What are cell parts andtheir functions?

Even if cells are very tiny, they are made up of smaller parts, and the parts do different jobs.

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 theme park, which provides shape and protection for it.

“Supporter and Protector”

cell membrane The cell membrane holds and protects

the cell. It controls what substances come into and out of the cell like an gate guard of a theme park.

“Gate of the Cell”

cytoplasm The cytoplasm is the watery, gel-like

material in which cell parts move and cell activities take place like the pathways that lead around the theme park.

“Area of Movement”

mitochondria The mitochondria produces most of the

energy for the cell, like an electrical system of the theme park, which supplies electrical energy.

“Powerhouse of the Cell”

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 food stands at the theme park that makes and sell food.

“Food Producers”

vacuoles The vacuoles store food, water, and

chemicals, like stock room behind the scenes at the theme park.

“Storage Tanks”

nucleus The nucleus regulates and controls cell

activities, acting like the “brain” of the cell, like the control room, which regulates and controls activities of the theme park.

“Control Center”

nuclear membrane The nuclear membrane protects the nucleus

and also allow substances to pass in and out of the nucleus. Just like the cell membrane does the same for the cell. It’s like the control room office, which protect the controls and let workers in and out.

“Gate of the Nucleus”

chromosomes The chromosomes direct the activities of

cells like a theme park director who works in the office and directs all the activities of the park.
