6 Science Humor Images That Make You Smile

Sharing is caring!

A picture is worth a thousand words. I want to share with you 6 science humor images that make me smile. – and also the points that make me smile.

Let’s dive in!

Cell division humor

Background

DNA molecules are very, very long threads and they are dis-organized in the nucleus called chromatin. The DNAs need to condense and form chromosomes before the cell division. This condensation ensures the proper separation of the DNA.

4. The phase of mitosis

Funny points

The thread of DNA is still in a mess, so the chromosome who are ready for mitosis is laughing at the thread of DNA.

Cell biology humor

Background

The nucleus is the brain of the cell. It stores most of our genetic information (in the form of DNA) and coordinates the function of each organelle.

In contrast, mitochondria, which also have their own DNA but only encodes 13 genes for making the components of the electron transport chain.

The endoplasmic reticulum (ER) is a very important organelle. It performs protein and lipid synthesis, protein folding, and modification.

The Golgi apparatus (or Golgi) usually locates close to the ER. If you think of ER with ribosomes as the protein factory in the cells, the Golgi then takes over the logistic work. The Golgi apparatus receives the raw protein products from the ER, modifies them (for example, adding tags made by sugar chains), and exports the proteins to a variety of destinations.

The lysosomes are small organelles that work as the recycling center in the cells. They contain enzymes that break down whatever substance entering the lysosomes into raw materials.

Funny points

The nucleus is like a boss, a control freak. Every organelle has to do what it says.

Because the mitochondria have their own small DNA, they can say “No” to the nucleus!

ER functions as a manufacturing and packaging system, and it usually works very hard. No wonder it says “I have so much work to do. Be quiet, you guys”.

Because Golgi is very busy with modification, package, and transport of proteins, I can imagine that it needs a break.

Lysosomes contain enzymes that break down whatever substance entering the lysosomes, therefore, it says “Everything I touch, I destroy”. Isn’t it funny?

Finally, the function of vacuole is for storage, so it says “I feel quite fulfilled”.

Amoeba humor

Background

The amoeba eats its prey by a process called โ€œphagocytosis. As the amoeba moves towards its prey, its pseudopods (part of membrane directed by the cytosol movement) reach out, surround, and engulf the food inside the amoeba by forming a food vacuole. Then the digestive enzymes are released into the vacuole to break down the food into small nutrient molecules.

Amoeba phagocytosis

[In this figure] The illustration of phagocytosis.
The pseudopods first surround and bring the food particle close to the amoeba. Then a part of the cell membrane opens to allow the particle to move into the cell and into a food vacuole where it is digested by enzymes.


Funny points

The way amoeba finds its food is like a “hug”. No wonder amoeba hugs are often fatal.

Bacteria and virus humor

Background

Our impression of bacteria and viruses is that they are disease-causing organisms. We are often confused by the treatment of viruses with antibiotics. Bacteria are living organisms so we can use antibiotics to treat bacteria-causing disease. In contrast, viruses are often smaller than bacteria. Strictly speaking, they are not even a living thing. They can only live and reproduce inside the cells. Without their host, viruses are not “living thing”.

3. Can a light microscope see viruses?
4. The size of the virus

Funny points

I like the facial expression of this bacterium. ๐Ÿ™‚

The bacterium points out the difference between the virus and itself. The bacterium realizes that he/she is talking to a non-living thing. And the virus responds “sigh”. lol

Tardigrade (water bear) humor

Background

Water bears (official name: Tardigrades) are the toughest animal on the Earth. Water bears can survive in hot springs, in the deep ocean (high pressure), under solid layers of ice, and even after exposure to deadly irradiation.

For more information about tardigrades, please check out our posts:

2. A video of Tardigrades

Funny points

This image is a picture of a tardigrade. One of its characteristics is to survive in extreme conditions, such as high pressure. No wonder it says “I work well under the pressure.”

Plant humor

Background

Monocot plants differ from dicot plants in five distinct structural features: seeds, leaves, stems, roots, and flowers.

Seeds
The monocot has single cotyledon and embryonic leaf while the dicot has two cotyledons and two embryonic leaves.

Leaves
The monocot veins in the leaves are parallel while the dicot veins are net-like, reticulate.

Stems
Monocot stems have the vascular bundles scattered throughout the plant interior. In contrast, the vascular bundles in dicot stem are arranged in a ring, with pith concentrated at the core of the stem.

Roots
The monocot roots can not increase their diameter as they grow; instead, they grow more roots. The dicot roots have a long and deep primary root, with smaller secondary root growing laterally off the primary root (tap root system).

Flowers
The monocot flower parts are number in the threes or multiples of three, while dicot flower parts are number in the fours or fives.

Funny points

This is great way to remember the monocots and dicots.
