What gives the stem strength and stiffness?
Collenchyma cells in the ground tissue have unevenly thickened primary cell walls with higher cellulose content, and therefore can offer some rigidity to young stems (Leroux, 2012).
Which plant has strong and hard stem?
1) Trees have hard and thick stem called trunk, such as mango and coconut. 2) Shrubs have short, woody stems with branches growing near the ground, such as in a rose plant.

How do plants maintain their shape and strength?
Plant Cell Structures The large central vacuole is surrounded by its own membrane and contains water and dissolved substances. Its primary role is to maintain pressure against the inside of the cell wall, giving the cell shape and helping to support the plant. The cell wall is located outside the cell membrane.
What makes a plant stiff?
Key factors that control plant stiffness include the force of gravity upon the stem, the weight of branches and leaf canopy, and the flow-induced stresses upon the whole plant due to wind acting upon the canopy , .
Which plant has a very juicy stem?

Which plants have woody stems?
➡️Trees are big and tall plants. ➡️They have very thick, woody and hard stems called the trunk. ➡️This single main stem or the trunk gives rise to many branches that bear leaves, flowers and fruits.
Do plant cells change shape?
Plant cells can change their shape with the help of the cytoskeleton present in the cytoplasm in the stress conditions. They can also change the shape by changing the amount of water in and out of the cell by the process of endosmosis and exosmosis. This movement of water out of the cell is called exosmosis.
