The primary growth of a stem?
increases the length of the stem
What tissue separates cortex from pith in older alfalfa stem?
The vascular cambium separates the cortex from the pith in older alfalfa stem. It is responsible for secondary growth, producing xylem toward the inside and phloem toward the outside, contributing to the stem's increased girth.
What happens during primary growth of the stem?
During primary growth of the stem, new cells are produced in the apical meristem located at the tip of the stem. These cells differentiate into various types of tissues, such as epidermis, cortex, and vascular tissues, allowing the stem to increase in length. The elongation of cells in the stem is mainly due to cell division and expansion.
Why do woody dicot stems increase in diameter?
Woody dicot stems increase in diameter through secondary growth, which involves the activity of the vascular cambium. The vascular cambium adds new cells to both the xylem and phloem, increasing the girth of the stem over time. This process is important for providing structural support and transporting water and nutrients throughout the plant.
Define meristems and explain its role in primary and secondary stem growth?
Meristems are areas of cell division that are found at the tip of the stem and just behind the tip of the root of a plant. They provide the cells that are needed in plants to produce height. They also aid secondary stem growth by forming additional cells to increase width.
How does the girth of stem increases from year to year?
More material is added on its outside from year to year (giving rise to annual growth rings).

Why is tree bark in pieces?
Tree bark containing of dead cells does not grow in girth with the increasing diameter of the stem hence it is seen in small pieces around the stem.
Increases in stem length occur at the?
Increases in stem length occur at the apical meristem, which is a region of cell division located at the tip of the stem. This meristem is responsible for producing new cells that contribute to the growth and elongation of the stem.
Are papaya trees soft stem or hard stem?
Yes. Mango Tree has a stem. The size of stem increases with the age of Tree.
Why is the stem of terrestial plants strong?
The stem of terrestrial plants are strong to support themselves as they grow upward. Without this physical characteristic, they would simply fall over after growing a few inches.
What tissue separates cortex from pith in older alfalfa stem?
The vascular cambium separates the cortex from the pith in older alfalfa stem. It is responsible for secondary growth, producing xylem toward the inside and phloem toward the outside, contributing to the stem's increased girth.
Are the tissues of the stem tip primary or secondary tissues?
The tissues of the stem tip are primary tissues, which are derived from the apical meristem. Secondary tissues, on the other hand, are produced by the lateral meristem (vascular cambium and cork cambium) and are responsible for increasing the girth of the stem over time.
Is a 5.5 inch girth good for a 13 year old?
yes it is good
