The cell wall is the outermost layer of the cell. It is stained a light blue color. The cell membrane is the thin layer that surrounds the cell wall. It is not visible in the image, but it is located between the cell wall and the cytoplasm. The nucleus is the large, dark blue structure in the center of the cell. The cytoplasm is the jelly-like substance that fills the cell between the cell membrane and the nucleus. It is stained a light pink color.
Cell wall: The cell wall is the outermost layer of the cell, and it is only present in plant cells, fungi, and some bacteria.
It is made up of a variety of materials, including cellulose, hemicellulose, and lignin. The cell wall provides support and protection for the cell.
Cell membrane: The cell membrane, also known as the plasma membrane, is a thin layer that surrounds all cells.
It is made up of a phospholipid bilayer, which means that it has two layers of phospholipid molecules.
The cell membrane is semipermeable, which means that it allows some molecules to pass through it while blocking others.
This is important for regulating the flow of materials into and out of the cell.
Nucleus: The nucleus is the control center of the cell. It contains the cell's DNA, which contains the instructions for making all of the cell's proteins.
The nucleus is surrounded by a nuclear envelope, which is a double membrane that protects the DNA from damage.
Cytoplasm: The cytoplasm is the jelly-like substance that fills the cell between the cell membrane and the nucleus.
It contains all of the cell's organelles, which are tiny structures that perform specific functions.
Some of the most important organelles include the mitochondria, which produce energy for the cell; the endoplasmic reticulum, which helps to synthesize and transport proteins; and the Golgi apparatus, which packages and secretes proteins.
