The materials is necessary for scientists to estimate the age of the solar system is meteorite sample.
<h3>What is the procedure of calculating the age of solar system?</h3>
The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years. The oldest rocks on Earth are dated as 3.8 billion years.
The solar system has been defined as a system which is gravitationaly bound of the sun and orbit is occupied by object. The formation of solar system takes place 4.6 billion years ago and this happens due to gravitational collapse of a giant molecular cloud. The most and wast majority of the systems mass in the sun and other part of mass contained by the planet Jupiter.
Therefore, The materials is necessary for scientists to estimate the age of the solar system is meteorite sample.

Answer
Cellulose, lignin and suberin are the chemicals that provide rigidity to cell wall.
Explanation
In plant two type of growth occurs, primary and secondary growth. in primary growth when new cells are formed they are bounded by primary wall whose composition in mainly of cellulose. in secondary growth accumulation of lignin in secondary wall, suberin in cork cell wall and lignin in xylem cell wall occurs which provide rigidity.
