The light we see from very distant galaxies was emitted millions of years ago, and in the case of the farthest objects we see, the light was emitted 8 billion years ago. So when we look at the universe, we're looking at its past.

First, the morphological structure of algae species
1. Algae is usually invisible to the naked eye and requires the help of a microscope. The smallest is less than 1 micron, and the largest seaweed can reach up to 60 meters.
2. The colors of algae are colorful and have everything. Most of them are just like the names of the phyla, such as green algae is mostly green, red algae is mostly red, and cyanobacteria are mostly blue-green.
3. The structure of algae includes
(1) Single cell type
(2) Root foot type
(3) Glue group type
(4) Spherical shape
(5) This shape
(6) Tubular type
(7) Tube branch type
Second, the life cycle of monocytogenesis
Third, the general conditions required for algae culture
Fourth, the expansion tool
5. Algae seeds and culture medium
Sixth, the cultivation operation steps
1. Culture medium preparation; 2. Tool disinfection; 3. Algae inoculation; 4 Culture management and maintenance
6.1 Culture preparation
6.2 Tool disinfection
After washing the tool, irradiate with a UV lamp for 20 minutes to sterilize. For example, small heat-resistant containers are disinfected by boiling with heat.
6.3 Algae inoculation
Vaccination time: 8:00-9:00
Vaccination ratio: 100:400:7
That is, 100 ml of algae seeds + 400 ml of sterilized water + a total of 7 ml of the above culture medium; after 3 days of observation, observe the color turn green, and continue to expand the culture according to the proportion of the last inoculation.
6.4 Cultivation management
Method 1: shake, before the expansion of the algae species is small, you can increase carbon dioxide replenishment by shaking, divided into morning, middle and evening to 3 times.
Method two: inflation, expanded to 2-5 liters, can take the air pump mode for 24 hours or intermittent inflation.
Supplement: According to the actual weather conditions, rainy days, natural light shortage, by turning on the LED lights to supplement the light.

Long to come to Japan
That year's graduation party was so brightly lit that we couldn't seem to see each other's sad faces. After saying that we will see each other often, I did not expect to see each other again.
使命：There are mysteries to the universe we were never ment to solve. But who we are,and why we are here,are not among them. Those answers we carry inside.
There are many mysteries in the universe that we can never solve, but our identity and the reason for our existence are not unsolvable, and the answers are in our bodies.
愿景：Whenever you look to the stars,think of one of them as my soul. Defend this family,algae,as they have you,defend all they can be.
When you look up at the stars, please take one of the stars as my soul, please guard this family, the algae. Just as they guard you, guard them, guard their future.
