CELL WALL

• The cell wall is a rigid layer that surround some type of cells. it's not found in every cell it's just found in plant cell which means that animal cell does not have cell wall.
• FUNCTIONS:
• Gives the cell shape and structure
• Provides structural support.
• Prevents water loss.
• Protection against infections.
• 

CELL MEMBRANE

• Cell membranes protect and organize cells. Cellular membranes, including plasma membrane and internal membranes are made of glycerophospholipids molecules made of glycerol, and two fatty acid chains. Cell membranes are found in plant cells and animal cells.
• 

NUCLEUS

• The cell nucleus is a membrane bound structure that contains the DNA. It is in the command center of an eukaryotic cell and it is the most important organelle in the cell.
• 

NUCLEOLUS

• 
• The nucleolus is the largest structure in the nucleus of the eukaryotic cell. Like the nucleus is the "brain" of the cell, the nucleolus can be thought as the "brain" of the nucleus.
• The nucleolus primary function is to assemble ribosomes.

NUCLEAR MEMBRANE

• 
• A nuclear envelope is made up of two membranes: an outer membrane and a nuclear membrane. The nuclear membrane keeps your DNA inside the nucleus to protect it from surroundings substances in the cytoplasm.

CYTOPLASM

• The cytoplasm is the cell substance between the cell membrane and nucleus, containing the organelles, and various particles. The cytoplasm helps to fill up space and keep the organelles in its place. If there wasn't cytoplasm, the cell would be deflated and materials would not be able to pass easily.
• 

VACUOLE

• The vacuole is the storage structure in a cell.
• Main function is structural support.
• Found in plant and animal cell.
• 

RIBOSOMES

• Ribosomes are the cell's protein factories.
• Make proteins
• found in all cells.
• Found attached to the Endoplasmic Reticulum and floating free in the cytoplasm.
• 

MITOCHONDRION

• A mitochondrion is an organelle, a specialized structure found inside almost all eukaryotic cells. It is called the "power house of the cell" because of their roll in cellular respiration and energy production.
