What occurs during secondary growth?
Secondary growth is characterized by an increase in thickness or girth of the plant. It is caused by cell division in the lateral meristem. Herbaceous plants mostly undergo primary growth, with little secondary growth or increase in thickness.Jun 8, 2022
What is the process of secondary growth?
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.
How does the process of secondary growth happen?
Secondary growth occurs at the lateral meristems. The cells at the meristems undergo cellular division, where each cell multiplies into two daughter cells and add to the cellular material collectively called tissue. Secondary growth in plants produces secondary phloem and xylem.Mar 28, 2022
What is secondary growth and how it occurs?
The secondary growth of plants increase in stem thickness and it is due to the activity of the lateral meristems, which are absent in herbs or herbaceous plants. There are two types of lateral tissues involved in secondary growth, namely, vascular cambium and cork cambium.
What is secondary growth produced by?
Meristems contribute to both primary (taller/longer) and secondary (wider) growth. Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium.
How does secondary growth take place in stem?
Secondary growth involves the thickening of the plant axis through the activity of lateral meristems. The end result of secondary growth is increased amounts of vascular tissue. As plants grow larger, more vascular tissue is needed for water conduction and the transport of nutrients.
What occurs during secondary growth in a stem?
Secondary growth involves the thickening of the plant axis through the activity of lateral meristems. The end result of secondary growth is increased amounts of vascular tissue. As plants grow larger, more vascular tissue is needed for water conduction and the transport of nutrients.
What is a secondary growth in stem?
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.
When secondary growth begins in a stem?
In many seed plants, secondary growth begins in their first year within the stem and continues on for many more years. These plants are classified as woody. They develop secondary tissues like periderm and wood, and even tertiary structures like bark.Apr 10, 2020
In what part of a stem does secondary growth occur?
Secondary growth occurs at the lateral meristems. The cells at the meristems undergo cellular division, where each cell multiplies into two daughter cells and add to the cellular material collectively called tissue. Secondary growth in plants produces secondary phloem and xylem.Mar 28, 2022
Where are secondary growth occurs?
Cambium is the layer of actively dividing cells between xylem and phloem tissues that is responsible for the secondary growth of stems and roots. The cambium produces new layers of phloem on the outside and of xylem on the inside, thus increasing the diameter of the stem.
