What are cell parts and their functions?

1
What are cell parts andtheir functions?
Cells
2

• Even if cells are very tiny, they are made up of
  smaller parts, and the parts do different jobs.
  Cells are the building blocks to all life.

3
As you can see cells have many parts. This week
you will learn about 9 of these parts.
4
cell wall

• The cell wall is only in plant cells.
• Its purpose is to shape and protect the cell like
  the outside wall of a shopping mall, which
  provides shape and protection for it.
• Supporter and Protector

5
cell membrane

• The cell membrane holds and protects the cell. It
  controls what substances come into and out of the
  cell like an entrance you have to pass to get
  into the shopping mall.
• Gate of the Cell

6
cytoplasm

• The cytoplasm is the watery, gel-like material in
  which cell parts move and cell activities take
  place like the hallways of the mall where people
  move.
• Area of Movement

7
mitochondria

• The mitochondria produces most of the energy for
  the cell, like an electrical system of the
  shopping mall, which supplies electrical energy.
• Powerhouse of the Cell

8
chloroplast

• The chloroplast is only in plant cells, like the
  cell wall. It contains chlorophyll, which
  captures energy from sunlight and uses it to
  produce food for the cell like the pizza shop in
  the mall that makes food.
• Food Producers

9
vacuoles

• The vacuoles store food, water, and chemicals,
  like water tank and pipes of the mall, which
  store water.
• Storage Tanks

10
nucleus

• The nucleus regulates and controls cell
  activities, acting like the brain of the cell,
  like the mall office, which regulates and
  controls activities of the shopping mall.
• Control Center

11
Golgi Bodies (Apparatus)

• The Golgi Bodies look like a stack of pancakes,
  they take the materials manufactured by the
  endoplasmic reticulum and process them.
• They would be considered the cash register at
  shopping malls.

12
Endoplasmic Reticulum

• The Endoplasmic reticulum can be smooth or rough.
  
• The ER functions as a manufacturing and packaging
  system.
• The endoplasmic reticulum has ribosome's attached
  to it and processes those materials and moves it
  throughout the cell. It is the shopping cart at
  the mall.
