Chapter 3 Cyanobacterial Communities
Zhang Fan couldn't bear the moving speed of the cell empire. The paramecium had already gone back and forth several times, but the whole empire could barely move forward by a few millimeters. Days seemed like years!No, degrees seconds days years.

Now, Zhang Fan didn't care about it, cut off the contact with the outside world, and entered a dormant state.

The entire cell empire moved in an orderly manner according to Zhang Fan's original plan.

After an unknown amount of time, the Cell Empire was approaching the volcanoes, and Zhang Fan also woke up. Here he could clearly feel the temperature in the lake rising, and ordered the Empire to stop advancing.

Zhang Fan sent Paramecium to investigate again. Now it is about ten kilometers away from the volcano group, so the impact is not too great.

But he knew that he came here this time to look for metal elements. If he couldn't get the metal elements, the whole group would stagnate.

There is a huge rock about 3 meters away from the cell empire, but the paramecium can only move a distance of 2 meters at most.

So Zhang Fan's empire moved again.

During this period, Zhang Fan was not idle either. He kept exploring, trying to find a substitute for chlorophyll. Unfortunately, he was neither a scientist nor a creator.

A distance of one meter is nothing to a formed life, but it is like a natural barrier to a cell.

One meter away from the rock, Zhang Fan stopped. After a long journey, the entire cell empire was gone.

The cells are also alive, and they will perish before they can be replenished in time. Fortunately, the number is still relatively large, leaving Zhang Fan with the opportunity to start all over again.

Because there is no attack from other cells, Zhang Fan can easily expand his empire.

But this kind of expansion will always have an upper limit, and after the death rate is directly proportional to the birth rate, it will no longer expand.

Single cells have a short lifespan, and only multicellular organisms get a lot of time to live.

The work of the entire empire has been on the right track. The paramecium is responsible for the transportation, and the bacteria themselves provide food for the paramecium. Ordinary cell division and fusion, and a part of the cells are taken out for the chlorophyll experiment.

Chloroplasts are easy to solve, as long as a space is opened inside the cell and a film is added.

But Zhang Fan has never been able to understand the production of chlorophyll, and the teacher didn't teach him when he was studying!

After a long period of exploration, Zhang Fan successfully produced a pigment that can be used for photosynthesis, cyanophyll.

Although the color is blue, the photosynthesis effect is not bad.

So Zhang Fan called the cells composed of chlorophyll cyanobacteria.

This is another great creation after Paramecium, enough to be recorded in history.

Zhang Fan ordered the cell empire to start converting into cyanobacteria, and everything was proceeding in an orderly manner.

The element content here is very rich. In addition to nitrogen, phosphorus, potassium, iron, magnesium and zinc, there are also some heavy metal minerals.

This mineral will produce a small amount of radiation, which is not a bad thing for Zhang Fan. He can use this radiation to change his own needs and strengthen the group.

Thinking about the power of the atomic bomb explosion, the radiation is insignificant now, Zhang Fan believes that with time, the atomic bomb will be able to be resisted one day.

But we must overcome the immediate difficulties.

"What's going on! Stop it!" No matter what Zhang Fan ordered, the entire cyanobacteria group just didn't listen to him, and was constantly moving towards the lake, faster than the paramecium.

Zhang Fan was about to cry, and the blue algae that finally gathered did not listen to his command.

After thinking into the blue-green algae community, I realized that it was not a problem with my order, but bubbles appeared in the blue-green algae during photosynthesis.

The bubbles were not released effectively, and then the entire cyanobacteria community was lifted up to the lake by buoyancy.

This is already a natural effect, but no matter what Zhang Fan does, he can't resist it. This is an uncontrollable factor.

It was a huge mistake made by Zhang Fan himself.

There is still a kind of luck in his heart, but after the cyanobacteria that just entered the lake came into contact with the sun, a large area died under the ultraviolet rays.

Within 5 minutes, hundreds of thousands of cyanobacteria groups all died.

Zhang Fan really wants to cry but has no tears. The generation of bubbles is inevitable. The only thing to do now is how to survive under the ultraviolet rays.

Originally, the problem of cell wall was considered, but the appearance of cell wall hindered the movement and shape change of cells.

As far as the current situation is concerned, the cell wall plan has to be implemented.

The cell wall is a thicker, tougher and slightly elastic structure located outside the cell membrane. Its components are mucus complexes, and some species also have a capsule composed of polysaccharides outside the wall for protection.

The capsule itself can also serve as a nutrient substance for cells, which can be utilized by cells when nutrients are lacking.

The production of cell walls is relatively simple, polysaccharide compounds, the required hydrogen elements are everywhere, carbon elements are obtained from rocks, and oxygen elements can be produced by themselves.

After a complicated operation, the cell wall was successfully covered on the cyanobacteria.

Watching the cyanobacteria community rise again, Zhang Fan decided to give it a go and split the cell empire into two.

One part stayed near the rock and continued to absorb elements, while the other part rose to the surface of the lake with the cyanobacteria to absorb energy.

The vertical drop between the two sides is almost a hundred meters, which is a distance that the two communities are completely unable to contact at present.

Fortunately, distance has no effect on Zhang Fan, he can change his mind at any time, or both at the same time.

Cyanobacteria with cell walls survived on the surface of the lake and expanded very slowly.

Looking down from the air, you can see a thin layer of blue-green algae growing on the lake.

The cell colony under the water didn't stay idle either, and gradually approached the rock, using the rock as a base, and the cell empire covered it.

What about paramecium?
It also has its own mission, divided into three legions, the first legion continues to explore the surrounding environment, the second legion is the porter of cells, and the third legion is the porter of blue algae.

What should I do next?Zhang Fan fell into deep thought, and he thought of biodiversity.

This diversity usually includes three components: genetic diversity, species diversity and ecosystem diversity.

Genetic diversity is an important part of biodiversity. Any species or individual organism preserves a large number of genetic genes. Therefore, it can be regarded as a gene pool. The more genes a species contains, the greater its impact on the environment. The stronger the adaptability.Gene diversity is the basis of life evolution and species differentiation.

Now the genes of cyanobacteria, paramecium, bacteria and cells are all derived from the first cells, called founding cells.
