Answer: You're right its urban
Attached is the experiment details. I found the exercise on the internet.
The pigments of the algae, according to the experiment, absorb the most strongly around the violet-blue and red parts of the spectrum and so photosynthesis is the most efficient when the algae are under such wave lengths. The results were that more oxygen-seeking bacteria gathered around the algae that were under such wave length because there were more production of oxygen.
If the pigments were now to absorb most strongly around the 500 nm to 560 nm, the bacteria would gather the most around the algae under such wavelegth (green light).
Answer:
But in multicellular organisms, cells are grouped to form tissues. These tissues are specialised to carry out a particular function at a definite place in the body. For example, the muscle cells form muscular tissues which helps in movement, nerve cells form nervous tissue which helps in transmission of messages.

The cell cycle can be separated into two major phases that alternate with each other: interphase, during which the cell grows, prepares for mitosis and duplicates its DNA, and the mitotic (M) phase, in which the cell divides into two genetically identical daughter cells.
