusion. The cell membrane is a selective permeable membrane that only allows certain materials to enter or leave the cell.
