The right answer is The plant cell wall provides a more rigid structure.
Plant cells are differentiated from animal cells by the cell wall (among others, they differ in size, vacuoles and the presence of chloroplasts). This wall, called the pectocellulosic wall (composed of pectin and cellulose), gives a rigid structure to the cell and a polygonal morphology to the cell.
While a sodium atom has 11 electrons (the same number of protons), a sodium ion has one less electron an atom to give it a positive +1 charge.
It is called Analogy. Practically equivalent to structures are those structures in various species which play out a similar capacity, have comparable appearance and structure yet are not developed together; along these lines don't share a typical precursor.
Cases of practically equivalent to structures run from wings in flying creatures like bats, feathered creatures, and creepy crawlies, to balances in creatures like penguins and fish. Plants and different living beings can likewise exhibit similar to structures, for example, sweet potatoes and potatoes, which have a similar capacity of sustenance stockpiling
