Cell Membranes

Learn facts on cell membranes with cool pictures.

Cell Membrane:

The cell membrane is like the control tower at an airport. The cell membrane regulates what enters and leaves the cell, just like a control tower at an airport is sees what plane land and what plane takeoffs from the airport.

Nucleus:

The nucleus of a cell is like a teacher in a class room. The nucleus controls the cells activities, just like a teacher controls the activities in their class room.

 

Chloroplast:

Chloroplasts of a cell are just like solar panel. The chloroplast contain green pigments that trap energy for use of photosynthesis, just like a solar paneluses the sun’s energy and change it to energy that we can use everyday.

Mitochondria:

Mitochondria of a cell are like a turbine. Mitochondria are small compartments partitioned by membranes; these organelles are often called the “power plants” of the cell because their main job is to make energy, just like a turbine makes energy for peoples use.

Ribosome:

A ribosome is like honeybees. Ribosome builds proteins according to mRNA instructions, just like honeybees produce honey according to the directions given to them.

Rough Endoplasmic Reticulum:

The endoplasmic reticulum is like a subway. The endoplasmic reticulum is a series of channels that transport material from one area of the cell to another, just like a subway transport people from one place to another.

Golgi Apparatus:

A Golgi apparatus is like Santa Clause’s workshop. The Golgi apparatus packages and sores various molecules produced by the cell, just like how elves in Santa’s workshop make toys for little kids.

Vacuole:

Vacuoles are like water bottles. Vacuoles are storage area in cells, plants cells often have a big one for water, just like how water bottles hold water for people and you can carry it around.

Lysosomes:

Lysosomes are like a garbage disposal system. A lysosome are compartments that contain enzymes to break-down old cell parts and other cellular debris, just like a garbage disposal breaks down your food and garbage.

    Well, this is cute. I loved the imagery. It may help beginning biology students make the associations they need to make to study the cell. BTW you have a typo: under Golgi body, you have sore s/b store.

    The rough ER contain ribosomes, which are the site of protein synthesis. I don’t really understand the “subway” image. Well, I guess they are fast.

    Also of note: Chloroplasts are not in animal cells. AND plants have a slightly different cell membrane (cell wall} AND bacteria have a different chemical composition to their cell membrane, which makes it possible to kill germs without killing the host.
