Cells that live in the ocean are often starved for phosphate and so their growth

Question

Cells that live in the ocean are often starved for phosphate and so their growth is P limited. Cells that need less P to grow will have an advantage over cells that needs lots of P to grow. Which of the following might provide an evolutionary advantage to a bacterium growing in an environment where P is scarce. Check all possible answers which apply: the cells evolve to have very few proteins per cell the cells evolve to have a very small number of ribosomes the cells evolve to have a very small genome the cells evolve to have a very small diameter the cells evolve a cell wall that lacks peptidoglycan

Explanation / Answer

Phosphate is the main component of Genome. Infact, it is reservior of Nitrogen, carbon and phosphorous. Thus if any bacteria is evoloving in area with limited phosphate then it will have small genome

Hence option 3 will be correct : the cell evolve to have very small genome.
