4. What is a Cell? A Cell is the most basic unit of life
There are two different types of cells
Animal cells are also known as Eukaryotic Cells
Eukaryotic Cells are cells that have a distinct cell nucleus and other membrane-bound organelles
Cells are the building blocks of life
Example:
The building blocks of a house is the foundation and the wood frame

5. Parts of an Animal Cell
Cell Membrane is the outside covering of the cell, which is made up of a thin layer of lipids (fats)
Functions of the Cell Membrane:
To separate the cell contents or organelles from the external environment
Used as a protective barrier from the surrounding environment
To allow raw materials (carbohydrates and proteins) to enter the cell
To allow newly made proteins and waste to exit the cell

6. Parts of an Animal Cell
The nucleus is the “brain” of the cell, it controls all the cell’s activity
It is surrounded by the nuclear membrane, which functions are similar to the cell membrane
The nucleus also contains chromosomes, which are small strands of genetic material
Chromosomes are a complex of DNA, RNA and proteins
Nucleolus is a specialized structure in a nucleus that is the site of ribosome synthesis.
Ribosomes are structures in which cell proteins are assembled, They appear as beadlike structures on the endoplasmic reticulum

7. Parts of an Animal Cell
Cytoplasm is a jellylike substance between the cell membrane and the nuclear membrane
It contains several specialized structures called organelles
The endoplasmic reticulum is a network of membranes that connects the cell membrane to the nucleus
There are two sections of the endoplasmic reticulum, which has its own function
The smooth endoplasmic reticulum is the site for the production of lipids (fats) and hormones
The rough endoplasmic reticulum is the site for the production of proteins

8. Parts of an Animal Cell
Mitochondria are small, egg-shaped organelles that manufacture adenosine triphosphate (ATP)
ATP is used as an energy source for the cell
Lysosomes are round organelles that cause the digestion of proteins through the release of enzymes
These are made by the Golgi complex
The Golgi Complex consists of flattened membrane sacs that receive substances transported from the endoplasmic reticulum
It also stores the substances and alters their chemical structure
This is where proteins are processed, sorted or modified
