Transcript of How a cell is like a school


How a cell is like a School
Nucleus
Nuclear Envelope
The Nuclear Envelope is like the main office in a school-it controls who goes in and out of the cell.
Mitochondria
/Chloroplast
The Mitochondria / Chloroplast is like the boiler room of the school it helps to transform energy in the cell (school).
Cytoplasm
The cytoplasm is like the school secretary it helps the nucleus (Principal) get it's work.
Ribosomes
The Ribosomes are like the Vice Principal because it takes orders from the Nucleus.
Lysosome
The Lysosome is like a school caretaker because it helps to remove the trash and keep the cell (school) clean.
Vacuole
The Vacuole is like the cabinets in the school it helps to store supplies in the cell.
The Nucleus is like the Principal because it's in charge of what happens in the cell (school).
Rough
Endoplasmic Reticulum
The Rough Endoplasmic Reticulum is like the Vice Principal's office in a school because that's where the Ribosomes (Vice Principal) works in a cell.
Golgi Apparatus
The Golgi Apparatus is like the teacher it helps the Endoplasmic Reticulum (students) get its work done.
Cell Membrane
The Cell Mebrane is like the school because it helps everything in the Cell (school) stay in the Cell (school).

Cell Wall
How it's like a school
The Cell Wall is like the brick walls on the school they hold the cell (school) together.
Cell Parts and Their Functions
Nucleus
- Large Oval body near the centre of the cell.
- The control centre for all activity.
- Surrounded by a nuclear membrane.

Nucleoplasm
- is the protoplasm in the nucleus.
- contains genetic material ---> CHROMOSOMES (DNA)

Nucleolus
- is found in the nucleus.
- contains more genetic information (RNA)

Cell Membrane
- the outer boundary of the cell.
- it separates the cell from other cells.
- it is porous ---> allows molecules to pass through.

Cell Wall ( Plant Cells Only )
- non living structure that surrounds the plant cell.
- protects + supports the cell.
- made up of a tough fibre called cellulose.

Cyto Plasm
- cell material outside the nucleus but within the cell membrane.
- clear thick fluid.
- contains structures called organelles.


Vacuoles
- are clear fluid sacs that act as storage areas for food, minerals, and waste.
- in plant cell the vacuoles are large and mostly filled with water. This gives the plant support.
- in animal cells the vacuoles are much smaller.

Mitochondria
- power house of the cell.
- centre of respiration of the cell.
- they release energy for cell functions.

Chloro Plasts ( Plant cells only )
- contains a green pigment known as chlorophyll which is important for photosynthesis.

Ribosomes
- tiny spherical bodies that help make proteins.
- found in the cyto plasm or attached to the endo plasmic reticulum.

Endo Plasmic Reticulum ( ER )
- systems of membranes throughout the cyto plasm.
- it connects the nuclear membrane to the cell membrane.
- passageway for material moving though the cell.

Golgi Bodies
- tube like structures that have tiny sacs at their ends.
- they help package protein.

Lysosomes
- " suicide sacs "
- small structures that contain enzymes which are used in digestion.
- if a lysosome were to burst it could destroy the cell.
