Cellulose is a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright.
The stem
It has long, spiny leaves and yellow or reddish flowers on a stiff, upright stem. The seeds produce an edible oil. Safflower grows to a height of about 3 ft (1 m).
Sclerenchyma.
A vessel is stiff when its center of gravity is low, making it careen with difficulty. It returns rapidly to the upright position, with greater force. Opposite of TENDER. A vessel is tender when its center of gravity is high, making it careen easily, i.e., it is topheavy. It returns slowly to the upright position, with relatively little force. The opposite of Stiff.
All living organisms are cells or are composed of cells. Only plant cells have cellulose which makes them stiff and upright. Plants need cellulose because they don't have bones like you and me.
stem the stem sticks straight.
If a plant cell is turgid it is swollen, distended, congested or stiff
it is the cell wall which protects and supports the plant cell:)
