Cell Membrane (Plasma Membrane):

The cell membrane is a thin barrier that surrounds the cell, separating the inner contents (cytoplasm) from the external environment. It controls what enters and leaves the cell and protects the cell's internal components.

Cytoplasm:

The cytoplasm is a jelly-like substance that fills the cell and contains all the organelles and cellular structures except for the nucleus. It provides structural support to the cell and is the site of many cellular processes.

Nucleus:

The nucleus is the control center of the cell. It is a membrane-bound organelle that houses the genetic material (DNA) of the cell. DNA contains the instructions that control the cell's activities.

Organelles: Organelles are specialized structures within the cytoplasm that perform specific functions essential for the cell's survival. There are many different types of organelles, each with a unique role. Here are some of the major organelles:

·        Endoplasmic Reticulum (ER): The ER is a network of membranes that helps with protein synthesis, transport, and lipid production.

·        Ribosomes:

Ribosomes are tiny structures that are responsible for protein synthesis. They read the instructions from DNA and assemble amino acids to create proteins.

·        Golgi Apparatus: The Golgi apparatus is responsible for packaging, modifying, and transporting proteins and other molecules throughout the cell.

·        Mitochondria:Mitochondria are known as the powerhouse of the cell. They break down glucose molecules and produce energy for the cell in the form of ATP (adenosine triphosphate).
