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.
Which tissues present in the dicot stem is meristematic in nature?
In a dicot stem, there are two areas of meristematic growth. The apical meristem which is located at the tips of roots and shoots, and the lateral meristem which contributes to outward growth.
What part of a plant produces secondary growth?
The vascular cambium, a layer of cells between the xylem and phloem tissues in the stem, is responsible for producing secondary growth in plants. This results in the thickening of the stem and roots as new layers of xylem and phloem are added.
Do Woody plants lack secondary growth?
No, woody plants do not lack secondary growth. Secondary growth is the process by which plants increase their girth through the production of secondary tissues such as wood and bark, which woody plants exhibit. This growth allows woody plants to increase in size and longevity.
How does the stem be more stronger to support the plant?
Formation of stele as a result of secondary growth makes the stem more stronger
Why do monocot plants not show secondary growth?
In a monocot stem, vascular bundles are scattered throughout the stem. However, because the of the lack of vascular cambium, no secondary growth occurs in the monocot stem. As a result of increased cell size, the monocot stem will only increase in height only.
What is difference between primary growth and secondary growth?
Primary growth is when the stem or root of a plant gets lengthens, and secondary growth is when the stem/root gets thicker.
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.
What does the stem do for the stem?
Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness
Which tissues present in the dicot stem is meristematic in nature?
In a dicot stem, there are two areas of meristematic growth. The apical meristem which is located at the tips of roots and shoots, and the lateral meristem which contributes to outward growth.
Are the tissues found in the monocot stem primary?
Yes, the tissues found in the monocot stem are primarily primary tissues. These tissues include the epidermis, cortex, vascular bundles, and pith, which are responsible for growth and support in the stem.

How do plants that lack secondary growth increase (stem width)?
cells get bigger
