• 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
• 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
• 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
• 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
• 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
