2
What is A Cell?

• A Cell is the functional unit of all living
  Organelles.
• There are many types of cells.
• A cell has three main parts and they are the
  nucleus, cytoplasm and cell membrane

3
Components of Cell Membrane

• All cells are surrounded by a cell membrane.
• The Cell Membrane maintains the integrity of cell
  as well as controlling the passage of materials
  in and out of the cell.

4
Organelles Ribosome

• An organelle is a structure with a specific
  function
• The Ribosome is composed of DNA and Protein.
• Ribosome are found in the ER membrane and
  cytoplasm, a supportive framework.

5
Lysosomes and Peroxisomes

• Lysosome and Peroisomes, both contain enzymes.
• Lysosomes digest worn cellular parts
• Peroisome breaks down lipids and other materials

6
Golgi Apparatus

• It packages protein for transport and secretion.
  It is made up of sacs.

7
Endoplasmic Reticulum

• There is a rough and smooth Endoplasmic
  Reticulum.
• The Rough has Ribosome, the smooth does not.
• The rough ER transports and synthesizes protein.
  The smooth ER synthesizes lipids.

8
The Nucleus

• The Nucleus stores genetic information and serves
  as the control center of the cell.
• The nucleus is surrounded by a nuclear Envelope.

9
The Nucleus (continued)

• The nucleus is surrounded by a nuclear envelope
  which is the double membrane of the nucleus.
• It separates the contents of the nucleus from
  the cytosol, an internal fluid

10
The Nucleus (continued)

• The Nucleus is surrounded by nuclear pores which
  serve as a passage way for cell
• At the center of the nucleus is the nucleolus,
  which is where ribosome synthesize occurs.

Off TopicThe Brain

• The Brain coordinates movement and behavior.
• Most living things have a brain.

Interesting Facts Brains

• The average weight of a brain is 1,300 grams for
  adults. Two percent of a humans weight is the
  brain
• Injuries to the brain tend to affect large areas
  of the brain, sometimes causing major deficits
  intelligence.
• Brain is studied in many fields of science
  including psychology
