Cellulose is an essential organic molecule, and its sturdy structure provides a wide variety of functions. It is a significant component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches so strong and firm.
Cellulose is a tough, fibrous, and water-insoluble polysaccharide that plays an integral role in keeping the structure of plant cell walls stable, which, when present in the cell wall are known as cellulosic cell-wall. Whereas organisms having an absence of cellulose in their cell wall are called non-cellulosic cell-wall. Non-cellulosic cell wall function is to act as pressure vessels, preventing over-expansion of the cell when water enters. Instead of cellulose in their cell wall, are being replaced with chitin, pectins, etc. For eg.- Monera have a cell wall of protein plus polysaccharide compound, but not cellulose, All fungi have a cell wall made of chitin. I hope this general concept would clear your doubts.

(x) All real numbers are complex numbers.

i) Is a statement because can either b false or true. It can never ask a question, give a command or make a request.

ii) Mathematics can be difficult for some but not for all. It is not sure whether it is true or false. therefore it is not a statement.

iii) Its is a statement as it is true. The sum is greater than 10.

iv) As we dont know what the number is, therefore it not sure it is false or true, hence it is not a sttatement.

v) Not all quadrilateral has all sides equal, so it is not a statement.

vi) As it is a command/order therefore it is not a statement.

vii) Product is -8 ie False, hence it is a statement.

viii) This statement is always true. It is a statement.

ix) Today doesnot clears about a particular day, hence it is not a statement.

x) It is always true. hence it is a statement.

Example 1

Mathematics is  fun.

It is a sentence but not a statement because the subject mathematics can be fun for some but not for others who do not like it. 

Example 2

Do you like to eat fast food?

Hence, it is a question (ends with "?" sign), can not be a statement.

Example 3

Wow, That's amazing!

Statements can either be true or false and never ask a question, give a command or make a request.
